Thanks, Allen. And thanks to everyone for joining Vroom’s first quarter 2021 earnings call.
’d like to start by thanking all of our employees, investors, and board members for all of their hard work and support in building a great customer-centric public company. Vroom executed well in the first quarter.
Our e-commerce units exceeded our expectations and we're up 96% year-over-year. Our e-commerce gross profit also exceeded our expectations and was up 123% year-over-year.
But executing well means not only delivering great growth in units and gross profit, it also means strong execution across our four key pillars of demand and marketing, supply and reconditioning logistics, and sales and sales operations. By focusing on these four key pillars, we're building a strong foundation for sustainable scale.
From a demand and marketing perspective, we continue to be enthusiastic about the level of demand that exists in the marketplace, as well as our ability to generate demand for our business model. Demand for both buying cars from Vroom and selling cars to Vroom remains high.
We are building a nationwide brand that is increasingly known for buying and selling used vehicles. And we're pleased that our continued upward trend in brand awareness.
We're confident that his increased demand flows into our business. We are well positioned to convert that demand, as evidenced by our growth in Q1 and guidance for accelerating growth in Q2.
From a supply and reconditioning perspective, I'm also pleased with our performance. We believe our current inventory level is sized appropriately and is healthy for the market.
We not only generated e-commerce gross profit per unit beyond our expectations in Q1, we also see continued improvement in our unit economics going into Q2. We are currently experiencing unprecedented market conditions caused in part by shortage of microchips and delays and new car manufacturing, which increases demand for used vehicles putting downward pressure on supply an upward pressure on pricing.
In this market, we're particularly pleased to be in a position to integrate and leverage the data and data science teams a car story along with this AI powered analytics. As used vehicle supply is constrained and wholesale pricing is high in traditional channels, we're very well positioned to acquire vehicles from consumers and I'm bullish on our trajectory for consumers sourcing.
Over the past three quarters we've experienced strong sequential improvement in acquiring inventory from consumers, increasing as a percentage of retail sales from 31% in Q3 of 2020 to 41% in Q4 of 2020 to 54% in Q1 of 2021. Well historically, Vroom has always had a strong mix of vehicles acquired from consumers, we are demonstrating that we have executed well in scaling our consumer acquisitions platform.
Supply will continue to be a focus and area of investment for Vroom, particularly given the uncertainty over the duration of the current supply and pricing market. We continue to increase both the number of our reconditioning facilities and our overall capacity.
In Q1, we added 5 third party reconditioning facilities for a total of 24 and expanded our capacity at many of our existing facilities. Our hybrid asset light approach to reconditioning continues to provide us with capacity and agility.
We believe that we are well positioned to not only handle our projected 2021 volume, but are also scaling our capacity to handle sales, growth and volume in advance of meeting it for 2020. I'm pleased with all of the improvements we've made in terms of capacity, quality and cost.
And we will continue to invest to build scaled capacity. With regard to the logistics we executed well in our rollout of last mile locations.
In Q1 we added 10 locations and delivered over 16% of e-commerce units via our last mile service. We remain on track to achieve our goal of delivering the run rate of 50% of our e-commerce units be our last mile service by year end.
It's rewarding for our customers in our company to see our brand displayed nationally on television in places like the Superbowl. But it's even more rewarding when we see our brand displayed locally on trucks, delivering customers a great vehicle and a great driveway experience.
We've mentioned our investments in sales and sales support operations, which include investments in people, process and tech. We're continuing to invest in people to mitigate bottlenecks in our processes to remove friction and increase sales flow, and in technology to automate, improve customer experience, and drive conversion.
We executed well across all three of these areas in Q1. We hired trained and coached hundreds of new people.
We streamlined our processes and expanded our sales capacity, and we deployed technology to reduce manual efforts and drive customer experience. But we still have more to do.
I'm pleased with our current improvements, but not yet satisfied. We will continue to invest in sales and sales operations for the foreseeable future.
I'm appreciative of all of the outstanding work from our employees and our valued third party partners who enable us to execute well across our platform. In short, we are experiencing strong demand, record e-commerce sales, improving inventory health and unit economics, increasing reconditioning capacity, expanded last mile deliveries, growing sales and sales support resources.
We are well positioned to deliver triple digit e-commerce unit growth in over 200% aggregate gross profit growth in 2021. And with that, I'll hand over to Dave for further remarks on our financials and our guidance.
Dave?
Dave Jones
Thanks, Paul. We reached the new record and e-commerce units this quarter with over 15,500 units delivering 41% sequential acceleration and 96% year-over-year growth.
Our unit growth was driven by robust consumer demand and improved inventory position and positive response to our increased marketing. We had over 11,000 listed vehicles at the end of the quarter with 35% of those available for immediate sale.
Our inventory is in a much better position than it was in the fourth quarter. We feel good about driving inventory efficiency in the quarter and we're now increasing our inventory buys to continue to meet demand.
As Paul mentioned during the quarter we purchased 54% of the vehicles we retailed from consumers. This was up from 31% in Q3 of 20 and 41% in Q4 of 2020.
Our days to sale expanded from 77 last quarter to 83 this quarter due to a few factors. First, we continue to work on the Q4 bottlenecks and we continue to move this Q4 aged inventory through the system during this quarter.
In addition to ramping those consumer purchases added some time to the acquisition process, but we're making improvements as we scale. Importantly, each of the months in the quarter saw sequential improvements in days to sale, and we expect continued improvement in Q2.
As a reminder, we currently target 60 to 70 days to sale. In Q2, we expect 17,500 to 18,000 e-commerce unit sold implying over 160% year-over-year at the midpoint of that guidance.
We anticipate about 15% sequential growth in units as we grow reconditioning capacity to meet consumer demand while remaining nimble to adjust to a dynamic environment. Our reconditioning capacity continues to build.
As Paul said, we added five new third party VRCs in the quarter, bringing us to 24 total VRCs compared to 19 at the end of 2020. At the end of Q1, we had capacity of about 2300 units per week, implying about 120,000 unit capacity annually.
We believe we're tracking well against our 2021 target of 25 to 30 VRCs which would enable us to reach over 50% of U.S. households within 100 miles of one of our VRCs.
E-commerce revenue grew 81% year-over-year and 48% sequentially in the first quarter to over 422 million. E-commerce gross profit per unit was $2,054 in the first quarter of 2021, demonstrating 14% year-over-year growth and 13% sequential improvement.
Within e-commerce gross profit per unit, our vehicle gross profit improved due to further reconditioning cost improvements, and a decline in inventory reserve balances compared to the prior year quarter, which was affected by higher than normal inventory reserves at the onset of the pandemic. Total gross profit was ahead of our expectations at $36 million, up 97% year-over-year and 80% sequentially.
We expect average e-commerce gross profit per unit in the range of $2,500 to $2,600 in the second quarter, which at the midpoint would imply over 24% sequential growth in Q1. We have good line of sight into our unit profitability in Q2 and expect ongoing tailwinds from the favorable demand environment, as well as our previously mentioned, profitability drivers.
Wholesale units increased 84% year-over-year and 24% sequentially to 8,641 units. Wholesale loss per unit of $33 improved significantly from $420 in the fourth quarter of last year, as the wholesale market was very strong in Q1.
Looking ahead to the second quarter, we expect wholesale units of 7500 to 8000 and gross profit per unit of $800 to $900, as we believe the wholesale market will continue to be strong through Q2. Looking at TDA units were flat sequentially as our e-commerce business continues to demand fast turning inventory.
We expect inventory for TDA to continue to be lean in the near term as we focus on scaling our e-commerce operations in a competitive inventory buying environment. However, in the long term, we remain committed to building a dedicated inventory for TDA to service the local demand.
In the second quarter, we anticipate 1400 to 1500 TDA units, and an average gross profit per unit of $2,000 to $2,100. So if we put it all together, we expect total revenue of 618 million to 640 million and total gross profit of $54 million to $59 million for Q2, implying over 56% sequential gross profit growth and over 600% growth from Q2 of last year, which was obviously affected by the pandemic.
Moving on to operating expenses. First quarter operating expenses of $109 million, represented about 18.5% of total revenue, as our higher than expected revenue gave us some leverage.
Our SG&A dollars grew as expected, as we built the organization for scale. To be clear, we are intentionally currently deploying human capital which is less efficient from an OpEx point of view as we provide for an enhanced customer experience and efficient sales processing times.
While at the same time, we're investing in technology, which will lead to operating leverage as we scale the business longer term. Breaking it down a little further company benefits expense grew 40% sequentially to $39.9 million as we bolstered sales and sales support functions, as well as engineering teams.
As I mentioned, we've continued to prioritize building our customer support teams to help process ever increasing vehicle unit volumes quickly. We continue to capitalize on our hybrid asset light model leveraging outsource parties as an additional resource.
We have made substantial progress on the bottlenecks identified in Q4. But we are continuing to invest in our sales support functions to provide the exceptional customer experience that we want for all of our valued consumers.
We know that over time, technology and automation are the solution to a frictionless customer experience, and we continue to make progress in that regard. Marketing expense was 29.6 million in the quarter growing 65% year-over-year and 68% quarter-over-quarter.
As a reminder, Q1 included the financial effect of our very well received Superbowl commercial. We are pleased with the response to our marketing strategies as average monthly unique website visitors has grown in lockstep with our marketing year-over-year.
On a sequential basis, unique visitor growth accelerated significantly at 54% and year-over-year at 64%. Through the rest of the year, we expect marketing investments to remain higher than 2020 levels in dollar terms, as we scale our business and drive increasing national brand awareness.
Finally, our outbound logistics expense grew 46% sequentially in line with e-commerce unit growth and at a similar per unit cost to last quarter of almost $1,000. We expect a similar carrier environment in Q2.
We continue to rapidly build out our proprietary logistics network. At the end of the quarter, we had 18 logistics hubs up and running up from 8 in Q4 and we delivered over 16% of our Q1 deliveries with our proprietary last mile service.
Customer satisfaction with the experience is high and we remain on track to build out 30 last mile hubs and obtain a run rate of 50% of our total deliveries with our proprietary last mile service by the end of the year. Our first line of haul trucks and trailers are arriving this quarter and we're busy planning the launch of our line haul operations.
As mentioned last quarter, we think logistics CapEx will be up to approximately 10 million for the year. So overall, we expect 61 million to 70 million of EBITDA loss in the second quarter as we anticipate operating expenses at 19% to 20% of total revenue.
We remain on track to deliver triple digit e-commerce unit sales growth, and more than 200% year-over-year growth in aggregate gross profit for 2021. Finally touching on our balance sheet we ended the first quarter with over $950 million in cash on the balance sheet and 162 million of availability on our floor plan facility.
As always, we've provided comprehensive Q2 guidance in our earnings release. I'll now turn it back to the operator for questions.
Operator
[Operator Instructions] Your first question comes from the line of Rajat Gupta from JPMorgan. Your line is now open.
Rajat Gupta
Good afternoon, good evening. Thanks for taking the questions.
I just had a multi part question on the e-commerce GPU. Unfortunately, can you help us bridge either, sequentially or versus your initial guidance was in what your reported like what changed during the last three to four weeks of March.
And then going from the first quarter to the second quarter order? Could you help us unpack the drivers of the sequential update common to seasonality?
How much is just the inventory quality getting better or reconditioning efficiencies or customer sourcing mix, etc? And then just lastly, like what percentage of your inventory today is, would you say is greater than 60 days old?
And what was that number at the beginning of the year? Thanks.
Paul Hennessy
Thanks for the question. Yes, I think when we look at e-commerce, the big story there is sales margin.
It's a great environment. I think that when we look at the skill sets that we have now with the car story acquisition and obviously our internal data teams and data analysts, we feel like we've got a lot of horsepower behind acquiring vehicles.
Obviously, in the first quarter we did a really good job of acquiring vehicles from consumers at 54%. So I think there isn't one thing in particular that I would point two in the quarter.
I think we continued solid product, gross profit per unit. And so I guess where we saw the most upside from guidance was probably in sales margin as it was a good quarter, and we continue to acquire vehicles well.
And I think when we think about Q1 going into Q2, it's similar, we in terms of, if we break it down between vehicle, gross profit per unit and product gross profit per unit we continue to make progress in our efforts to reduce reconditioning costs. We continue to build out the network, which as naturally reduces our inbound miles and helps us with inbound costs.
And obviously sales margin as we continue to get better and better at acquiring vehicles, we continue to acquire more vehicles from consumer. And then on the product side we continue to implement our initiatives and we expect to have stability in product gross profit per unit going forward.
And so I think when you put all those things together what allows us to now raise our target for Q2 to the $2,500 to $2,600 of gross profit per unit that we're getting to. In terms of inventory, like we said we're much healthier than we were.
We had an objective in the quarter to work our way through the problem inventory that we had. We are now, we feel like we've got very healthy inventory which means we've got a good mix of aging across the board.
And we don't have any concerns at this point about aged inventory. So hopefully, that helps you understand.
Rajat Gupta
Got it. Just a follow up on just the pricing you see particularly on the wholesale side, you're obviously done a great job improving the customer source mix, but you still I mean, there's still like a good 45% of your inventory that come from auction or wholesale.
So with this kind of move that we have seen in wholesale pricing, do you think you can pass through all of that into retail or do you I mean or have you baked in I mean, what happens like retail pricing may not catch up like later in the quarter. Is that kind of like considered in the guidance or you assuming that you're able to make up that spread at some point in the quarter?
Thanks.
Paul Hennessy
Yes, so any consideration of that you're right would be in the guidance. The way we think about it, though, is obviously inventory management and turn.
There is no reason to believe that there's going to be a dramatic change in retail pricing. So I think look, we're in the business of buying vehicles and selling vehicles.
I think if we can hit our turn targets and do that efficiently there shouldn't be any undue risk in the current inventory.
Rajat Gupta
Great. Thanks, I will pass it on and thanks for taking the question.
Paul Hennessy
Thanks Rajat.
Operator
Your next question comes from the line of Zach Fadem from Wells Fargo. Your line is now open.
Zach Fadem
Good afternoon. So with the rollout of concierge delivery in markets like LA and Chicago, can you talk about expected impact to customer conversion and satisfaction?
And as in house delivery works its way to 50% what improvements do you anticipate to things like days to sell and GPU as well as lower logistics costs?
Paul Hennessy
I'll take that. Zach I think first and foremost we're getting good control over our logistics network because it just fundamentally allows us to deliver a better experience to our customers we'll stop.
And so that's the strategy and our reason for getting to 50%. And then that satisfaction ultimately leads to better NPS and we believe over time, better conversion and lower cost per acquisition over time because customers have a great experience, and they talk about it and they come back.
And so that's all the strategic thinking behind the logistics network broadly. In terms of cost per acquisition or I should say, a cost of running the logistics network as we deploy closer and closer to customers, as Dave mentioned in his script, as we add more of our facilities in close proximity to customers and as we remove network miles as we deliver both inbound and outbound, the cost structure improves.
And that's how we think about and that's why we're pursuing that. So fundamentally, you get a better customer experience.
You get a better a unit economic benefit for the company and then we believe that you get better cost of acquisition and better conversion because you're delivering an outstanding service.
Zach Fadem
Got it and then with the 200%, gross profit growth still on the table for the year and I think you actually said at least 200% gross profit growth. Is this more a continuation of the upward trends you're seeing in Q2?
Or do you see incremental second half benefits from things like customer sourcing, days to sell? You've called out reconditioning.
I'm curious if you could talk about the drivers there. And then any other internal/external dynamics we should keep in mind.
Paul Hennessy
Yes, we don't give out the underlying pieces. But what I will tell you is we have a good trend that we saw in Q1.
That trend continued into Q2. Our acceleration of e-commerce unit growth is up and to the right.
And so the numbers that we forecasted in our fourth quarter earnings call and now in our first quarter earnings call those numbers are the same triple digit growth in e-commerce and 200% in aggregate gross profit dollars. That's what we believe is going to happen because that's what our models are telling us as we execute on all of the areas of our business from all the pillars that I mentioned on the marketing side certainly on the acquisition side of vehicles.
Consumers obviously play a large role in that. Good reconditioning execution as well as scaling and then the same on logistics.
So it's all of the contributing factors and I'll add in and the sales ops that I mentioned in my opening remarks as we invest in sales operations again the business can process greater scale and that's why we feel good about the guidance that we've given.
Zach Fadem
Appreciate the time today.
Operator
Next question is from Alex Potter from Piper Sandler. Your line is now open.
Alexander Potter
Great, thanks. So the first question was you mentioned the sort of four areas of execution that you're focused on and the fourth one is that sales and operations step, which in recent quarters has been sort of the bottleneck for you.
So I'm interested, it sounds like you're making some progress there. What would you say, you're in terms of getting that issue completely addressed and as an external analyst, looking at a specific metric to gauge your progress there?
I mean, would it primarily be manifesting itself in GPU, in days sales and inventory or what?
Paul Hennessy
Yes, I can't point to one because it's quite literally we use the word bottleneck. It blocks both sales flow when you block sales flow, inventory can age, customer experience can decline, cancellations can increase.
So improving that lifts all boats, if you will. There's not a single metric.
In terms of the ending answer in my opening remarks I said, look, we've made improvements. You see it in our sales velocity.
But we're not satisfied and the commitment to an outstanding customer experience and end to end e-commerce platform experience there's no finish line on that. So we are very committed to getting it right for the customers and we're making good progress.
So I think what I say is, we believe we're in a good spot with room for improvement.
Alexander Potter
And then one more on logistics doing more and more in house I hear you on the 50% target. Assuming everything goes well this gives you more control both on the cost side on the logistics cost side as I mentioned, but also on the customer experience side conversion, everything is better in theory, assuming all goes well.
Is there any reason to think that assuming it does play out that way you would necessarily want to stop at 50% rather than gunning eventually for 100? Thanks.
Paul Hennessy
Yes. We're not slamming on the brakes.
We're just giving guidance as far out as we could see on that. And we believe that giving our customers an outstanding driveway experience that number will likely go north in 2022.
And when appropriate will kind of give some insight and guidance to that. But we're just as you can tell by our first quarter location ads we're just starting to jog on that front.
Alexander Potter
Okay, perfect. Thanks, guys.
Operator
Next question is from Sharon Zackfia from William Blair. Your line is now open.
Sharon Zackfia
Hi, good afternoon. I guess the follow up on the logistics question I mean, obviously, you've had some, as everyone has had some stress in the system from a third party network standpoint over the past few quarters and now you've got the internal initiatives.
Over time where do you think you can drive logistics per car? I mean, if I look back a few years ago, it was sub $300.
Is that a level that you can see again in the next 5-10 years? Or is there something that will be sustainably elevated now with your own network coming into play?
Paul Hennessy
Hi Sharon, thanks for the question. I think obviously we don't give guidance that far out.
We think we can get leverage in logistics with the model that we have today. We literally just started in the past few months and I've personally been amazed that how well the team is rolling it out.
So congratulations to them. Look, I think that the key components are really customer experience, control over the experience and that's what we're after.
But I definitely do think that there is leverage over time. We'll give guidance on that as we get to quarters where we think we'll see some of that leverage, but obviously to get any leverage it needs some scale.
And so we're 16% at the end of the quarter on our way to 50 one of the most clearer view of that as we move through the month here.
Sharon Zackfia
Thanks for that. And if I can follow up with a finance question within the expectation for that 200% increase, you're more than that and gross profit are there embedded expectations that GPU on the finance side, kind of go up as the year progresses and can you talk about what caused kind of a bit of pressure that you saw in the first quarter year-over-year?
Paul Hennessy
Yes. In the guidance, we don't break out to the product versus vehicle.
I would say we've talked a lot about initiatives that we have around product. Obviously I think, the team has done a great job, improving attachment rates.
We've seen very consistent improvement in attachment rates over the past couple of quarters which is great. I think that the variability that we saw this quarter is a couple of percentage, a few percentage points.
So not significant. There's a lot that goes into product gross profit per unit.
We've got charge backs. We've got profit sharing.
There are estimates on reserves. So there is quite a bit that goes in there and then you've got attachment rates and individual product pricing and mix.
And so I think that we have seen and will continue to see an ace ending product gross profit per unit and there will be some variability along the way but it shouldn't be significant. So that's how we think about it.
Sharon Zackfia
That's great color. Thank you.
Operator
Next question is from Ron Josey from JMP Securities. Your line is now open.
Unidentified Analyst
Hi, guys. This is Andrew Green on for Ron, thanks for taking our questions.
I wanted to kind of click into marketing. Can you talk about your learnings from the Superbowl ad?
And just with your plans to increase brand investments are you seeing the type of calls into your call centers change? In other words, are you moving from more kind of a transactional kind of component versus kind of what was historically more educational?
And then I have a follow up.
Paul Hennessy
Yes. We didn't give out specific details about the performance of the Superbowl.
But I think we said we're pleased. And when I think about composition direct traffic that comes seeking the Vroom brand typically converts significantly higher when customers are saying, hey, I know what Vroom offers and I'm seeking to get that service.
And so conversion is just fundamentally higher versus when they might see one of our cars listed on a performance marketing channel or on a third party listing site or something like that, where they're looking for the car, not necessarily the service. So we continue to spend on brand.
We will for the foreseeable future build a super brand so that customers understand exactly what we're offering both on the buy side and on the sell side so that customers can transact with us. And when they come for after seeing the brand, they just convert way better.
So yes, that's how we think about it. And so we'll look for those opportunities to showcase the brand and explain exactly what we have to offer.
Unidentified Analyst
That makes sense. And then just on the consumer source vehicle, just the consistent step up for the last couple quarters.
Can you guys just kind of double click into that and kind of help us understand the drivers there? Thank you.
Paul Hennessy
Yes, I mean, look, we don't give away the whole playbook. But what I can tell you is that we're skilled marketers and we've built a really good technology platform, a data driven technology platform that converts the customers that come in from the strong marketing.
So when you fire on kind of all cylinders that way give customers the right price, a good price for their vehicle and because we're making them aware that Vroom is a great place to go do that we get a lot of appraisals and therefore a lot of transactions. And that's why you see the ascending a move as we increase our consumer acquisitions and platform.
So we're just the truth is we're just executing really well there.
Unidentified Analyst
Fair enough. Thank you.
Operator
Next question is from Seth Basham from Wedbush Securities, Your line is now open.
Seth Basham
Thanks a lot and good afternoon. My first question is just clicking in on the sales margin strength in the first quarter that drove the upside to your gross profit, e-commerce expectations.
How much of that was from strong retail market pricing above your expectations in March relative to better acquisition costs that you anticipated?
Paul Hennessy
Yes, I think it's a tough question because it's the difference between the two. So I guess what I would say is, we had obviously with the guidance that we gave coming out of Q4 for the full year view which was triple digit units and 200% or more in aggregate gross profit.
We had planned obviously on improvements across the board and vehicle gross profit and product gross profit. And what I would say is now through the first quarter, we've obviously started to execute on those well.
I think it's obviously a good market for all automotive retailers today but it's difficult to say how much of it I s, is this great market which by the way we didn't necessarily know how good it was when we gave that guidance originally. So I think we're pretty happy that we've been executing on the plan.
And we think we can continue to do that. And that's obviously reflected in the Q2 guidance where we've got further step up in terms of gross profit per unit.
And so we'll just get to work executing on that as we do every day.
Seth Basham
Got it. Helpful color.
Obviously strong 2Q guidance. You didn't officially raise your full year guidance obviously it's open ended at the top.
And should we be thinking about something a little bit better than you guys were forecasting just in early March?
Paul Hennessy
I think you should be thinking, sorry, I'll just say I just I think you should be thinking about it exactly as we've articulated.
Seth Basham
Alright, fair enough. And then lastly, just thinking about some of the operational challenges you guys faced last fall and into the winter particularly as relates to sales support and extend delivery times.
Could you give us an update on whether or not you've been able to reduce average delivery times and improve net promoter scores over the course of the past six months?
Paul Hennessy
Yes. We don't share those numbers specifically, but you can imagine when you create a bottleneck and it causes all of the downstream problems with inventory, with delivery, with customer experience and then you start to remove those bottlenecks.
Fundamentally, we believe that the system improves and again, you see that in both the sales velocity and the unit economics in the performance of Q1 and the guidance of Q2. So we believe that that's headed in the right direction.
Seth Basham
Wonderful. Thank you very much, and good luck.
Operator
Your next question comes from the line of Edward Yruma from KeyBanc Capital. Your line is now open.
Edward Yruma
Hi, guys, thanks for taking the questions. I guess, first now that you've had some time under your belt with car story just trying to understand kind of how it's changed now that you have it in house versus being a customer there, were able to kind of also keep some of your external customers and then as it relates to the customer service center, you guys indicated with a real progress behind it, continue to invest against it.
I guess, when should we assume that you started to get kind of a more normalized customer service level versus where you were last quarter? Thank you.
Paul Hennessy
Yes. On the car story integration we officially closed the deal in early January and got to work on integration.
So what I'd say it's early days, but outlook is great and performance in the immediate term has been strong. Again I won't get into the playbook of what we do or how we do it.
But we're very pleased with the results and I think there was a question on their existing client lists and we continue to maintain and grow their client list as you would expect. So yes we're, as I, mentioned, we're very pleased, especially in a time of unprecedented kind of market conditions, we are glad to have now the combined team of really-really strong data folks.
As far as the customer experience again we work on that every day and there is no finish line. So speed is in our DNA.
And the faster we can get customers their transaction completed, the faster we can get their car picked up the faster we can get their new car delivered to them those are all drivers of positive customer experience and we're working hard at that. And again, as I said we're making really strong improvements in that and still have a long way to go.
So there is not a date when we'll call that behind us. Because we'll always want to be go faster and better.

Next question is from John Colantuoni from Jefferies. Your line is now open.
John Colantuoni
Thanks for taking my questions. So first I know you are still guiding to triple digit growth in e-commerce unit for the full year.
But I was curious if it makes sense to think about growth on a two year stacked basis for the remaining quarters and in other words, should we expect to see unit growth in the back half that's above the first quarter rate given easier comparisons and follow up?
Paul Hennessy
Hey thanks John. Yes look, we guide one quarter at a time.
I think what I would say is you now have Q1 actual and Q2 guidance. So you've got half the year.
And so I think if you just make, if you guys are obviously going to make assumptions on how to extrapolate that but I don't think, it shouldn't be too difficult to see a path forward to the triple digit number. As you can imagine we just don't want to give guidance past Q2.
John Colantuoni
Okay and just a quick one you provided Q1 guidance with more than two months of the quarter already completed. So I'm just curious what caused that trajectory e-com growth to flex so much in the last few weeks of the quarter?
Was this a function of being conservative or there was there some other dynamic going on? And assuming the last month was better than expected are you seeing continued improvements in e-com unit growth so far in Q2?
Maybe you could just talk about the trajectory there? Thanks.
Paul Hennessy
Yes. I think we always try to be transparent and logical in the guidance that we give.
I think what you saw in the industry has been an accelerating rate of growth in the retail market. So I think there was some, there was more growth than we had obviously expected.
I think what you can expect from us in terms of guidance is we give you a range and we expect to hit that range and that's really as simply as we think about it. So hopefully that answered your question.
John Colantuoni
Thanks so much.

Your next question comes from the line of Nicholas Bacchus from Raymond James. Your line is now open.
Nicholas Bacchus
Hi, guys, thanks for taking the question. So the inventory availability, clearly there's a lot of tightness in the market in the U.S.
market. So how is that impacting your sourcing strategy currently?
And is a tight supply an inhibitor of capacity at this point? And then I had a follow up question after that.
Paul Hennessy
Yes. I guess here is the way we see it.
15 consecutive weeks of ascending wholesale pricing and a fundamental reduction in supply in traditional channels and by the way unprecedented demand for those vehicles, up to and including the rental car companies historically large sellers of used cars are now actually large buyers of used cars. So you've got this massive market situation that's unfamiliar.
And that's why I think in my opening remarks, I said, how great I feel about being able to buy cars from consumers at the rate that we're buying cars from consumers for all of those reasons. And there yes it's constrained and we think we're well positioned to deliver the second quarter that we've guided as well as the annual numbers that we've given.
Yes we believe we're well positioned to execute.
Nicholas Bacchus
Got it. And in terms of the customer source penetration, obviously, that's continuing to go up at 54%.
Where do you think that can get you over time? Do you have a specific target there over time?
And can you just remind us the incremental profitability on a customer source vehicle versus one from auction or otherwise?
Paul Hennessy
Yes. For the first question, we haven't planted some number that we think is the right number like 70% or 75%.
We think it's smart to be able to leverage of buying cars from consumers. There is a large market.
It's massively fragmented and we're pretty good at it. So we're going to continue to drive that number as appropriate.
And yet we'll be opportunistic wherever we see the right car at the right price. we will buy those vehicles and make sure they're available for our customers.
So broadly that's how we think about. We're not setting a target.
As far as the unit economics the way that I'll answer that is it broadly depends on the market, and we're in a strange market typically is bounced between $500 and $1,000 in total value that's an improvement of a car purchase from a consumer versus a wholesale car. But again, that's the mass of aspects of what are the broad market conditions at the time.
Nicholas Bacchus
Thanks very much.

Your last question comes from the line of Naved Khan from Truist Securities. Your line is now open.
Naved Khan
Yes hi, thanks a lot. Just a couple of questions.
So just curious to know how you plan to ramp up the units from the 5,000 that you have to get to the midpoint of the unit sales that you are for second quarter? Do you think you are at the appropriate level or you need to ramp up significantly?
And then I had a follow up question on unit economics.
Paul Hennessy
Sorry, I just wanted to make sure we when you said the 5,000 units that we have, I just want to make sure I understood that number.
Naved Khan
Yes. So I think if you gave out a readily available unit that's available for sale and where do you think you need to be get to the unit sale that you're targeting for second quarter.
Paul Hennessy
Oh, got it. Yes.
So look, we've got the, we're lucky in that our inventory turns very quickly. So as you know, we've got the components of inventory on our website some of it is available immediately for someone to purchase.
Some of it is allocated to a customer already and then you've got a bunch that's coming soon. And that moves pretty rapidly each day.
The way what I would say though, is yes, we're very comfortable with the level of inventory today and that's what allows us to give the guidance that we gave for Q2. So the numbers work.
Naved Khan
Got it. And then maybe quickly on the GPU, the gross profit per unit on the e-commerce unit in Q1.
If I adjust both the fourth quarter and the first quarter for obsolescence reserve that you had in Q4 and the reversal you had in Q1, it looks like sequentially the vehicle GPU per unit actually went down. Is that the right way to look at it?
Or am I missing something? Just wanted to run it by you?
Paul Hennessy
Yes. We don't break out the components of the unit economics.
So what like I said there's more, we had to take more of an inventory reserve in the first quarter of last year because of the onset of the pandemic. So that depressed the vehicle gross profit per e-commerce unit in the prior year.
And there was we obviously didn't have that in the current year. So that's one of the factors that go into it and that combined with some efficiencies and reconditioning is what gave us the improvement and again they we don't break out all of the components of unit economics.
We just try and give you a sense as to what's driving it.
Naved Khan
Got it. Thank you.
