Thanks Paul. It's great to be a member of the pit crew at Vroom, and to join everyone for the third quarter earnings call. I would like to begin on Slide 12 with our financial highlights. We had a strong quarter as we drove healthy year-over-year unit growth, and outperformed our expectations for the quarter on revenue, e-commerce gross profit per unit, total gross profit, and adjusted EBITDA. Total revenues of $897 million increased nearly 180 % year-over-year and 18 % sequentially, coming in above the high end of our guidance. Our overall growth was principally driven by growth in retail units. Higher than expected average selling prices further drove the outperformance relative to our expectations. Third quarter e-commerce units of $19,683 grew 123 % year-over-year and 8 % quarter-over-quarter. We experienced healthy growth for the quarter as consumer demand remains high for used vehicles, and as we delivered strong execution in a healthy demand environment. During the quarter, continued focus on our strategic objectives drove increased listed inventory in amplified marketing. Our e-commerce GPPU hit $2560 up 17 % year-over-year, and meaningfully higher product GPPU, and slightly increased vehicle GPPU. Further into the drivers of e-commerce units and e-commerce performance on the next slide. Full gross profit for the quarter of $58 million increased 128 % year-over-year, and came in ahead of our expectations. This was driven primarily by the expansion of e-commerce GPPU in higher unit volumes. As expected, our per unit profitability contracted versus the second quarter as we experienced transient macro headwinds to sales margins. Despite the headwinds, we surpassed our gross profit guidance for the quarter, thanks to better-than-anticipated performance, across all 3 lines of our business. EBITDA, which was adjusted for acquisition costs related to our announced UACC transaction, came in at an $87 million loss versus a $36 million loss in the prior year. This was also ahead of our expectations for the quarter. Third quarter adjusted loss per share of $0.70, was better than our guidance due to improved revenues, gross profit, and expense levels. At the bottom of Page 12, you can see the primary highlights of our fourth quarter outlook. For more details regarding our fourth quarter guidance, please see our earnings press release. We're expecting 20,000 to 20,500 e-commerce units in the fourth quarter. This implies 84 % year-over-year growth at the midpoint. As Paul mentioned, we are experiencing transitory events that are reducing throughput in our supply chain. As a result of these temporary issues, we anticipate total revenues of $865 million to $900 million. A year-over-year midpoint increase of 117 %. Primarily driven by unit growth and current elevated average selling prices. We expect ecommerce gross profit per unit in the range of $2100 to $2300. Supplies 21 % year-over-year growth at the midpoint. We are guiding to a total gross profit of $50 to $58 million, primarily driven by our annual growth in e-commerce units and GPPU. We remain focused on achieving over 200 % gross profit growth for 2021. Slide 13, provides the summary of our third quarter e-commerce performance. As we've discussed previously on today's call, our e-commerce units grew 123 % year-over-year. It came in slightly below our expectations. E-commerce revenues hit $702 million, an increase of 216 % year-over-year, driven by strong unit growth and higher average selling prices. Our third-quarter e-commerce average selling price of approximately $34,400 expanded significantly year-over-year and was higher than our guided range as we continue to improve our pricing algorithm in a historically strong vehicle pricing market. - Ecommerce vehicle GPPU of $1,315 increased slightly from $1,302 in the prior year. During the quarter, we continued to deliver improved productivity on reconditioning costs, which was partially offset by lower sales margins as the cost to acquire vehicles in the current environment were higher than the prior year. E-commerce product GPPU of $1,245 increased $359 or 41 % from $886 a year ago. It also showed quarter-over-quarter gains. Our higher product profitability was primarily driven by higher attachment rates, as well as higher average loan sizes due to higher e-commerce average selling prices. Moving to the other segments on Slide 14. Wholesale units of $9,760 grew 58 % year-over-year. Wholesale gross profit per unit of $215, contracted year-over-year as expected and came in ahead of our guidance of $50 to $100. As our pricing strategies kept pace with increasing prices in the used vehicle market through the quarter, we were able to book higher gross profit on wholesale units than we originally anticipated. We sold 1,749 TDA units in the third quarter, growing 20 % year-over-year, and surpassing our expectations. We saw positive customer response to our inventory selection improvements for TDA. TDA GPPU also increased to $2,175 for the quarter, up $347 over the prior year, and well ahead of our guidance range of $1650 to $1750. TDA GPPU benefited from lower per unit sourcing costs year-over-year, as well as higher product profit, due to higher average loan balances. Turning to Slide 15. I would like to provide some additional color on our SG&A performance. On an absolute spend basis, our SG&A increased as we continue to make key strategic investments in staffing and new technology, to keep pace with demand as Paul discussed earlier in his comments. The chart on Slide 15 shows our SG&A spend per total ecommerce transaction year-to-date, for 2021 versus 2020. For 2020, our total SG&A spend per total e-commerce transaction was $5,401. Year-over-year increases in logistics rate inflation and expenses related to the announcement of the acquisition of UACC at $169 per unit on a year-to-date basis. A total e-commerce transactions, which we defined as e-commerce vehicle purchases, plus e-commerce units sold has more than tripled year-to-date versus 2020. Purchases include trade-ins and straight buys and exclude auction source units. Despite the increase in logistics and transaction expenses, we are seeing the benefit of leveraging our sale by reducing per unit cost by $1,617 year-over-year. On a net basis, this benefit resulted in a 27 % reduction to our year-to-date SG&A per total e-commerce transaction versus 2020. In closing on Slide 16, I am pleased with our performance during the third quarter. We are working tirelessly to continue executing our growth strategy. Our fourth quarter guidance continues our track record of strong year-over-year growth. And we are looking forward to closing the UACC acquisition and welcoming their team as partners in the future growth of our Company. We are excited to share with you the transformational aspect of the UACC acquisition, and will do so after the transaction closes late this year or early in 2022. Thank you for your time, everyone. It is great to be at Vroom. With that, Paul and I are ready for your questions.
