I actually have an 03 9-3 Aero. Mine is the sentronic (with flappy paddle thing) but I test drove the 6 speed manual as well.
Good points...
not all that slow really (but by no means fast)
Very comfy seats
Can be modded quite easily. for around £550 you can have ~250hp
Bad points...
Made out of cheap plastic
Fairly low spec as standard
Harsh ride
A lot of people rattle on about torque steer and FWD and so on, but tbh, I don't notice much TS at all (although I did on my old 200hp 1999 9-3, lots

)
I paid just over £12k for mine, it had 35k on the clock, full grey leather interior (most are half leather), dual xenon headlights with Power Wash (little jets pop up and wash the lights

), Sentronic (with paddles which were an option, I believe), Sat Nav, ES3-13 300watt 6 Disc changer "infotainment" system, rain sensing wipers, autodimming rear view mirror and so on. Some of these are obviously options (ES3-13, Autobox, Paddles, full leather and I think Xenons) some may well come with the car (not sure about RSW and ADRVM).
Personal views... My wife really likes it. I have reservations, but that may be because if I'd had the chance of being carless for another 6 months, I'd have been able to buy an M5 or S-type R or something as I'd have had another 8k or so to play with or it may be just because Saab have made them out of cheap plastic which is a bit of a let down when compared to most competitiors.
