Item 12.  Results of Operations and Financial Condition


                    GMAC FIRST QUARTER 2004 EARNINGS SUMMARY

General Motors Acceptance Corporation (GMAC) recorded its highest first quarter
earnings ever in the first quarter of 2004. Consolidated net income of $786
million was up $87 million from the $699 million earned in the same quarter of
2003.

For the quarter, net income from financing operations totaled $442 million, up
$140 million from the $302 million earned in the prior year. The increase
reflects lower credit loss provisions and improved off-lease remarketing
results, which more than offset the unfavorable impact of lower net interest
margins.

GMAC Insurance Holdings, Inc. generated net income of $91 million in the first
quarter of 2004. Earnings were up $65 million from the same period in 2003, due
to improved investment portfolio performance and continued growth in
underwriting income.

GMAC Mortgage Group, Inc. generated earnings of $253 million, down $118 million
from the prior year first quarter record. These decreased earnings resulted from
lower mortgage origination volume, reduced mortgage refinancing activity, and
decreased pricing margins.
