Accounting Policies [Abstract]
Summary of Significant Accounting Policies	NOTE 2 — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The accompanying interim unaudited condensed consolidated financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information. All intercompany balances and transactions have been eliminated. Certain information and footnote disclosures normally included in annual financial statements have been condensed or omitted. The Company believes the disclosures made are adequate to prevent the information presented from being misleading. However, the accompanying unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements as of and for the year ended December 31, 2016 included in the final prospectus for Carvana Co.’s IPO filed April 28, 2017 pursuant to Rule 424(b) under the Securities Act of 1933, as amended, with the SEC. The accompanying unaudited condensed consolidated financial statements reflect all adjustments (consisting only of normal and recurring items) necessary to present fairly the Company’s financial position as of June 30, 2017, its results of operations for the three and six months ended June 30, 2017 and 2016, its cash flows for the six months ended June 30, 2017 and 2016, and the changes in its stockholders' equity for the six months ended June 30, 2017. The Company discloses all material changes in its members’ equity for the six months ended June 30, 2016 throughout the accompanying notes, and, therefore, does not separately present a statement of changes in members’ equity for this period in its unaudited condensed consolidated financial statements. Interim results are not necessarily indicative of full year performance because of the impact of seasonal and short-term variations. As discussed in Note 1 — Business Organization, Carvana Group is considered a VIE and Carvana Co. consolidates its financial results due to the determination that it is the primary beneficiary. The Company reviews subsidiaries and affiliates, as well as other entities, to determine if it should be considered variable interest entities, and whether it should change the consolidation determinations based on changes in its characteristics. The Company considers an entity a VIE if its equity investors own an interest therein that lacks the characteristics of a controlling financial interest or if such investors do not have sufficient equity at risk for the entity to finance its activities without additional subordinated financial support or if the entity is structured with non-substantive voting interests. To determine whether or not the entity is consolidated with the Company’s results, the Company also evaluates which interests are variable interests in the VIE and which party is the primary beneficiary of the VIE. Liquidity The accompanying interim unaudited condensed consolidated financial statements of the Company have been prepared in conformity with U.S. GAAP, which contemplate continuation of the Company as a going concern. From inception, the Company has funded operations through the sale of Class A Units, its IPO completed on May 3, 2017 for net proceeds of approximately $205.9 million, the sale of Class C Redeemable Preferred Units, capital contributions from DriveTime and short-term funding from the Company’s majority owner. The Company has historically funded vehicle inventory purchases through its Floor Plan Facility, described in further detail in Note 7 — Debt Instruments, and has approximately $33.2 million available under the Floor Plan Facility to fund future vehicle inventory purchases as of June 30, 2017. Management believes that current working capital is sufficient to fund operations for at least one year from the financial statement issuance date. Use of Estimates The preparation of these consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions. Certain accounting estimates involve significant judgments, assumptions and estimates by management that have a material impact on the carrying value of certain assets and liabilities, disclosures of contingent assets and liabilities and the reported amounts of revenues and expenses during the reporting period, which management considers to be critical accounting estimates. The judgments, assumptions and estimates used by management are based on historical experience, management’s experience and other factors, which are believed to be reasonable under the circumstances. Because of the nature of the judgments and assumptions made by management, actual results could differ materially from these judgments and estimates, which could have a material impact on the carrying values of the Company’s assets and liabilities and the results of operations. Comprehensive Loss During the three and six months ended June 30, 2017 and 2016, the Company did not have any other comprehensive income and, therefore, the net loss and comprehensive loss were the same for all periods presented. Restricted Cash The restricted cash includes the deposit required under the Company's Floor Plan Facility, which is 5% of the outstanding floor plan facility principal balance, as explained in Note 7 — Debt Instruments and amounts held as restricted cash as required under letter of credit agreements, as explained in Note 13 — Commitments and Contingencies. Income Taxes The Company accounts for income taxes pursuant to the asset and liability method which requires the recognition of deferred income tax assets and liabilities related to the expected future tax consequences arising from temporary differences between the carrying amounts and tax bases of assets and liabilities based on enacted statutory tax rates applicable to the periods in which the temporary differences are expected to reverse. Any effects of changes in income tax rates or laws are included in income tax expense in the period of enactment. A valuation allowance is recognized if the Company determines it is more likely than not that all or a portion of a deferred tax asset will not be recognized. Adoption of New Accounting Standards In October 2016, the FASB issued ASU 2016-17, Interests Held through Related Parties That Are Under Common Control ("ASU 2016-17"), which updates the consolidation requirements when evaluating whether or not the entity is the primary beneficiary of a VIE with regard to interests held by related parties under common control. Under ASU 2016-17, entities will consider all indirect economic interests in a VIE held by related parties on a proportionate basis regardless of whether or not the related parties are under common control. The update is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2016, with early adoption permitted. Since the Company has adopted ASU 2015-02, ASU 2016-17 requires retrospective application to all periods presented. The Company adopted ASU 2016-17 on January 1, 2017 and it did not have an impact on its consolidated financial statements. In January 2017, the FASB issued ASU 2017-01, Business Combinations ("ASU 2017-01"), which narrows the definition of a business and assists entities evaluate whether transactions should be accounted for as acquisitions of assets or businesses. Under ASU 2017-01, when substantially all the fair value of the gross assets acquired is concentrated in a single identifiable asset or a group of similar identifiable assets, the set is not a business. If the screen is not met, entities must consider a robust framework to determine when a set of assets and activities is a business. The update is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2017, with early adoption permitted. The Company adopted ASU 2017-01 on January 1, 2017 and it did not have a material impact on its consolidated financial statements. Accounting Standards Issued But Not Yet Adopted Since May 2014, the FASB has issued several accounting standards updates related to revenue recognition including ASC 606, Revenue from Contracts with Customers, which amends the guidance in ASC 605, Revenue Recognition, and provides a single, comprehensive revenue recognition model for all contracts with customers. These updates contain principles that an entity will apply to determine the measurement of revenue and timing of when it is recognized. The entity will recognize revenue to reflect the transfer of goods or services to customers at an amount that the entity expects to be entitled to in exchange for those goods or services. The updates address how entities should identify goods and services being provided to a customer, the unit of account for a principal versus agent assessment, how to evaluate whether a good or service is controlled before being transferred to a customer and how to assess whether an entity controls services performed by another party. These updates are effective for fiscal years, and interim periods within those years, beginning after December 15, 2017 with early adoption permitted. The Company currently plans to adopt these updates for the fiscal year beginning January 1, 2018 and is evaluating its transition method. Based on the manner in which the Company recognizes revenue, the Company does not anticipate a material impact on its consolidated financial statements as a result of adopting these updates. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) (“ASU 2016-02”) related to the accounting for leases. This ASU introduces a lessee model that requires a right-of-use asset and lease obligation to be presented on the balance sheet for all leases, whether operating or financing. The ASU eliminates the requirement in current U.S. GAAP for an entity to use bright-line tests in determining lease classification. Expense recognition on the income statement remains similar to current lease accounting guidance. The ASU is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2018. The Company plans to adopt this ASU for its fiscal year beginning January 1, 2019. The adoption of this ASU will require the recognition of a right-of-use asset and a lease obligation for the Company’s leases (see Note 13 — Commitments and Contingencies).

NOTE 2 — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The accompanying interim unaudited condensed consolidated financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information. All intercompany balances and transactions have been eliminated. Certain information and footnote disclosures normally included in annual financial statements have been condensed or omitted. The Company believes the disclosures made are adequate to prevent the information presented from being misleading.
