I owned a Saab 900. I bought it from a a young man at my church that needed money for a missions trip -- and rather than sell it, this summer I gave it away. It had 170,000 miles on it when I disposed of it. Here are some common Saab problem, all of which are well documented and discussed on various fan websites (
www.saabnet.com is the most prolific) and all of which afflicted that car at one time or another . . . .
Transmission will fail between 100 and 150K miles. This applies to manuals AND automatics. Mine was a 5 speed. The remedy? Put in a junkyard transmission and hope for the best, or spend $$$$$$ on a rebuilt.
Heater core leaks and heater control valves fail frequently. Crappy plastic parts combined with a bad design are to blame.
Drivability gremlins (idle control, surging, etc) will crop up frequently and you need to have a mechanic familiar with Saabs to diagnose and repair them. I hope you like him, because you'll get to know him well. I got a tin of cookies in the mail from him at Christmastime.
Plastic bits will disintegrate and fail with age (seat belt latches, dash board, trim, etc) and the headliner will let go.
Fuel economy is nothing to write home about for a compact car, ususally low to mid 20's.
On the plus side, the steel is thick and heavy, giving the car the feeling of tank-like security. The hatchback body style is practical, and the seats are firm and comfortable.
Overall -- fit and finsh, parts quality, and reliability are not anywhere near comparable to a Japanese or German (or even, frankly, an American) car. This is reflected in the extremely cheap resale value -- that's why you can buy a car that was over $30,000 new, for $2,500 (meanwhile, a same-year Lexus would probably be worth over $10K). In my opinion, people put up with this because of the image of driving a "unique" or "anti-establishment" car.
When it is said you need to "maintain" this car, that's an understatement . . . and a euphamism for "this car is an inherently poor quality and unreliable design, and something will practically always need attention from a Saab specialist". Be sure to set aside a recurring allotment in your budget.
These cars are rolling proof that Socialism didn't work. When you build a crappy product you deserve to lose out to the competition. In the '90's, GM had to come in and buy out the company . . . despite subsidies from the Swedish government, they were losing millions due to their well deserved poor reputation. Even today, Saab sales are a fraction of their competition.
I'll never own another of these shoddy Swedish tanks.
Just my $.02 worth.
