REPORT OF INDEPENDENT AUDITORS


The Benefits Committee
The Commerce Group, Inc.

We have audited the accompanying statements of net assets available for
benefits of The Commerce Group, Inc. 401(k) Plan (the Plan) as of
December 31, 2000 and 1999, and the related statements of changes in net
assets available for benefits for the years then ended and for the
period from September 1, 1998 (date of inception) through December 31,
1998.  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, the net assets available for benefits
of the Plan at December 31, 2000 and 1999, and the changes in its net
assets available for benefits for the years then ended and for the
period from September 1, 1998 (date of inception) through December 31,
1998, in conformity with accounting principles generally accepted in the
United States.

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 for investment purposes as of December 31, 2000
is presented for purposes 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.  This supplemental schedule is the responsibility of the
Plan's management.  The supplemental schedule has been subjected to
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.

THE COMMERCE GROUP, INC. 401 (k) PLAN
NOTES TO FINANCIAL STATEMENTS
December 31, 2000
NOTE A - Description of Plan

1.   General

The Commerce Group, Inc. 401(k) Plan (the "Plan") was adopted by
The Commerce Group, Inc. (the "Company") effective September 1,
1998.  It is subject to many of the reporting and disclosure,
minimum coverage, vesting, fiduciary responsibility and civil
enforcement provisions of the Employee Retirement Income Security
Act of 1974.  The Plan is a voluntary retirement savings account
which allows each participant to direct the investment of their
account balances among options which include money market funds,
self directed brokerage and mutual funds, one of which consists
entirely of the common stock of the Company.  No matching
contributions are made by the Company to the Plan.  The Plan may be
amended and/or terminated by the Company at any time; however, no
such event may adversely affect the rights of Participants in the
Plan with respect to contributions made prior to the date of such
event.  All administrative expenses of the Plan are paid for by the
Company.

On August 18, 2000, the Board of Directors of the Company (the
"Board") voted to replace Merrill Lynch Trust Co., FSB ("Merrill
Lynch") with Fidelity Management Trust Company ("Fidelity") as the
Trustee of the Plan, effective January 1, 2001.  The Board also
amended the Plan by adopting the Fidelity Corporate Plan for
Retirement also effective as of January 1, 2001.  A blackout
period, for the Month of December, 2000, was imposed on the Plan in
order to facilitate the transfer.  During this period, participants
could not make any investment changes or additional contributions
to Merrill Lynch.  On November 16, 2000, the Plan Investment
Committee approved moving investments held in the form of the
Company's stock over to The Commerce Group, Inc. Employee Stock
Ownership Plan ("ESOP") in the form of a KSOP amendment.  The KSOP,
which will be a component of the ESOP, will allow employees to
participate in the purchase of Company stock on a pre-tax basis for
their retirement.  Fidelity prohibits company stock purchases in a
401(k) plan administered by them.  Funds, other than Company stock,
were cashed out and transferred to Fidelity effective January 1,
2001.  As a result of the fact that Company stock will no longer be
purchased as part of the Plan, the Company will no longer be
required to file Form 11-K in the future.

2.  Investment Options Available to Plan Participants

The Company has a Trust Agreement with Merrill Lynch as Trustee,
providing for the management, investment and reinvestment of Plan
assets.  The investment options available to Plan Participants are
as follows:
a.   Commerce Group, Inc. Common Stock Fund - The fund invests
in the common stock of the Company.
b.   Merrill Lynch Retirement Preservation Trust - Seeks to
provide preservation of capital, liquidity and current income
levels that are  typically higher than those by money market funds.
c.   Merrill Lynch Corporate Bond Fund - Seeks a high level of
current income and as a secondary objective, the fund seeks capital
appreciation.
d.   Merrill Lynch Capital Fund - Seeks the highest total
investment return consistent with prudent risk through a fully
managed investment policy in equity, fixed income and convertible
securities.
e.   Merrill Lynch Basic Value Fund - Seeks capital appreciation
and secondary income by investing primarily in large cap equities
that appear to be undervalued.
f.    Merrill Lynch Global Allocation Fund - Seeks high total
investment return utilizing U.S. and foreign equity, fixed income
and money market securities.  The investment approach provides the
fund with the opportunity to benefit from anticipated shifts in the
relative performance of different types of securities and different
markets.
g.   Merrill Lynch Self-Direct Brokerage - Enables the
participant to purchase and hold investments that are not offered
as part of the Plan's core investment options.
h.   Merrill Lynch S&P 500 Index Fund - The fund is a passive
mutual fund which invests in the largest 500 U.S. publicly traded
companies.
i.    MFS Massachusetts Investors Growth Stock Fund - Seeks
long-term growth of capital through companies believed to have
better than average long-term growth potential.  Emphasis is placed
on high-quality companies with characteristics such as:  strong
management, history of consistent long-term earnings growth and
market leadership.
j.    GAM International Fund - Seeks long-term capital
appreciation primarily in equity securities in foreign countries,
focusing on Canada, the United Kingdom, continental Europe and the
Pacific Basin.
k.   Lord Abbett Developing Growth Fund - Seeks to provide long-
term capital appreciation by primarily investing in the stocks of
small companies with above average long-term rates, strong
management, undervalued assets and companies with exciting
prospects.

THE COMMERCE GROUP, INC. 401 (k) PLAN
NOTES TO FINANCIAL STATEMENTS (continued)
December 31, 2000

NOTE A - Description of Plan (continued)

3.  Eligibility

Employees of the Company become eligible  to participate in the
Plan  after (1)  three months of  service with the Company, and,
(2) upon attaining 18 years of age (changed from 21 years of age
effective December 31, 1998).  Employees cease to be eligible to
participate in the Plan upon termination of their employment with
the Company.

4.  Contributions

Eligible employees may contribute a portion of their pay to the
Plan on a tax deferred basis, so that the eligible employee is not
taxed on the money they contribute until funds are distributed.
Eligible employees are allowed to contribute from 1% up to a
maximum of 15% of their covered compensation, subject to annual
maximum limits imposed by the Internal Revenue Service.  Eligible
employees may also contribute up to 100% of their pretax cash bonus
which they may be eligible to receive twice yearly or the same
percentage as is applied to their regular pay, also subject to a
maximum dollar amount on all contributions allowable by the
Internal Revenue Code.  Eligible employees may also make rollover
contributions under the Plan from another qualified plan or an
individual retirement account.  The Company does not match employee
contributions.

5.  Vesting

Because participants' account balances consist solely of amounts
they have deferred from their own compensation (and the investment
income derived therefrom) participating employees are 100% vested
in their accounts at all times.

6.  Distributions

Participating employees may withdraw funds from the Plan prior
to retirement only in the circumstance of a demonstrated financial
hardship.  Upon termination of employment for reasons other than
death, disability or retirement, former participants may also
request an eligible rollover distribution.

7.  Federal Income Tax Status

The Plan has received a determination letter from the Internal
Revenue Service dated August 4, 1999, 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.
Once qualified, the Plan is required to operate in conformity with
the Code to maintain its qualification.  The Plan Administrator
believes the Plan is being operated in compliance with the
applicable requirements of the Code and, therefore, believes that
the Plan is qualified and the related trust is tax exempt.

8.  Risks and Uncertainties

The Plan provides for various investment options in registered
investment companies.  Investment securities are exposed to various
risks, such as interest rate, market and credit risks.  Due to the
level of risks associated with investment securities, it is

THE COMMERCE GROUP, INC. 401 (k) PLAN
NOTES TO FINANCIAL STATEMENTS (continued)
December 31, 2000

Note B - Significant Accounting Policies

1.  Basis of Accounting

The financial statements of the Plan have been prepared on the
accrual basis.  All expenses associated with the administration of
the Plan, with the exception of the charge for partial or total
distribution from a participating employee's account, are paid
directly by the Company and accordingly, are not reflected in the
accompanying statements.

2.  Valuation of Investments

The Plan's investments, including the common stock of the
Company, are stated at fair value, based on quoted market prices.
The shares of the registered investment companies are valued at
quoted market prices, which represent the net asset values of the
shares held by the Plan at December 31, 1999 and 2000.  The Merrill
Lynch Retirement Preservation Trust is valued at cost, which
approximates fair value.

3.  Use of Estimates

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

Note C - Investments

Accumulated unrealized gains at December 31, 2000 and 1999 and
the net increase (decrease) in unrealized gains in 1999 and 2000
