There is very little that has not gone wrong with this car. I paid it off in the first year, but have been paying a fortune to maintain it ever since.
Do not buy one!!!
You are right never buy a junk. Always buy from a reputable Saab car dealer, cars that are not fit to drive should go to junk yard. Saab can travel 100+ mph easily, so car that are not properly maintain should be avoided at all cost, you don't want to lose any life just to save few bucks..
