Ok, a little history as I remember it(so basically unreliable).
In the late 80's, GM, Ford and to some degree Chrysler had some cash and were trying to buy into the high end markets by buying up troubled European manufacturers. GM's experience with Saab was always a matter of GM setting the rules, and Saab doing whatever it damn well felt like. The final straw was when Saab basically reworked an Opel design that GM wanted them to just rebadge. When GM sold Saab, they refused to allow all of their proprietary work to be used by Saab at no cost. The price for Saab to rework these systems made the whole enterprise collapse.
