In reply to drunken monkey: I can't speak for the 9-3, as I've got a Saab 9-5 Aero Estate (2004 model). It's my second Saab and I love it - spacious, immensely comfortable and capable, and tons of overtaking power when you need it. I also use it for towing and the car has so much power that it's easy to forget you're pulling anything behind you.
It is thirsty on fuel (30mpg on a run), and since owning it for the last 8 months I have had some problems, all of which I hope are now sorted. These problems aside, I have no hesitation in saying that it's the best car I have ever owned.
In winter it is superb; the traction control does an incredible job of keeping 250bhp at the front wheels on the road without spinning all over the place. Great space in the back for the kids, full leather, heated front seats are lovely first thing on a cold morning, enormous boot, and all the usual Saab quirkiness (key by the handbrake, fantastic cup holder) to boot.
I did consider a 9-3, but preferred the look and extra capacity of the 9-5, and that was all. I don't think you'd be disappointed, just don't expect it to be as cheap to run as your Golf!
