                           The Commerce Group, Inc.
                   Announces 2004 Second Quarter Results
                           and Comparison to 2003

WEBSTER, Mass., July 23, 2004 -- The Commerce Group, Inc. (NYSE:CGI)
today reported 2004 second quarter results.  Net earnings were $37.4
million, or $1.14 per diluted share, compared to net earnings of $71.5
million or $2.22 per diluted share for 2003.

During the second quarter of 2004, the Company had net realized
investment losses of $8.6 million or $0.17 per diluted share, compared
to gains of $65.9 million or $1.53 per diluted share in the second
quarter of 2003.  A complete breakdown of this information is included
in the attached tables.

Earned premiums were $404.5 million for the second quarter of 2004,
compared to $350.3 million for 2003.  A schedule of direct written
premiums to earned premiums is included in the attached tables.

The second quarter GAAP consolidated operating combined ratio was
91.7%, compared to 100.5% for 2003.  The decrease in the combined
ratio was the result of a decrease in both the loss ratio and the
underwriting ratio.  The Companys GAAP consolidated loss ratio for the
second quarter of 2004 decreased to 68.4% from 76.9% during the same
period last year.  The improvement was primarily the result of an
increase in average earned premium revenue per automobile and a
decline in the current year personal automobile physical damage claim
frequency. The Companys GAAP consolidated underwriting ratio decreased
to 23.3%, as compared to 23.6% for last years second quarter,
primarily as a net result of lower 2004 policy year mandated
Massachusetts personal automobile commission rates partially offset by
higher accrued contingent commissions.

Cumulative June 30, 2004 Results

Net earnings for the first six months of 2004 were $88.4 million, or
$2.70 per diluted share, compared to net earnings of $84.4 million or
$2.62 per diluted share for 2003.

During the first six months of 2004, the Company had net realized
investment gains of $11.9
million or $0.24 per diluted share, compared to gains of $60.0 million
or $1.33 per diluted share in the same period of 2003.  A complete
breakdown of this information is included in the attached tables.

Earned premiums were $800.1 million for the six months of 2004,
compared to $688.3 million for 2003.  A schedule of direct written
premiums to earned premiums is included in the attached tables.

CGI 2Q04 Earnings Release (page 2 of 7)

The 2004 six month GAAP consolidated operating combined ratio was
92.7%, compared to 100.5% for 2003.  The decrease in the combined
ratio was the result of a decrease in the loss ratio, partially offset
by an increase in the underwriting ratio.  The Companys GAAP
consolidated loss ratio for the first six months of 2004 decreased to
69.8% from 79.0% during the same period last year.  The improvement
was the result of several factors, including: (1) an increase in
average earned premium revenue per automobile; (2) a decline in the
current year personal automobile physical damage claim frequency; and,
(3) a decrease in the overall Commonwealth Automobile Reinsures
(C.A.R.) deficit. The Companys GAAP consolidated underwriting ratio
increased to 22.9% for the first six months of 2004, as compared to
21.5% for 2003, primarily as a net result of higher accrued contingent
commissions offset by lower 2004 policy year mandated Massachusetts
personal automobile commission rates.

A complete presentation of June 30, 2004 and 2003 financial statement
information, including a breakdown of the components of the combined
ratio and realized investment gains and losses, is included in the
financial statements attached to this press release.

Additional supplemental financial information will be available on
July 26th on the Companys website at www.commerceinsurance.com, under
the "Links" section of the "News and Investor Information" area.

At June 30, 2004, the Company had authority to purchase approximately
858,000 additional shares of common stock under the current Board of
Directors stock re-purchase authorization, which excludes treasury
stock acquired as a result of officer stock option exercises.  During
the second quarter of 2004, the Company acquired 493,361 shares of
treasury stock at an average price of $45.95 per share as a result of
option exercises. Also during the second quarter, the Company issued
approximately 924,000 shares of common stock related to all option

     (1)     GAAP consolidated operating ratios are calculated as in (2) below using the combined
             insurance subsidiaries loss and underwriting results, adding to them the expenses of the
             holding companies (corporate expenses) in order to equal the loss and underwriting
             expense amounts on the income statement.  For purposes of the U/W ratio, underwriting
             expenses are grossed-up for the increase in deferred acquisition costs of $5,766 and $4,693
             for the three months ended and $20,769 and $19,005 for the six months ended June 30, 2004
             and 2003, respectively.

    (2)      GAAP operating ratios for combined insurance subsidiaries are calculated as follows:
              (a)  The loss ratio represents losses and LAE divided by earned premiums; and,
              (b)  The underwriting ratio represents underwriting expenses (excluding changes in deferred acquisition
                   costs), divided by net premiums written.  No corporate expenses are included in the calculations.
