ITEM 8.01.  OTHER EVENTS

General Motor's Investment in Fiat Auto Holdings (FAH)

   On December 14, 2004, senior executives of General Motors Corporation (GM)
and Fiat S.p.A. met to discuss a broad range of issues relating to their
alliance as well as issues relating to their dispute concerning whether the
recapitalization of FAH in 2003, and the 2003 sale by Fiat Auto of a majority
of FIDIS, constituted material breaches of the Master Agreement. They also
discussed the standstill agreement that expired on December 14, 2004 relating
to the disputes. (For further information see the Management Discussion and
Analysis portion of GM's last Form 10-Q under the heading "Investment in Fiat
Auto Holdings.")

The standstill was not renewed or extended. At the meeting GM informed Fiat that
it intended to immediately initiate formal mediation of the disputes as provided
for in Section 10.08 of the Master Agreement. The mediation process, which GM
initiated today, is designed to facilitate resolution of disputes through
dialogue between the two CEOs before either party resorts to other remedies,
including litigation.

During the mediation process the two companies expect to discuss broad issues
relating to their alliance as well as seeking to resolve the disputes. No
assurances can be given that mediation will succeed in resolving these disputes.
