Saab Information Display pixels do not display correctly (this seems to be a common problem and is easily fixed with a new unit).
Alarm can act up in damp weather.
Comfort is the key with this car. Big supportive seats that work very well for tall drivers (I am 6' 5").
The car is very quiet too and as a second hand buy at about 6 years old represents fantastic value for money.
However... performance on the standard non-turbo version is pretty sluggish.
If you can find/afford a good LPT version or even the 2.3 I would suggest this is a better bet.
Actually it is not me, but my cousin that has a 1998 9-3. His is a diesel hatch with a manual gearbox, and from what I've heard, everything above is true.
