Thanks, Paul. Good afternoon, everyone. Ecommerce units grew 18% sequentially in Q2 to just over 18,000 units and grew over 170% year-over-year. We drove strong unit growth by matching robust consumer demand with increasing levels of available inventory at a faster clip. As Paul mentioned, at the end of the quarter, we had nearly 13,700 listed vehicles on our website, up 21% from first quarter levels. Around 40% of that inventory was available for sale, up from about 35% in Q1 as we work to meet demand. We are confident we've planned capacity to meet our medium-term unit sales goals, and we're working hard with our third-party reconditioning partners to increase the velocity of our throughput and to get our listed inventory to a level that can provide upside to our unit sales targets. Our reconditioning capacity continues to scale. As Paul mentioned, we opened 5 new third-party VRCs in the second quarter, bringing us to a total of 29 locations across the country. That puts us ahead of our schedule on our 2021 goal of up to 30 VRCs that we've discussed previously. We delivered faster inventory turns this quarter with ecommerce days to sale of 68 versus 83 in the first quarter and within our target range. Our inventory efficiency accelerated every month of the quarter as we lean further into consumer-sourced vehicles, which typically turn faster. We also benefited from our ongoing national brand and performance marketing initiatives with higher viewership on our website and increasing brand awareness. Looking into the third quarter, we expect sales of 20,000 to 20,500 ecommerce units, implying 130% year-over-year growth at the midpoint. This implies 11% sequential growth at the midpoint as we capitalize on our operational strengths, while balancing our profitability targets and what we expect to be a normalizing retail market. We expect ecommerce average selling price to remain higher year-over-year as market prices continue to trend above 2020 levels. Turning back to results, Ecommerce revenue grew 37% sequentially to nearly $580 million or up nearly 230% year-over-year. Of course, comparisons to the prior year are not as meaningful as the prior year's quarter was significantly affected by our response to the onset of the COVID pandemic. Ecommerce gross profit per unit reached $2,718, 32% higher than in Q1. Digging deeper into the drivers, both vehicle and product gross profit per unit expanded sequentially. Vehicle gross profit per unit increased sequentially 38% or $436 per unit to nearly $1,600, primarily driven by improved sales margin from a favorable pricing environment, increased consumer-sourced vehicles and further improvements to our pricing methodologies. As a reminder, we define sales margin as the selling price of the vehicle less the purchase price. The $436 improvement in vehicle gross profit per unit quarter-over-quarter was despite a headwind of increased inventory reserves, simply as a result of our increasing inventory position. Gross -- product gross profit per unit of $1,131 also expanded $228 per unit sequentially, a 25% improvement due to increased product attachment rates and, to a lesser extent, an increase in the average loan size. For the third quarter, we expect ecommerce gross profit per unit in the range of $2,350 to $2,450 which is a 10% year-over-year gain at the midpoint. While we expect to continue building on our strategic profitability pillars, we acknowledged the used car retail pricing environment will likely provide less of a sales margin tailwind in Q3 than in Q2 as the market shows signs of normalizing. We anticipate quarter-to-quarter variability and remain confident in delivering over 200% total aggregate gross profit growth for 2021. Wholesale results were strong this quarter. Units grew 16% sequentially to just over 10,000 and wholesale gross profit per unit reached $850, up significantly from a loss of $33 in the first quarter. We're happy with the higher margins that we've had on our wholesale unit, thanks to a very robust wholesale pricing environment. As we head into the third quarter, we anticipate 9,500 to 10,500 wholesale units and per unit profitability of $50 to $100 per unit. While we continue to drive fundamental improvements in our wholesale strategy, we expect that the extraordinary pricing tailwinds in the wholesale market will moderate in Q3. Our increasing consumer sourced vehicle purchases also affect wholesale gross profit per unit. We offer customers an EV online submission of basic vehicle information to get a real-time price for their vehicle and we picked that vehicle up, site on seen. Our customers love this game-changing process, and it drives some of the highest NPS in our business. As a result, some of the vehicles that we purchased for retail sales do not wind up meeting our retail criteria and are ultimately sold in the wholesale market, which puts downward pressure on overall wholesale gross profit per unit. As we expand our last mile network and we're able to pick up a majority of our consumer-sourced vehicles with a Vroom employee and equipment, it will give us the opportunity to inspect every vehicle and make real-time adjustments to acquisition pricing. We believe there is upside to our current wholesale gross profit per unit as we scale our logistics organization over time. TDA units of 1,583 decreased 11% sequentially. As we've said in the past, our top priority is scaling our ecommerce operations, which drives transient pressure on TDA as the ecommerce business consumes local inventory. In the third quarter, we anticipate 1,550 to 1,650 units and per unit profitability of $1,650 to $1,750 per unit. On a consolidated level, for Q3, we expect $858 million to $891 million in total revenues and $51 million to $56 million in total gross profit. Operating expenses of $124 million grew 14% sequentially. As Paul mentioned, we're pleased to have a very healthy liquidity after our successful convertible note offering, and we're excited to deploy that growth capital to deliver the top line results we saw in Q2 and that we're guiding to in Q3, as well as building for the long-term future of our high-growth organization. We are making simultaneous investments in people and third-party support for the medium-term growth as well as in technology for the long-term growth. Within OpEx, compensation expense of approximately $51.8 million grew 30% sequentially as we invested heavily in our sales and sales support teams as our business rapidly expands in both selling vehicles and buying vehicles from consumers. The massive growth we've driven in consumer sourced vehicles is proving to be very beneficial to our gross profit per unit. We will continue to build the org to support those efforts for the long-term benefits of the business. Logistics expenses of $20.2 million grew 33% sequentially, driven by growth in ecommerce units and higher market rates from our third-party logistics providers. This is another area of simultaneous investments that will result in a tremendous transformation in our customer experience. And in the long term, we believe we will obtain significant leverage from an expense point of view. We are racing at building out our proprietary logistics network and very pleased that we're ahead of schedule. We launched 7 new last mile hubs in Q2, bringing our total to 25. We also delivered 26% of our ecommerce units with our last mile services, up from 16% last quarter. We are confident on hitting or exceeding our goal of 30 last mile hubs by the end of the year, which would allow us to service at least 50% of total vehicle deliveries. Our first tranche of owned line haul trucks is fully online and running, and we're also accelerating our build-out of this important piece of the logistics network. Given the acceleration in our strategy, we now expect logistics capital expenditures to be about $25 million for the full year versus our prior expectations of about $10 million. Marketing expenses decreased 21% sequentially to $23.5 million of elevated levels in Q1 when we launched our Super Bowl campaign. However, we continue to make other national and performance marketing investments that drive brand awareness. As a result, we continue to expect higher levels of marketing spend sequentially. As I mentioned, we have simultaneous investments across many areas of the business as we work on our asset-light model to build a more leverageable structure for the future. We believe our current investments are needed as we continue to deliver the huge top line growth that will ultimately get Vroom to profitability. Our third quarter guidance implies approximately $6,800 of OpEx per retail unit, which is reflective of our continued investments across the business, including investments in marketing as we build a Vroom brand as well as investments in both variable processing costs and the technology to reduce or eliminate those variable costs as we transition over time to a more digital business. We believe that level of investment will be similar through the balance of 2021. We continue to be on target to reach healthy triple-digit unit -- triple-digit ecommerce unit growth and over 200% total gross profit growth for 2021. Incorporated in our annual guidance reiteration is our expectation for units to sequentially build for both quarters in the back half of the year. Lastly, turning to our balance sheet and liquidity, we ended the quarter with nearly $1.5 billion of cash on our balance sheet and $86 million of availability on our floorplan facility. Operator, we're ready for questions now. Thank you.
