Some second hand anecdotal experience on owning a Saab. Last year I found a very nice 1987 300E for a coworker. At the time he was driving a Saab - a 900 from the late 1980s. Though he is a reasonable doityerselfer the maintenance/repair costs of the Saab were eating him alive. He spent $5K keeping it on the road in 2000. There are no low cost parts vendors for the Saab market. (His claim, I wouldn't know.)

Anyways, he bought a nice 300E. Says it's a better car in almost every way - smoother, quieter, drives better, more comfortable, more reliable, cheaper to repair - you get the idea.

If you're looking at a brand new Saab under warranty, go for it. If you're talking about a 10 year old car, I think there are better choices.
