GM's demise is utimately the fault of management. Look at the crap they produce--anyone checked out the new Malibu? I would not be caught driving that to a hog killing.
The worst cars I have ever owned were GM products. Starting with the great Chevy Vega with the aluminum block that burnt up after 30k miles and cost this poor college student a fortune. The second was a Monte Carlo that was the worst POS I have ever driven. The only GM car I ever owned that was somewhat worth anything was an Olds Cutlass, but of course the brilliant leadership of GM discontinued the Olds.
The best cars I have ever owned were Japanese made--Mitsubishi, Honda, Toyota and Mazda. My husband just bought a new Toyota Solara convertible for 28k with all the bells and whistles, including awesome styling, and great quality.
GM just does not have the styling and it is too late to get the edge over the Toyota, Honda etc.
I think the pontiac vibe is quite a good car. It does have a lot of toyota stuff in it as it is a joint venture with its twin toyota matrix.
OH, so you never owned an AMC car? These were WAY worse than GM cars for lousy quality. I was spending $400-500 per month to keep mine on the road when I finally wised up and bought my first Toyota.
