Equity [Abstract]
Stockholders' Equity	NOTE 10 — STOCKHOLDERS' EQUITY Organizational Transactions Immediately prior to the IPO, Carvana Co. amended and restated its certificate of incorporation to, among other things authorize (i) 50.0 million shares of Preferred Stock, par value $0.01 per share, (ii) 500.0 million shares of Class A common stock, par value $0.001 per share, and (iii) 125.0 million shares of Class B common stock, par value $0.001 per share. On December 5, 2017, Carvana Co. amended and restated its certificate of incorporation to authorize 100,000 shares of Convertible Preferred Stock, with an initial stated value of $1,000 per share and a par value of $0.01 per share. Each share of Class A common stock generally entitles its holder to one vote on all matters to be voted on by stockholders. Each share of Class B common stock held by the Garcia Parties generally entitles its holder to ten votes on all matters to be voted on by stockholders, for so long as the Garcia Parties maintain direct or indirect beneficial ownership of at least 25% of the outstanding shares of Carvana Co.'s Class A common stock determined on an as-exchanged basis assuming that all of the Class A Units and Class B Units were exchanged for Class A common stock. All other shares of Class B common stock generally entitle their holders to one vote per share on all matters to be voted on by stockholders. Holders of Class B common stock are not entitled to receive dividends and would not be entitled to receive any distributions upon the liquidation, dissolution or winding down of the Company. Holders of Class A and Class B common stock vote together as a single class on all matters presented to stockholders for their vote or approval, except as otherwise required by applicable law. As described in Note 1 — Business Organization, Carvana Group amended and restated its LLC Agreement to, among other things, provide for two classes of common ownership interests in Carvana Group. Carvana Group’s two remaining classes of common ownership interests are Class A Units and Class B Units. Carvana Co. is required to, at all times, maintain (i) a four-to-five ratio between the number of shares of Class A common stock issued by Carvana Co. and the number of Class A Units owned by Carvana Co. (subject to certain exceptions for treasury shares and shares underlying certain convertible or exchangeable securities and subject to adjustment as set forth in the exchange agreement (the "Exchange Agreement") further discussed below, and taking into account Carvana Sub’s 0.1% ownership interest in Carvana, LLC) and (ii) a four-to-five ratio between the number of shares of Class B common stock owned by the Original LLC Unitholders and the number of Class A Units owned by the Original LLC Unitholders. The Company may issue shares of Class B common stock only to the extent necessary to maintain these ratios. Shares of Class B common stock are transferable only if an Original LLC Unitholder elects to exchange them, together with 1.25 times as many LLC Units, for consideration from the Company. Such consideration from the Company can be, at the Company's election, either shares of Class A common stock or cash. As of December 31, 2019, there were approximately 189.7 million and 4.9 million Class A Units and Class B Units (as adjusted for the participation thresholds and closing price of Class A common stock on December 31, 2019), respectively, issued and outstanding. As of December 31, 2018, there were approximately 182.3 million and 5.6 million Class A Units and Class B Units (as adjusted for the participation thresholds and closing price of Class A common stock on December 31, 2018), respectively, issued and outstanding. As discussed in Note 12 — Equity-Based Compensation, Class B Units were issued under the Company’s LLC Equity Incentive Plan through the completion of the IPO (the "LLC Equity Incentive Plan"), are subject to a participation threshold, and are earned over the requisite service period. Initial Public Offering As described in Note 1 — Business Organization, on May 3, 2017, Carvana Co. completed its IPO of 15.0 million shares of Class A common stock at a public offering price of $15.00 per share. Carvana Co. received approximately $205.8 million in proceeds, net of underwriting discounts and commissions and offering expenses. Carvana Co. used the proceeds to purchase approximately 18.8 million newly-issued LLC Units of Carvana Group at a price per unit equal to 0.8 times the initial public offering price less underwriting discounts and commissions. In connection with the IPO, Carvana Co. transferred approximately 0.2 million Class A Units to Ernest Garcia II in exchange for his 0.1% ownership interest in Carvana, LLC, a majority-owned subsidiary of Carvana Group. After the transfer Carvana Co. owned approximately 18.6 million Class A Units. The Company incurred approximately $4.9 million of legal, accounting, printing, and other professional fees directly related to the IPO, including $1.3 million incurred during 2016, of which $0.4 million were paid during 2016. Upon completion of the IPO, the total costs incurred for the IPO were charged against additional paid-in capital. Public Equity Offerings On April 30, 2018, the Company completed a follow-on offering of 6.6 million shares of its Class A common stock at a public offering price of $27.50 per share and received net proceeds from the offering of approximately $172.3 million after underwriting discounts and commissions and offering expenses. The Selling Stockholder and the Selling LLC Unitholders sold a total of approximately 6.1 million shares of Class A common stock as part of the offering. The Selling LLC Unitholders exchanged approximately 6.9 million LLC Units for approximately 5.6 million shares of Class A common stock to be sold in the offering, and to the extent such Selling LLC Unitholder held Class B common stock, the corresponding shares of Class B common stock were immediately retired by the Company. The Company did not receive any proceeds from the sale of the approximately 6.1 million shares of Class A common stock by the Selling Stockholder and the Selling LLC Unitholders. On May 24, 2019, the Company completed a follow-on offering of 4.2 million shares of the Company's Class A common stock at a public offering price of $65.00 per share and received net proceeds from the offering of approximately $258.8 million after underwriting discounts and commissions and offering expenses. As part of the offering, the Company granted the underwriters a 30-day option to purchase all or part of approximately 0.6 million additional shares of Class A common stock. On June 20, 2019, the underwriters exercised their option in full for an additional $38.9 million in proceeds after offering expenses. Exchange Agreement Carvana Co. and the LLC Unitholders entered into an Exchange Agreement under which each LLC Unitholder (and certain permitted transferees thereof) may receive shares of the Company's Class A common stock in exchange for their LLC Units on a four-to-five conversion ratio, or cash at the option of the Company, subject to conversion ratio adjustments for stock splits, stock dividends, reclassifications, and similar transactions and subject to vesting for certain Class A Units and subject to vesting and the respective participation threshold for Class B Units. To the extent such owners also hold Class B common stock, they will be required to deliver to Carvana Co. a number of shares of Class B common stock equal to the number of shares of Class A common stock being exchanged for. Any shares of Class B common stock so delivered will be canceled. The number of exchangeable Class B Units is determined based on the value of Carvana Co.'s Class A common stock and the applicable participation threshold. During the years ended December 31, 2019 and December 31, 2018, certain LLC Unitholders exchanged 5.4 million and 14.2 million LLC Units and 3.1 million and 10.3 million shares of Class B common stock for 4.3 million and 11.3 million newly-issued shares of Class A common stock, respectively. Simultaneously, and in connection with these exchanges, Carvana Co. received 5.4 million and 14.2 million LLC Units during the years ended December 31, 2019 and December 31, 2018, respectively, increasing its total ownership interest in Carvana Group, and canceled the exchanged shares of Class B common stock. Class C Redeemable Preferred Units On April 27, 2016, the Company authorized the issuance of and sold approximately 18.3 million Class C Redeemable Preferred Units for approximately $100.0 million to Ernest Garcia II. On July 12, 2016, the Company authorized the issuance of and sold approximately 8.6 million Class C Redeemable Preferred Units to CVAN Holdings, LLC, and approximately 1.7 million Class C Redeemable Preferred Units to GV Auto I, LLC for approximately $50.0 million and $9.7 million, respectively. On December 9, 2016, the Company authorized the issuance of and sold approximately 0.5 million Class C Redeemable Preferred Units to the Fidel Family Trust for approximately $2.7 million. The Company recorded the issuance and sale of Class C Redeemable Preferred Units at fair value, net of issuance costs. In accordance with the Company’s Operating Agreement, the Class C Redeemable Preferred Units accrued a return (the "Class C Return") at a coupon rate of 12.5% compounding annually on the aggregate amount of capital contributions made with respect to the Class C Redeemable Preferred Units. On May 3, 2017, the Company closed its IPO at a price such that the Company is no longer liable for the accrued Class C Return, and the 43.1 million outstanding Class C Redeemable Preferred Units converted to Class A Units on a one-to-one basis and the related balance became a component of permanent equity on the accompanying consolidated balance sheet. Convertible Preferred Stock On December 5, 2017, Carvana Co. sold 100,000 shares of Convertible Preferred Stock for a purchase price of $100.0 million and net proceeds of approximately $98.5 million, which it used to purchase 100,000 Convertible Preferred Units of Carvana Group at a price per unit equal to the initial stated value of the Convertible Preferred Stock less issuance costs. The Convertible Preferred Stock has a par value of $0.01 per share and a liquidation value of $1,000 per share. At the holder's request beginning on January 29, 2018, any or all shares of the Convertible Preferred Stock were convertible into shares of Class A common stock at an initial conversion rate of 50.78 shares of Class A common stock per share of Convertible Preferred Stock. On or after December 5, 2018, the Company had the option to cause all shares of Convertible Preferred Shares to be converted into shares of Class A common stock or cash, at the Company's election, if the 10-day volume-weighted average price equaled or exceeded 150% of the conversion price as set forth in the agreement. In the event Carvana Co. issued any shares of Class A common stock upon conversion of any shares of Convertible Preferred Stock or in connection with any change of control repurchase of shares of Convertible Preferred Stock, a corresponding number of Convertible Preferred Units would be canceled and cease to be outstanding, and Carvana Group would issue Class A Units to Carvana Co. on a four-to-five ratio between the number of shares of Class A common stock issued by Carvana Co. to the holders of the Convertible Preferred Stock and the number of Class A Units issued. During the year ended December 31, 2018, at the holder's request 75,000 shares of Convertible Preferred Stock, and at the Company's election 25,000 shares of Convertible Preferred Stock, were converted into a total of approximately 5.1 million shares of Class A common stock. Simultaneously, and in connection with these conversions, 100,000 Convertible Preferred Units were canceled and Carvana Group issued approximately 6.3 million Class A Units to Carvana Co. The initial conversion price was $19.6945, which was calculated based on a 20.0% premium to the volume weighted average price for Class A common stock during the 5 trading days immediately preceding December 4, 2017. Following announcement of the transaction, the share price of Class A common stock increased and exceeded the conversion price on the commitment date and resulted in a beneficial conversion feature ("BCF") of approximately $2.6 million. The BCF was originally recorded as a reduction of the Convertible Preferred Stock with an offset to additional paid-in capital. The BCF accreted as a deemed dividend through January 29, 2018, the first available conversion date, increasing the carrying value of the Convertible Preferred Stock with an offsetting charge to additional paid-in capital. During the year ended December 31, 2018, the Company recorded approximately $1.4 million in accretion related to the BCF. Upon a change of control, as defined in the agreement, any holder of Convertible Preferred Stock had the option to require the Company (or its successor) to purchase, any or all of its Convertible Preferred Stock at a purchase price per share, payable at the Company’s option in any combination of cash or shares of Class A common stock, of 101% of the liquidation preference, plus all accumulated dividends. Holders of the Convertible Preferred Stock had no voting rights. The Convertible Preferred Stock ranked senior, as to payment of dividends and distributions of assets upon the liquidation, dissolution or winding up of Company, to the Company’s common stock and any shares of capital stock of the Company not expressly ranking senior to or pari passu with the Convertible Preferred Stock, and junior to all shares of capital stock of the Company issued after the issuance of the Convertible Preferred Stock, if the terms of which expressly provided that such shares would rank senior to the Convertible Preferred Stock. The Convertible Preferred Stock accrued dividends at 5.5% per annum of the liquidation preference of $1,000 per share. The dividends were payable in cash quarterly commencing March 15, 2018 so long as the Company had funds legally available and the Board declared a cash dividend payable. The Company could not declare dividends on shares of its common stock or purchase or redeem shares of its common stock, unless all accumulated and unpaid dividends on the Convertible Preferred Stock had been paid in full or a sum for such amounts had been set aside for payment. As the Company declared and paid dividends on the Convertible Preferred Stock, Carvana Group made distributions to Carvana Co. with respect to the Convertible Preferred Units in an amount equal to the related Convertible Preferred Stock dividend amount and any corresponding tax payments. During the year ended December 31, 2018, the Company paid approximately $4.6 million of dividends to the holders of the Convertible Preferred Stock and Carvana Group distributed approximately $4.6 million to Carvana Co. with respect to the Convertible Preferred Units. As of December 31, 2018, there were no outstanding shares of Convertible Preferred Stock and no related accrued dividends. Class A Non-Convertible Preferred Units On October 2, 2018, Carvana Group amended its LLC Agreement to create a class of non-convertible preferred units (the "Class A Non-Convertible Preferred Units"), effective September 21, 2018. The Class A Non-Convertible Preferred Units were created in connection with Carvana Co.'s issuance of the Senior Notes in September 2018 and May 2019, as discussed further in Note 9 — Debt Instruments. Carvana Co. used its net proceeds from the Senior Notes to purchase 600,000 Class A Non-Convertible Preferred Units. In the event Carvana Co. makes payments on the Senior Notes, Carvana Group will make an equal cash distribution, as necessary, to the Class A Non-Convertible Preferred Units. For each $1,000 principal amount of Senior Notes that Carvana Co. repays or otherwise retires, one Class A Non-Convertible Preferred Unit shall be canceled and retired. Contributions of Class A Common Shares From Ernest Garcia III During the years ended December 31, 2019 and 2018, the Company and its Chief Executive Officer, Ernest Garcia III, entered into contribution agreements (the "Contribution Agreements") in connection with the 100k Milestone Gift, as defined in Note 6 — Related Party Transactions. Pursuant to the Contribution Agreements, Mr. Garcia contributed approximately 0.2 million shares during both of the years ended December 31, 2019 and 2018 of the Company's Class A common stock to the Company, at no charge. The Company subsequently granted approximately 0.2 million restricted stock units during both of the years ended December 31, 2019 and 2018 to employees. Refer to Note 12 — Equity-Based Compensation for further discussion. Although the Company does not expect Mr. Garcia to incur any tax obligations related to the Share Contributions, it has indemnified Mr. Garcia from any such obligations that may arise.

Immediately prior to the IPO, Carvana Co. amended and restated its certificate of incorporation to, among other things authorize (i) 50.0 million shares of Preferred Stock, par value $0.01 per share, (ii) 500.0 million shares of Class A common stock, par value $0.001 per share, and (iii) 125.0 million shares of Class B common stock, par value $0.001 per share.

Each share of Class A common stock generally entitles its holder to one vote on all matters to be voted on by stockholders. Each share of Class B common stock held by the Garcia Parties generally entitles its holder to ten votes on all matters to be voted on by stockholders, for so long as the Garcia Parties maintain direct or indirect beneficial ownership of at least 25% of the outstanding shares of Carvana Co.'s Class A common stock determined on an as-exchanged basis assuming that all of the Class A Units and Class B Units were exchanged for Class A common stock. All other shares of Class B common stock generally entitle their holders to one vote per share on all matters to be voted on by stockholders. Holders of Class B common stock are not entitled to receive dividends and would not be entitled to receive any distributions upon the liquidation, dissolution or winding down of the Company. Holders of Class A and Class B common stock vote together as a single class on all matters presented to stockholders for their vote or approval, except as otherwise required by applicable law.

As described in Note 1 — Business Organization, Carvana Group amended and restated its LLC Agreement to, among other things, provide for two classes of common ownership interests in Carvana Group. Carvana Group’s two remaining classes of common ownership interests are Class A Units and Class B Units. Carvana Co. is required to, at all times, maintain (i) a four-to-five ratio between the number of shares of Class A common stock issued by Carvana Co. and the number of Class A Units owned by Carvana Co. (subject to certain exceptions for treasury shares and shares underlying certain convertible or exchangeable securities and subject to adjustment as set forth in the exchange agreement (the "Exchange Agreement") further discussed below, and taking into account Carvana Sub’s 0.1% ownership interest in Carvana, LLC) and (ii) a four-to-five ratio between the number of shares of Class B common stock owned by the Original LLC Unitholders and the number of Class A Units owned by the Original LLC Unitholders. The Company may issue shares of Class B common stock only to the extent necessary to maintain these ratios. Shares of Class B common stock are transferable only if an Original LLC Unitholder elects to exchange them, together with 1.25 times as many LLC Units, for consideration from the Company. Such consideration from the Company can be, at the Company's election, either shares of Class A common stock or cash.

As of December 31, 2019, there were approximately 189.7 million and 4.9 million Class A Units and Class B Units (as adjusted for the participation thresholds and closing price of Class A common stock on December 31, 2019), respectively, issued and outstanding. As of December 31, 2018, there were approximately 182.3 million and 5.6 million Class A Units and Class B Units (as adjusted for the participation thresholds and closing price of Class A common stock on December 31, 2018), respectively, issued and outstanding.

As described in Note 1 — Business Organization, on May 3, 2017, Carvana Co. completed its IPO of 15.0 million shares of Class A common stock at a public offering price of $15.00 per share. Carvana Co. received approximately $205.8 million in proceeds, net of underwriting discounts and commissions and offering expenses. Carvana Co. used the proceeds to purchase approximately 18.8 million newly-issued LLC Units of Carvana Group at a price per unit equal to 0.8 times the initial public offering price less underwriting discounts and commissions. In connection with the IPO, Carvana Co. transferred approximately 0.2 million Class A Units to Ernest Garcia II in exchange for his 0.1% ownership interest in Carvana, LLC, a majority-owned subsidiary of Carvana Group. After the transfer Carvana Co. owned approximately 18.6 million Class A Units.

The Company incurred approximately $4.9 million of legal, accounting, printing, and other professional fees directly related to the IPO, including $1.3 million incurred during 2016, of which $0.4 million were paid during 2016. Upon completion of the IPO, the total costs incurred for the IPO were charged against additional paid-in capital.

The Selling Stockholder and the Selling LLC Unitholders sold a total of approximately 6.1 million shares of Class A common stock as part of the offering. The Selling LLC Unitholders exchanged approximately 6.9 million LLC Units for approximately 5.6 million shares of Class A common stock to be sold in the offering, and to the extent such Selling LLC Unitholder held Class B common stock, the corresponding shares of Class B common stock were immediately retired by the Company.

To the extent such owners also hold Class B common stock, they will be required to deliver to Carvana Co. a number of shares of Class B common stock equal to the number of shares of Class A common stock being exchanged for. Any shares of Class B common stock so delivered will be canceled.

During the years ended December 31, 2019 and December 31, 2018, certain LLC Unitholders exchanged 5.4 million and 14.2 million LLC Units and 3.1 million and 10.3 million shares of Class B common stock for 4.3 million and 11.3 million newly-issued shares of Class A common stock, respectively.

On December 5, 2017, Carvana Co. sold 100,000 shares of Convertible Preferred Stock for a purchase price of $100.0 million and net proceeds of approximately $98.5 million, which it used to purchase 100,000 Convertible Preferred Units of Carvana Group at a price per unit equal to the initial stated value of the Convertible Preferred Stock less issuance costs.

During the years ended December 31, 2019 and 2018, the Company and its Chief Executive Officer, Ernest Garcia III, entered into contribution agreements (the "Contribution Agreements") in connection with the 100k Milestone Gift, as defined in Note 6 — Related Party Transactions. Pursuant to the Contribution Agreements, Mr. Garcia contributed approximately 0.2 million shares during both of the years ended December 31, 2019 and 2018 of the Company's Class A common stock to the Company, at no charge. The Company subsequently granted approximately 0.2 million restricted stock units during both of the
