GM took a good brand with unique (if quirky) cars and put it homogenous corporate stamp on Saab. Bland and no longer unique cars resulted in lackluster sales. They dropped a bulletproof engine from the mid-eighties for a crudy GM V6 and otherwise cheapened the car while trying to sell it at premium luxury car prices. Now GM finishes the job with veto on transfer of patents.
Before GM owned Saab I was a fan, and owned a couple of great Saab cars. After GM I had a 2000 9-3 as a company car, it wasn’t a good car anymore. Last Saab for me and most of the other Saab fans have gone elsewhere a long time ago for new cars.
