Onyx Acceptance Corporation 401(k) Savings Plan Dated: June 29, 2005 By: /s/ DON DUFFY ------------------------------------ Don Duffy Executive Vice President, Chief Financial Officer and Director TABLE OF CONTENTS PAGE NUMBER ------ Report of Independent Registered Public Accounting Firm 1 Statements of Net Assets Available for Plan Benefits - December 31, 2004 and 2003 2 Statements of Changes in Net Assets Available for Plan Benefits -Years Ended December 31, 2004 and 2003 3 Notes to Financial Statements - December 31, 2004 and 2003 4 - 8 Supplementary Information: Schedule 1: Schedule of Assets Held for Investment Purposes at End of Year - December 31, 2004 9 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM Participants and Trustees Onyx Acceptance Corporation 401(k) Savings Plan We have audited the accompanying statements of net assets available for plan benefits and the related statements of changes in net assets available for plan benefits of the Onyx Acceptance Corporation 401(k) Savings Plan (the Plan), as of and for the years ended December 31, 2004 and 2003. These financial statements are the responsibility of the Plan's management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits in accordance with generally accepted auditing standards and standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audit included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion of the effectiveness of Company's internal control over financial reporting. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements referred to above present fairly, in all material respects, the net assets available for plan benefits and the changes in net assets available for plan benefits as of and for the years ended December 31, 2004 and 2003, in conformity with accounting principles generally accepted in the United States of America. Our audits were performed for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental schedule of assets held for investment purposes is presented for the purpose of additional analysis and is not a required part of the basic financial statements but is supplementary information required by the Department of Labor's Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. This supplemental schedule is the responsibility of the Plan's management. The supplemental schedule has been subjected to the auditing procedures applied in the audit of the basic financial statements for the year ended December 31, 2004, and, in our opinion, is fairly stated in all material respects in relation to the basic financial statements taken as a whole. As described in Note 10, the plan sponsor completed a plan of merger with Capital One Auto Finance, Inc.

Participants should refer to the Plan agreement for a more complete description of the Plan's provisions. GENERAL - The Plan is a defined contribution plan covering substantially all of the employees of Onyx Acceptance Corporation and Subsidiaries (the Company) who have completed six months of eligibility service and are at least 21 years old. The Plan is designed to comply with Section 401(a) of the Internal Revenue Code as a defined contribution plan. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974. The assets of the Plan are held and invested by the TruSource Division of Union Bank of California (TruSource), formerly CNA Trust Company, acting as trustee, custodian and recordkeeper. ELIGIBILITY - Employees are eligible to enter the Plan following the completion of the sixth month of employment with the Company, and the employee has reached his or her 21st birthday. CONTRIBUTIONS AND WITHDRAWALS - Contributions are made to the Plan by means of a salary deferral agreement under which the participant is entitled to defer up to the lesser of 20 percent of their eligible compensation or a fixed amount determined annually by the Internal Revenue Service. The Company can make a discretionary matching contribution annually to participants. Currently, the Company's potential match is up to 50 percent of participant contributions up to the first 6 percent of eligible contributions depending upon the years of service, subject to approval annually by the Board of Directors. For the years ended December 31, 2004 and 2003, the Company made matching contributions of $650,318 and $473,564, respectively. The Company may also make discretionary profit sharing contributions under the Plan. The Company made no discretionary profit sharing contributions to the Plan for the years ended December 31, 2004 and 2003. Participants in service may make hardship withdrawals from their accounts upon demonstrating immediate and heavy financial need as defined by provisions of the Internal Revenue Code ("IRC"). VESTING - Participants are vested on their contributions plus earnings, immediately. Vesting in the Company's matching contribution is based on years of service. A year of vesting service is defined as any period in which a participant completes 365 days of service. The following schedule describes the vesting percentages for participants: YEARS OF SERVICE VESTED BENEFIT PERCENTAGE ---------------- ------------------------- 1 year but less than 2 ........... 20% 2 years but less than 3 ........... 40% 3 years but less than 4 ........... 60% 4 years but less than 5 ........... 80% 5 years or more ................... 100% PARTICIPANT ACCOUNTS - Each participant account is credited with the participant's contribution and an allocation of (a) the Company's matching contribution, (b) any Company discretionary contribution, and (c) Plan net earnings which include an allocation of certain administrative expenses. Allocations of matching contributions are based on participant contributions, as defined. Allocations of discretionary contributions are based on participant directed investment decisions. Allocations of Plan earnings and administrative expenses, when applicable, are based on participant account balances. The benefit to which a participant is entitled is the benefit that can be provided from the participant's vested interest in their account balance. PAYMENT OF BENEFITS - Upon termination of service before the normal retirement age of 65, a participant with benefits of over $5,000 may elect to defer distribution until normal retirement age or receive a lump sum payment equal to the vested share of the participant's account. 4 ONYX ACCEPTANCE CORPORATION 401(K) SAVINGS PLAN NOTES TO FINANCIAL STATEMENTS (CONTINUED) DECEMBER 31, 2004 AND 2003 NOTE 1 - DESCRIPTION OF PLAN (CONTINUED) Upon termination of service at the normal retirement age of 65, a participant may elect to receive a lump-sum payment equal to the vested value of his or her account. Benefits may also be accessed in the event of disability or death. The Plan allows participants to make early withdrawals for certain financial hardships. The Plan also allows in-service withdrawals by participants after they reach age 59-1/2. Participants age 59-1/2 taking in-service withdrawals will be required to pay all applicable taxes on the withdrawals but will not be subject to penalty taxes for early withdrawals. PARTICIPANT LOANS - Participants may borrow 50 percent of their vested account balance up to $50,000 at the prime rate plus 1 percent (an aggregate of 6.00% and 5.00% at December 31, 2004 and 2003, respectively), with payment of principal and interest made through payroll deductions. A general loan will have a term of 5 years or less. Home loans can be repaid over a reasonable period of time that may exceed 5 years. The loans are secured by the balance in the participant's account. Participant loans are stated at the unpaid principal value, which are estimated to approximate fair value. ADMINISTRATIVE EXPENSE - Administrative expense, other than certain miscellaneous charges by the Trustee, have to date been paid for by the Company on behalf of the Plan. Payments of administrative expenses on behalf of the Plan constitute exempt party-in-interest transactions, and are not reflected in the Statement of Changes in Net Assets Available for Plan Benefits. FORFEITURES - Forfeitures of unvested Plan assets are used to reduce the Company's contributions and costs of administering the Plan. Total forfeitures at December 31, 2004 and 2003 were $58,319 and $91,814, respectively. The $91,814 in forfeitures was used to reduce the Company's matching contributions during the year ended December 31, 2004. NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES BASIS OF ACCOUNTING - The financial statements of the Plan are prepared under the accrual basis of accounting. Administrative and other expenses are recorded as incurred. Benefits are reported when paid. BASIS OF PRESENTATION - The financial statements have been prepared in compliance with the Department of Labor Rules and Regulations for reporting and disclosure under ERISA. USE OF ESTIMATES - The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of net assets available for benefits at the date of the financial statements and the reported amounts of additions to net assets and deductions from net assets during the reporting period. Actual results could differ from those estimates. 5 ONYX ACCEPTANCE CORPORATION 401(K) SAVINGS PLAN NOTES TO FINANCIAL STATEMENTS (CONTINUED) DECEMBER 31, 2004 AND 2003 NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) VALUATION OF INVESTMENTS - Investments are included in the accompanying financial statements at fair value as determined by quoted market prices. Interest is recorded on the accrual basis and is included in the investment's value. Purchases and sales of securities are recorded on a trade date basis. Dividends are on the ex-dividend date. RISKS AND UNCERTAINTIES - The Plan provides for various investment options in any combination of investment securities. Investment securities are exposed to various risks, such as interest rate, market, and credit. Due to the level of risk associated with certain investment securities and the level of uncertainty related to changes in the value of investment securities, it is at least reasonably possible that changes in risks in the near term would materially affect participant's account balances and the amounts reported in the Statements of Net Assets Available for Plan Benefits and the Statements of Changes in Net Assets Available for Plan Benefits. NOTE 3 - INVESTMENTS Investment accounts greater than 5 percent of the Plan's net assets as of December 31, 2004 and 2003, respectively, are summarized as follows: 2004 2003 ----------- ----------- Alliance Technology Fund .................... $ 1,077,215 $ 925,527 Alliance Premier Growth Fund ................ 1,037,331 804,703 Alliance Growth Fund ........................ 757,192 607,995 Alliance Growth & Income Fund ............... 920,562 773,021 AFD Exchange Reserves Fund .................. 442,835 424,742 Onyx Acceptance Corp.

At December 31, 2004 and 2003, investments in Onyx Acceptance Corporation common stock comprised 54 percent and 36 percent, respectively, of total net assets available for benefits. NOTE 6 - PARTY-IN-INTEREST Certain Plan investments are managed by TruSource, the trustee as defined by the Plan and, therefore, these transactions qualify as party-in-interest transactions. Fees paid by the Plan for the investment management services amounted to $14,915 and $19,240 for the years ended December 31, 2004 and 2003, respectively. NOTE 7 - PLAN TERMINATION Although the Company has not expressed any intent to do so, it has the right under the Plan to discontinue its contributions at any time and to terminate the Plan subject to the provisions of ERISA. In the event of Plan termination, the net assets of the Plan will be allocated as prescribed by ERISA and its related regulations, so that each participant receives 100 percent of his or her account balance as of the date of the termination. NOTE 8 - TAX STATUS The Internal Revenue Service ("IRS") has determined and informed the Company by letter dated January 18, 2005 that the Plan and related trust are designed in accordance with applicable sections of the IRC. The Company and plan administrator believe the Plan is currently designed and being operated in compliance with the applicable requirements of the IRC. Therefore, the Plan is expected to continue as exempt from federal income taxes.
