As you say Faksta, GM screwed around with the Saab brand too much and forced horrors on it such as the 9-2X (which was actually quite a good car; but not a Saab) and the awful 9-7X.
Although GM can't be blamed solely for Saab's demise, it played a major role in its downfall (especially as Saab was profitable in the late 1980s). I worked at Saab during the GM regime, and witnessed first hand the unforgiveable mistakes, lack of brand understanding and complete lack of funding for much-needed new products. Rather than invest in Saab, the General always favoured its own brands first, many of which it then subsequently killed of (Oldsmobile, Pontiac, Saturn). I was very involved in some great stilborne Saab projects with promising new models to take the brand into lucrative new market segments (with rivals for the Audi A3, BMW Z3, Mercedes M-Klass, etc.) that were 50%+ complete, before the GM bean counters came in and pulled the plug on all the funding.
As much as I hope Saab will survive, I really fear that now it will not, as GM will not permit the sale of the marque to the Chinese due to claimed interlectual technology rights, and unless the company is sold as a going-concern, SAAB AB (the aviation division) will not allow use of the Saab name for automobiles, as it owns the rights to the Saab brand name. A really shame.
