Car parts maker Magna International has reached an agreement in principle to rescue GM Europe, owner of Opel and Vauxhall, reports say.
The agreement was reached with General Motors, but is subject to the approval of the German government, which will be providing funding to the new owner.
Fiat, who were also interested, said it would not be attending Friday's talks with the German government.
General Motors USA is expected to declare Chapter 11 bankruptcy on Monday.
There is due to be a meeting in Berlin at 1800 local time, which will be attended by Chancellor Angela Merkel, the ministers involved and officials from the German states that contain GM plants to discuss whether to approve the deal. Magna and General Motors will not be attending the meeting at first, although they may be invited later.
There have been suggestions in the German media that it may be cheaper for the German government to allow GM Europe to declare itself insolvent than to allow it to be bought.
Magna and GM will have to make sure that GM Europe is restructured in a way that will protect the carmaker if, as expected, its parent company in the US declares itself bankrupt.
