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.
