REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM The Administrator Consumer Portfolio Services, Inc. 401(k) Plan: We have audited the accompanying statements of net assets available for benefits of the Consumer Portfolio Services, Inc. 401(k) Plan (the "Plan") as of December 31, 2005 and 2004, and the related statements of changes in net assets available for benefits for the years then ended. 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 the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. The Plan 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 on the effectiveness of the Plan's internal control over financial reporting. Accordingly, we express no such opinion. 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 benefits of the Plan as of December 31, 2005 and 2004, and the changes in net assets available for benefits for the years then ended in conformity with U.S. generally accepted accounting principles. Our audit was performed for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental schedule, schedule H, line 4i - schedule of assets (held at end of year) 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. The 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 and, in our opinion, is fairly stated, in all material respects, in relation to the basic financial statements taken as a whole.

CONSUMER PORTFOLIO SERVICES, INC. 401(K) PLAN Notes to Financial Statements December 31, 2005 and 2004 (1) DESCRIPTION OF THE PLAN The following description of the Consumer Portfolio Services, Inc. (the Plan Sponsor or CPS) 401(k) Plan (The Plan) provides only general information. Participants should refer to the Plan agreement for a more complete description of the Plan's provisions. (a) GENERAL The Plan was established as a profit sharing plan with a cash or deferred arrangement on January 1, 1994. The Plan was restated as of January 1, 1996 to permit investment in the Plan Sponsor's common stock without regard to Section 407(a) of ERISA. Effective January 1, 2003 the Plan Sponsor adopted the Mass Mutual Life Insurance Company Flexinvest(R) Prototype Non-Standardized 401(k) Profit Sharing Plan. The Plan is a defined contribution plan which provides retirement benefits for eligible employees of the Plan Sponsor. It is subject to the provisions of the Employee Retirement Income Security Act of 1974 (ERISA). (b) ADMINISTRATION OF THE PLAN The Plan is administered by the Human Resources Department (the Plan Administrator) of the Plan Sponsor. The Plan Administrator consults with the board of directors and other key management of the Plan Sponsor when managing the operations and the administration of the Plan. The Plan is operated under an agreement which requires that Mass Mutual Retirement Savings (Mass Mutual), custodian and recordkeeper, holds and distributes the funds of the Plan in accordance with the text of the Plan and the instructions of the Plan Administrator or its designees. (c) CONTRIBUTIONS Employees are eligible to participate in the Plan after completing 90 days of service. In accordance with the Plan, participants may contribute up to 50% of their annual compensation. Contributions are subject to certain limitations as defined in the Plan as well as a maximum of $14,000 and $13,000 for the years ended December 31, 2005 and 2004, respectively, under the Internal Revenue Code of 1986 (exclusive of additional contributions that are permitted if certain age criteria are satisfied). Participants may roll over into the Plan amounts representing distributions from other qualified plans. The Plan Sponsor may make a discretionary matching contribution equal to a discretionary percentage of the participant's pretax contributions. Discretionary matching contributions were $427,378 and $399,961 for the years ended December 31, 2005 and 2004, respectively. (d) PARTICIPANT ACCOUNTS Each participant's account is credited with the participant's contributions, allocations of the Plan Sponsor's matching contributions and investment earnings and charged with an allocation of expenses and investment losses. Allocations are based on participant earnings or account balances, as defined. 5

CONSUMER PORTFOLIO SERVICES, INC. 401(k) PLAN Notes to Financial Statements (Continued) December 31, 2005 and 2004 (1) DESCRIPTION OF THE PLAN (CONTINUED) (e) VESTING Participants are immediately vested in their contributions plus actual earnings thereon. Vesting in the Plan Sponsor's matching contributions plus actual earnings thereon is based on years of continuous service. A participant vests at the rate of 20% after two years of credited service and 20% each year thereafter until 100% is reached after six years of credited service. Participants are also fully vested at death, retirement, and upon termination for disability. (f) INVESTMENT OPTIONS The Plan offers various investment options which are managed by several outside investment managers. Upon enrollment in the Plan, participants may direct their contributions in any of the investment options offered at the time. Participants may change their investment options daily. Participants should refer to the Plan fund description pamphlet for a complete description of the investment options and for the detailed composition of each investment fund. (g) PARTICIPANTS LOANS Participants may borrow from their accounts. Loan transactions are treated as a transfer to (from) the investment funds. The loans are secured by the balance in the participant's account and bear interest at a rate commensurate with local prevailing rates as determined by the Plan Administrator. Loans are limited to the lesser of $50,000, reduced by the highest outstanding loan balance during the preceding 12 months, or 50% of the participant's vested account balance. A loan shall be repaid within five years, unless it is used for the purchase of a primary residence. Principal and interest are paid ratably through payroll deductions. Participant loans are included in the statements of net assets available for plan benefits at their outstanding balances, which approximate fair value of the notes. The notes are payable through payroll deductions in installments of principal plus interest at rates between 5.00% and 11.50%, with final payments due between February 2005 and June 2018, and are secured by the participants' vested account balances. (h) PAYMENTS OF BENEFITS Upon termination of service, a participant may elect to receive either a single lump sum payment in cash equal to the value of the vested interest in his or her account, or a series of substantially equal annual or more frequent installments over a period not to exceed the participant's life expectancy. Benefits are recorded when paid. 6

CONSUMER PORTFOLIO SERVICES, INC. 401(k) PLAN Notes to Financial Statements (Continued) December 31, 2005 and 2004 (1) DESCRIPTION OF THE PLAN (CONTINUED) (i) FORFEITED ACCOUNTS Through December 31, 2002, forfeitures were applied to reduce any employer contribution. Effective January 1, 2003, forfeitures attributable to matching contributions will be applied first to reduce expenses related to the administration of the Plan and then to reduce any employer contributions. As of December 31, 2005 and 2004, forfeited accounts totaled $332,718 and $245,420, respectively. (j) PLAN TERMINATION Although it has not expressed any intent to do so, the Plan Sponsor has the right under the Plan to discontinue contributions at any time and to terminate the Plan subject to the provisions of ERISA. In the event of Plan termination, participants will become 100% vested in their accounts. (k) PLAN MERGER Effective January 1, 2004 the board of directors approved a merger of The Finance Company 401(k) Plan into the Plan. The sponsor of The Finance Company 401(k) Plan was The Finance Company, a subsidiary of Consumer Portfolio Services, Inc. Assets of $2,061,590 were transferred into the Plan on March 2, 2004. (2) SIGNIFICANT ACCOUNTING POLICIES (a) BASIS OF ACCOUNTING The financial statements of the Plan have been prepared on the accrual basis of accounting. (b) INVESTMENTS Publicly traded securities are carried at fair value based on published market quotations. Shares of mutual funds are valued at the net asset value of shares held by the Plan at year-end. Participant loans are valued at their outstanding balances, which approximates fair value. Purchases and sales of investments are recorded on a trade-date basis. Dividends are recorded on the ex-dividend date. Interest income is recorded on the accrual basis. Realized gains and losses on investments are based on the market value of the asset at the beginning of the year or at the time of purchase for assets purchased during the year and the related fair value on the day the investments are sold during the year. (c) ADMINISTRATIVE EXPENSES The Plan and the Plan Sponsor share in plan expenses. Certain direct investment expenses, such as loan, withdrawal or distribution processing fees are deducted from participants' accounts. 7

CONSUMER PORTFOLIO SERVICES, INC. 401(k) PLAN Notes to Financial Statements (Continued) December 31, 2005 and 2004 (2) SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) (d) USE OF ESTIMATES The Plan Administrator has made estimates and assumptions relating to the reporting of assets and liabilities to prepare these financial statements in conformity with accounting principles generally accepted in the United States of America. Accordingly, actual results may differ from those estimates. (e) RISKS AND UNCERTAINTIES The Plan provides for various investments options in money market funds, mutual funds, guaranteed interest accounts and the common stock of Consumer Portfolio Services, Inc. Investment securities are exposed to various risks such as interest rate, market, and credit risks. Due to the level of uncertainty related to changes in value of investment securities, it is at least reasonably possible that changes in the various risk factors could materially affect participants' account balances and the amounts reported in the financial statements. (f) CONCENTRATION Investments in the common stock of Consumer Portfolio Services, Inc. comprise approximately 17% and 15% of the Plan's investments as of December 31, 2005 and 2004, respectively. (g) RECLASSIFICATIONS Certain balances in the 2004 financial statements have been reclassified to conform to the current year presentation. This reclassification had no effect on net assets or the change in net assets. 8

The Plan has been amended since receiving the determination letter. However, the Plan Administrator believes that the Plan is designed and is currently being operated in compliance with the applicable requirements of the IRC. Accordingly, no provision for income taxes is included in the accompanying financial statements. 9
