From the linked article, Saab had a highlight of sales at 48,000 and change in 1986, when they were a post-recession yuppie fad. They were always bad cars, and articles like this one reminiscing about the "glory days" of Saab are a bit myopic. They rusted out in key places, like where the control arms for the front suspension bolts to the body. They're a nightmare to work on, with the engine spun backwards in the engine bay. The "tight steering" meant nothing when coupled with a body that flexed terribly, especially on the convertible models. Big buttons for people wearing gloves? That's the best contribution the author can come up with in his requiem?
The fact is that people don't want to spend huge money on mediocre cars. Saab was purchased to be placed in GM's lineup as a luxury foreign brand, much like Volvo's purchase by Ford. The new cars were built on better platforms than the ones Saab could engineer, with all the quirkiness still intact for buyers with too much money and not enough common sense. That GM can't give the company away, and can't make money selling weird cars is proof of this. The year GM purchased Saab they killed off Oldsmobile. Saab was selling ~40,000 cars per year, Olds was selling 250,000 cars per year. They killed a brand that made them far more money in order to have a more upscale image, only to find out what people really imagined the cars to be. They made a Saab out of a Blazer, they made a Saab out of a Subaru, and I'm sure if some marketing doofus thought it was a good idea they would have done the same with a Daewoo as well.
Saab had some interesting ideas over the years, but they were cars that were constantly broken and difficult to work on. I've spent many years as an auto tech and diagnostician fixing these things. I'll always have many fond memories of working on Saabs. They've brought me so much laughter over the years.
