Tricky one. I've never owned the "classic" Saabs because a) good ones are out of my reach now and b) I need cars that can be pressed into daily service. Running an 80s/90s car just wouldn't be practical.
I really enjoyed my '99 9-3 Convertible because it was my first unnecessary car if you know what I mean? Had a couple of 9-5 Aeros but they were a bit leggy and too firm I thought. I'm really liking my current MY07 9-5. It's in good nick, low mileage and it's a bit softer because it's not an Aero. Though I have had it mapped to Aero numbers. But I think the most satisfying one is my MY06 9-3 Aero Convertible. It's just such a good drive. Comfortable, practical, can be used in all weathers and I can get my kids in it.
I'm currently on my 7th and 8th Saabs
