I wouldn't worry about it. GM will not go bust. They may reduce in size and sell off certain divisions but thats about it.
Think about it Ford are not better off, Damiler Crysler have major issues. Nissan is totally broke and has been for years. Ford has or had a major stake in Mazda, Mitshibushi have major issues, MG Rover have gone bust. Fiat (who own Ferrari and Maserati) are in major trouble, Lancia only bearly survives.
And I don't think the French are doing too good either on the whole, none of the middle eastern companies are too hot either (Kia, Daewoo (know owned by GM) and several others).
Toyata and the VW Group are quite healthy. And BMW seems to be doing well.
Ahhh so what. Not like it really matters. I'm going to start a car company some day and I'll ally myself with foreign originated companies. Why? Because they know what they are doing.
Did I mention that all gasoline-burning-engine-powered car company's are in trouble every day if we find out there is no more oil? They wouldn't have the money to back the research/engineering/design/marketing of new electric or any other non-gasoline cars.
I gotta say , that new Challenger concept is dayum sexy ! I would love to see it up close , preferably behind the steering wheel on a nice straight stretch of interstate.I've owned different cars from the Big Three and always been a GM fan but Dodge pretty much stayed in 2nd in my book.
