                         Report of Independent Auditors


Employee Benefits Committee
Comerica Incorporated Preferred Savings Plan

We have audited the accompanying statements of assets available for benefits of
the Comerica Incorporated Preferred Savings Plan (the "Plan") as of December 30,
2002 and 2001 and the related statement of changes in assets available for
benefits for the year ended December 30, 2002. 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 auditing standards generally accepted
in the 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, information regarding the Plan's assets available for
benefits at December 30, 2002 and 2001 and the changes therein for the year
ended December 30, 2002, in conformity with accounting principles generally
accepted in the United States.

Our audits were made for the purpose of forming an opinion on the financial
statements taken as a whole. The accompanying supplemental schedules of assets
(held at end of year) as of December 30, 2002 and reportable transactions for
the year then ended, are presented for purposes of additional analysis and are
not a required part of the financial statements but are 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. These supplemental schedules are the responsibility of the Plan's
management. The supplemental schedules have been subjected to the auditing
procedures applied in our audits of the financial statements and, in our
opinion, are fairly stated in all material respects in relation to the financial
statements taken as a whole.

                          Year Ended December 30, 2002



1.   DESCRIPTION OF THE PLAN

The Comerica Incorporated Preferred Savings Plan (the "Plan") is a defined
contribution plan covering all eligible employees of Comerica Incorporated (the
"Corporation") and certain subsidiaries.

On January 29, 2001, the Corporation acquired Imperial Bancorp. As a result, the
assets from the Employee Stock Ownership Plan of Imperial Bancorp and the Salary
Investment Plan of Imperial Bancorp transferred to the Plan on August 31, 2001
and September 17, 2001, respectively. Participants in the Imperial Bancorp Plans
became eligible to contribute to the Plan as of July 1, 2001.

Information about the Plan agreement, participants' investment alternatives and
the vesting and benefit provisions is contained in the pamphlet "Comerica
Incorporated Preferred Savings Plan." Copies of this pamphlet are available from
the Corporation's Human Resources Office.

Participants may make annual contributions to the Plan on a pre-tax basis, not
to exceed the lesser of 50% and 20% in 2002 and 2001, respectively, of the
participant's annual compensation or the IRS allowed maximum ($11,000, plus an
additional $1,000 for participants over 50 years of age, in 2002 and $10,500 in
2001).

The Corporation will match a percentage of the first $3,000 of the participant's
pre-tax contributions, as defined by the Plan. In addition, the Corporation may
make discretionary contributions based upon attaining certain corporate
financial performance measurements. Both the Corporation match and discretionary
contribution are invested in the Corporation's common stock.

During 1999, the Plan was amended to add an Employee Stock Ownership Plan
("ESOP") provision to the Plan. Participants' investments in the Corporation's
common stock, including vested corporate matching contributions, are held in an
ESOP account and dividends earned on the stock are paid outside the Plan.
Participants may elect to either reinvest the dividends in the Corporation's
common stock within the Plan or receive the dividends as cash with their regular
pay.

Contributions receivable represent amounts due from the Corporation under a
performance match program, which rewards employees through a corporate
contribution to the participants' accounts.


                                                                               4

                  Comerica Incorporated Preferred Savings Plan

                    Notes to Financial Statements (continued)

                         December 30, 2002 and 2001 and
                          Year Ended December 30, 2002



1.   DESCRIPTION OF THE PLAN (CONTINUED)

Participants direct the investment of their accounts, except the nonparticipant
directed investment in the Corporation's common stock, among the investment
funds offered by the Plan. The benefit to which a participant is entitled is the
benefit that can be provided from the participant's account.

Prior to the 2002 plan year, all employer matches and employer contributions
were made in Comerica Incorporated common stock and permanently held in a
restricted Comerica Incorporated common stock account. At the beginning of plan
year 2002, the Plan was changed to provide that these employer matches and
employer contributions are to be held in a restricted Comerica Incorporated
common stock account until the end of the calendar year, when the assets held in
such account become vested and unrestricted and, therefore, eligible to be
reallocated to other fund options. Approximately $73.3 million of restricted
common stock was transferred to unrestricted funds during the plan year ended
December 30, 2002.

The Corporation has the right to amend or terminate the Plan at any time. In the
event the Plan is terminated, all participants' accounts become fully vested and
nonforfeitable.

2.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The fair values of the participation units owned by the Plan in mutual and
collective trust funds are based on the net asset values on the last business
day of the plan year.

Marketable securities are stated at fair value. Securities traded on a national
securities exchange are valued at the last reported sales price on the last
business day of the plan year. Investments traded in the over-the-counter market
and listed securities for which no sale was reported on that date are valued at
the average of the last reported bid and ask prices.

The fair value of investments in the Corporation's common stock is based on the
last reported sales price on the last business day of the plan year as traded on
the New York Stock Exchange.

The participant loans are valued at their outstanding balances, which
approximate fair value.

Administrative expenses incurred in connection with the operation of the Plan
are borne by the Corporation, except for a $10 per quarter loan fee paid by
participants.


                                                                               5

                          Year Ended December 30, 2002



2.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

The preparation of financial statements in conformity with accounting principles
generally accepted in the United States requires management to make estimates
and assumptions that affect the amounts in the financial statements and
accompanying notes. Actual results could differ from those estimates.

3.   INVESTMENTS

The fair value of individual investments that represent 5% or more of the Plan
assets at the end of the respective years are as follows:

                          Year Ended December 30, 2002



6.   TAX STATUS

The Plan has received determination letters from the Internal Revenue Service
dated June 29, 1998 and December 1, 1998, 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 the issuance of these
determination letters, new provisions in the Code were made and the Plan was
amended accordingly. The Plan has applied for but has not received a new
determination letter from the Internal Revenue Service stating the Plan is
qualified under the provisions of the Code. However, the plan administrator
believes the Plan is being operated in compliance with the applicable
requirements of the Code and, therefore, believes that the Plan, as amended, is
qualified and the related trust is tax exempt.

7.   DIFFERENCES BETWEEN FINANCIAL STATEMENTS AND FORM 5500
