1991 Saab 900 Reviews
I have had my Saab 900 ( 1991 ) for about two years and have had a handful of issues with it. These cars seem to have a cult following behind them, everyone you see that drives one seems to nod or give a slight exchange of eye contact when in passing. Issues with the car have included--the cooling system ( i . e . hoses, thermostat, grounding sensors ) , The ignition system and alternator and more grounding issues. Considering I myself have only four years wisdom over this car I cannot complain about the small things, the 900 still drives fine, the check engine light is on, but mostly all areas have been checked for issues relating to the problem. I do nearly all of the work to the car by myself, its an alright ride though.
My experience with my Saab 900 SPG was really good. It looked and handled really good. I had the water pump fail but otherwise I had few problems before I sold it for a bigger car. I miss it!
