Check the appropriate box below if the Form 8-K filing is intended to simultaneously satisfy the filing obligation of the registrant under any of the following provisions (see General Instruction A.2.):

The information provided under “Recent Financial Results” in Item 7.01 below is hereby incorporated by reference into this Item 2.02.

The information furnished under Item 2.02 of this Current Report shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933, except as shall be expressly set forth by specific reference in such filing.

On April 22, 2013, DriveTime Automotive Group, Inc. (“DTAG”) and DT Acceptance Corporation (“DTAC” and, together with DTAG, the “Issuers”) commenced a private offering (the “Offering”) under Rule 144A and Regulation S of the Securities Act of 1933, as amended, of $50 million aggregate principal amount of 12.625% senior secured notes due 2017 (the “Notes”) to qualified institutional buyers inside the United States and to certain non-U.S. persons located outside the United States.

The Notes will be additional notes issued under an indenture executed on June 4, 2010. On that date, the Issuers issued and sold $200.0 million of 12.625% Senior Secured Notes due 2017 (the “Initial Notes”). The Additional Notes will have substantially identical terms and will constitute part of the same series as the Initial Notes.

The Issuers intend to use the proceeds from the Offering to reduce outstanding borrowings under their existing warehouse facilities, after paying estimated fees and expenses.

Recent Financial Results

In connection with the private offering of the Notes, the Issuers distributed a confidential preliminary offering memorandum related to the Notes (the “Offering Memorandum”) to eligible prospective investors on April 22, 2013. The Offering Memorandum included preliminary financial results of the Issuers and their subsidiaries (together, “DriveTime” or “we”) for the fiscal quarter ended March 31, 2013, as follows, which is excerpted from the Offering Memorandum:

The following are preliminary estimates of selected consolidated financial data for the three months ended March 31, 2013:

We attribute the estimated decrease in first quarter Adjusted EBITDA primarily to (i) IRS delays in processing income tax refunds, causing a negative impact on the seasonal buying patterns of our

customers; (ii) higher net charge-offs related to loan performance and lower recovery rates on repossessed vehicles due to a decline in wholesale auction values; (iii) higher retail operating expenses from new dealership openings in the second half of 2012; and (iv) the effects of deferred service contract revenue in regions where we recently began offering our limited warranty as a separately priced service contract. Excluding the effects of deferred service contract revenue, we expect that Adjusted EBITDA would have ranged from $45 to $47 million for our first quarter ended March 31, 2013, and total revenue would have been approximately $390 million for the first quarter 2013.

We have historically included our DriveCare^® limited warranty as part of the bundled retail price of each vehicle we sell, recognizing revenue and costs related to the warranty at the time of the sale. Beginning in the fourth quarter of 2012, however, we began offering our DriveCare^® limited warranty as a separately priced unbundled service contract in our dealerships located in Tennessee, Virginia and Ohio and, subsequent to December 31, 2012, expanded this offering to California. The revenue and costs related to these unbundled service contracts is deferred and recognized over the life of the service contract instead of at the time of the sale of the vehicle. Expansion of the regions in which we offer unbundled service contracts will negatively impact our gross revenue, gross margin, and net income in future periods when compared to historical results due to the revenue deferral associated with unbundling. However, we do not expect the economic and cash flow impact of unbundling to have a negative effect on our overall financial position or liquidity.

We have provided only estimates of the preliminary results described above because our financial closing procedures and quarterly review for our first quarter ended March 31, 2013 are not yet complete. Though we expect that our final results will be approximately as described above, the estimates provided represent the most current information available to management, and certain estimates have not been finalized. Therefore, it is possible that our actual results may differ materially from our current estimates and that other developments and information may arise between now and the time our financial results for our first quarter ended March 31, 2013 are finalized.

Accordingly, you should not place undue reliance on these estimates. The preliminary financial data for our first quarter ended March 31, 2013 has been prepared by, and is the responsibility of, our management, and has not been reviewed, audited, or subjected to any other procedures by our independent registered public accounting firm. Accordingly, our independent registered public accounting firm does not express an opinion or any other form of assurance with respect to this preliminary financial data.

This Current Report on Form 8-K does not constitute an offer to sell, or a solicitation of an offer to buy the Notes, or any security, and shall not constitute an offer, solicitation or sale in any jurisdiction in which such offering would be unlawful.

Consummation of the Offering is subject to a number of market and other conditions. No assurance can be given that any such refinancing can or will be completed on terms that are acceptable to the Issuers, if at all.
