GM has no one to blame but themselves.
02'Camaro production was stopped for this POS:
http://en.wikipedia.org/wiki/Chevrolet_SSR
Lots of guys who would have purchased a GM product left the brand after GM left part of its established core loyalty group. (Camaro owners) Many jumped to Ford and picked up stangs and then F-series too...
A senior GM official has been quoted as saying the Camaro "had to go away" It did not have to go away anymore than the SSR had to be produced. This is an example of just one of a series of bad business decisions made that resulted in the GM that we now see today.
Too bad for Pontiac. Another mistake about to be made. Tossing aside Pontiac heritage is going to be a huge mistake for whatever remains of GM.
