GM's biggest money making division is GMAC. They are now a finance org whose secondary focus is automobile manufacturing. They have totally forgotten what their primary industry should be, making good looking, functional and desirable autos the public likes.
I have always thought that the decline in GM started when they made common size cars between divisions look the same. The Chevelle, LeMans/GTO, Buick Gran Sport, etc. This is precisely when bean counters took over and put the CAR people in the back seat. I think this is why Lee was so successful at Chrysler, he was the last of the car guys to run a major auto company in the US.
Last but not least, I think when GM got rid of Fischer Body Division was the decline of the GM styling and fit and finish quality.
1. A new Kia Optima for $X
2. A year-old Ford Taurus with 24K miles, at the same price
3. A new Chevy Malibu, an ugly, uncomfortable pig I wouldn't have considered unless it was priced at least $3K UNDER the Kia. Guess what, it was priced $3K HIGHER.
Guess which one I bought.
