| Pay vs Performance [Table Text Block] | Pay Versus Performance The following table sets forth the compensation for our CEO and the average compensation for our other Named Executive Officers (“Other NEOs”) for 2021 and 2022 (each, a “Covered Year”), both as reported in the Summary Compensation Table (“SCT”) and with certain adjustments to reflect the “compensation actually paid” to such individuals, as calculated in accordance with rules adopted by the SEC in August 2022. “Compensation actually paid” does not reflect amounts actually realized by our CEO and Other NEOs, and may be higher or lower than the amounts, if any, that are ultimately realized by such individuals. The Compensation Committee did not consider “compensation actually paid”, as defined by the SEC, when making its executive compensation decisions for the Covered Years. Please see the Compensation Discussion and Analysis section in this proxy statement for a discussion of the Compensation Committee’s philosophy, objectives, and practices when making executive compensation decisions. The table below also provides information for each Covered Year on our cumulative total shareholder return (“TSR”) and the cumulative TSR of our peer group (with each such TSR determined for the period commencing on our initial public offering registration date on March 22, 2021 (the “IPO Registration Date”)), our net (loss) income and our Adjusted EBITDA. We selected Adjusted EBITDA as our “most important financial performance measure” used to link “compensation actually paid” to our CEO and Other NEOs to our performance for 2022, because (i) we use this measure to assess our operating performance and the operating leverage in our business and (ii) our annual performance-based bonuses for our CEO and Other NEOs for 2022 were paid out at 90% of the target level based on achieving Adjusted EBITDA loss of no more than $60 million. We define Adjusted EBITDA as net income (loss), adjusted to exclude: depreciation and amortization; stock-based compensation expense; interest (income) expense; other (income) expense, net; provision for income taxes; and other one-time, non-recurring 2 Discussion an Compensatio Value of Initial Fixed $100 Fiscal Year (1) SCT Total ($) Compensation ($) (2)(3) SCT Average ($) (4)(5) Average ($)( 3)(5) ACV Total Shareholder ($) Peer Group ($) (5) Net (loss) ($) (7) Adjusted ($) (8) 2022 3,290,813 (3,177,416 ) 1,890,377 (2,353,235 ) $ 26 $ 76 (102.2)M (56.4)M 2021 16,988,089 15,877,491 6,682,921 7,613,487 $ 60 $ 126 (78.2)M (44.1)M 1.

For purposes of the adjustments to determine “compensation actually paid”, we computed the fair value of stock option awards and RSUs in accordance with ASC Topic 718 as of the end of the relevant fiscal year, other than the fair values of equity awards that vested in the Covered Year, which are valued as of the applicable vesting date. The valuation assumptions used in the calculation of such amounts are set forth in Note 13—Stock-based Compensation in our Annual Report on Form 10-K 4. The Other NEOs for 2021 were Vikas Mehta and Michael Waterman. The Other NEOs for 2022 were William Zerella, Vikas Mehta, Leanne Fitzgerald and Michael Waterman. 5.

| Tabular List [Table Text Block] | Most Important Performance Measures for FYE 2022 The following table sets forth an unranked list of the performance measures which we view as the “most important” measures for linking “compensation actually paid” to our CEO and Other NEOs for the fiscal year ended December 31, 2022 to performance. Only two financial measures are linked to compensation under the Performance Bonus Plan. These performance metrics are the most pertinent to our business model in the dealer wholesale market, which has been susceptible to the volatile environment of the past year, because of the reduction in the total addressable market, even though we were able to grow our market share. We have seen shareholders place value on progress being made in EBITDA, and have aligned our compensation accordingly.
