"Car Guys vs Bean Counters" is a VERY good book.
Bob Lutz (of GM, Chrysler, Exide, Ford, BMW) talks about how GM analyzed and brand-managed itself into a hole by leaving product development to MBAs, analysts, marketing executives, and accountants instead of the creative types with a passion for automotive design. In the book he admits to several of his own mistakes. I'll post a review of it in a week or two.
"If you want intelligent people, boy, GM is loaded with them. Common sense gets left aside."
Watch the video for an overview. He criticizes the Aztek, the Envoy XUV, and canceled projects like the 7-passenger Saturn Vue which would have been the same vehicle with the addition of a massive rear overhang.
