Report of Independent Registered Public Accounting Firm

Pension Committee
Cooper-Standard Automotive
(Gaylord, Michigan Plant) UAW Local 388
Collectively Bargained Savings and Retirement Plan

We have audited the accompanying statements of assets available for benefits of Cooper-Standard Automotive (Gaylord, Michigan Plant) UAW Local 388 Collectively Bargained Savings and Retirement Plan as of December 31, 2003 and 2002 and the related statement of changes in assets available for benefits for the year ended December 31, 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 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. 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 assets available for benefits of the Plan at December 31, 2003 and 2002, and the changes in its assets available for benefits for the year ended December 31, 2003, in conformity with U.S. generally accepted accounting principles.

Our audits were performed for the purpose of forming an opinion on the financial statements taken as a whole. The accompanying supplemental schedule of assets (held at end of year) as of December 31, 2003, is presented for purpose of additional analysis and is not a required part of the 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 our audits of the financial statements and, in our opinion, is fairly stated in all material respects in relation to the financial statements taken as a whole.

1. Description of Plan

The following description of Cooper-Standard Automotive (Gaylord, Michigan Plant) UAW Local 388 Company Collectively Bargained Savings and Retirement Plan (the Plan) provides only general information. 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 all employees who have completed the 90 day probationary period and are covered by the collective bargaining agreement between UAW Local 388 and Cooper-Standard Automotive (the Company and Plan Administrator). The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974 (ERISA).

Contributions

Each year, participants may contribute up to 10% of their pretax compensation. Participants may direct their contributions to any of the Plan’s investment fund options.

The Company contributions are made annually as provided in the Plan document and at the discretion of the Company’s Board of Directors. All Company matching contributions were invested in the Cooper Tire and Rubber Company common stock until they become vested, after which they are invested as directed by the participant.

Participant Accounts

Individual accounts are maintained for each participant in the Plan. Each participant’s account is credited with the participant’s contributions, allocation of the Company’s contributions, and Plan earnings. The benefit to which a participant is entitled is the benefit that can be provided from the participant’s account.

Vesting

The participants are immediately vested in their contributions and the Company’s contributions plus actual earnings thereon.

1. Description of Plan (continued)

Participant Loans

Participants may borrow the lesser of 100 percent of their participant elected contributions account or 50% of the vested value of their entire account. In no event should the maximum loan exceed $50,000. The interest rate is established based on the prime rate. Interest rates as of December 31, 2003 range from 4.0% to 4.25%. The loan repayment schedule can be no longer than 54 months. Principal and interest is paid ratably through payroll deductions.

Participant Withdrawals

In the event of retirement, death, termination, permanent disability or other separation from service, participants shall be entitled to receive an amount equal to the value of the vested interest in their account. Payment of benefits may be taken in a lump sum cash distribution or nearly equal quarterly installments over a specified period.

In the event of hardship, as defined, participants may make a partial or full distribution of their accounts, subject to certain tax withholdings.

Termination of the Plan

Although it has not expressed any intent to do so, the Company has the right, under the Plan, to terminate the Plan subject to the provisions of ERISA. In the event of Plan termination, participants will become 100% vested in their accounts.

2. Summary of Accounting Policies

2. Summary of Accounting Policies (continued)

Investment Valuation and Income Recognition

Except for the investments contracts held in the Investment Trust, the Plan’s investments are stated at fair value, which equals the quoted market price on the last business day of the Plan year. The shares of mutual funds are valued at quoted market prices, which represent the net asset value of shares held by the Plan at year-end. The participant loans are valued at their outstanding balances, which approximate fair value.

Investment contracts are recorded at their contract values, which represent contributions and reinvested income, less any withdrawal plus accrued interest, because these investments have fully-benefit responsive features. There are no reserves against contract values for credit risk of contract issues or otherwise. The average yield was approximately 4.2% in 2003. The crediting interest rate of these investment contracts is reset monthly by the issuer but cannot be less than zero and ranged from 1.4% to 6.6% at December 31, 2003.

Purchases and sales of securities are recorded on a trade-date basis. Interest income is recognized when earned. Dividends are recorded on the ex-dividend date.

Administrative Expenses

The Company pays the administrative expenses of the Plan, unless the expenses relate to specific investment directions of the participant.

Use of Estimates

The preparation of financial statements in conformity with U.S. generally accepted accounting principles require management to make estimates that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.

4. Investment Trust

Certain investments of the Plan are held in an Investment Trust, which also combines similar investments of the other defined contribution plans sponsored by Cooper Tire & Rubber Company. Each participating retirement plan has an undivided interest in the Investment Trust. The Plan’s interest in the Investment Trust was determined by the Plan’s relative asset value to the Investment Trust’s total asset value at the end of the year. Investment income is allocated to the Plan based on its pro-rata share in the net assets of the Investment Trust.

5. Nonparticipant-Directed Investments

The Cooper Tire & Rubber Company common stock held in the Investment Trust is a nonparticipant-directed investment. Information about the significant components of changes in net assets related to the nonparticipant-directed investment is as follows for the year ended December 31, 2003:

6. Income Tax Status

The Plan has received a determination letter from the Internal Revenue Service dated January 6, 2004, stating that the Plan is qualified under Section 401(a) of the Internal Revenue Code (the Code) and, therefore, the related trust is exempt from taxation. Subsequent to this issuance of the determination letter, the Plan was amended. Once qualified, the Plan is required to operate in conformity with the Code to maintain its qualification. The Plan Administrator has indicated that it will take the necessary steps, if any, to bring the Plan’s operations into compliance with the Code.

7. Related-Party Transactions

Certain Plan investments are shares of mutual funds managed by the Trustee, and, therefore, these transactions qualify as party-in-interest transactions. There have been no known prohibited transactions with a party-in-interest.

8. Risks and Uncertainties

The Plan invests in various 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, it is at least reasonably possible that the changes in the values of investment securities will occur in a near term and that such changes could materially affect participants’ account balances and the amounts reported in the statements of assets available for benefits.
