Problem is that car manufacturers make very little profit on the cars themselves; in some extreme cases, they even make a loss. There real profit margins are on the parts. I recall back in the 80's someone did a costing exercise on how much a car would cost if it were built entirely from spares, it was something like 10-12 times more than the car itself. That was obviously before the days of advanced electronics in car systems; I wonder what a similar exercise today would show up?
