I can offer an opinion not yet seen in this thread. It comes down to tolerances. My father works for GM as a tool and die maker. He says that GM is obsessed with tolerances in their panels. This means that the gap between the hood and front quarter panel is the same near the windshield as it is near the headlights. Same goes for all other areas of the car. It's hard to get right.

My friend is a Ferrari mechanic and he says the panel gap and fitment is atrocious, he claims that part of the construction is mostly done by unskilled labor.

It's economics and marketing, in my opinion. Car manufacturers find it hard enough to make money that I don't see them mass manufacturing risky designs that only a small number of people want to drive.
