From the 1959 Bonneville to the 1969 GTO to the Firebird T/A, Pontiac was a legendary car company. Nothing said performance like that arrowhead logo on the hood. Like all American car companies, GM lost it's way by the 1980's and forgot about the "main thing." You had a bunch of Harvard B-school pricks running a car company. They drove BMWs of course and too many of the white collar and union guys were buying Toyota's.
Lot's of blame to go around, but this is what we are left with in 2009...lots of blame and no leaders.
If this didn't work for you, there was just no hope:
Marketing. Man this is marketing.
