1990 Saab 900 Reviews
The selection does not include my year a 1986 900 model. Well built with few bells and whistles. Only a buzzer when key remains in ignition switch. Normal wear items replaced. Extremely solid construction. Door panels have screws that allow E-Z access of window regulator that will never fail because it is manual with hand crank. Glass sealed head lights that don't fade after years of driving. Not too many around though.
I had the 900 turbo for 6 years from 1999 to 2005 and it was a complete disaster. It worked maybe half the time I owned it. I had to replace the head gasket, the exhaust manifold gasket multiple times, 2 turbos...it's a very long and expensive list. Eventually the rings on the motor blew and I got a new motor from a salvage yard.
Also, there is a vent in the hood which somehow allowed rain water into the passage for the wiring harness into cabin and flooded with 4 inches of water inside over the course of a couple of days while it was broken down in my driveway.
That said, when the car worked, it was really fun to drive. It was pretty fast and handled well. With the rear seats folded down, I was able to move my apartment including mattress). I miss driving it but not fixing it.
