Sun shield snapped off.
Air conditioner compressor broke. Fixed under warranty (thank God) would have cost £750, but it had only done 5000 miles at the time.
I like the car despite its woolly performance and handling. It feels solid and safe. To get any sort of performance you really need to stir the gears or buy a turbo. Comfortable for long distances and excellent stereo.
Front tyres need replacing after 12,000 miles.
I have no idea what you do with your front tires as mine last for about 60000 miles. I have 210000 miles now, and had a new set of tires twice (with a front rear change). Quality of the '97 900 is great, performance of the 2.0i not very saab-like.
