If I was just going to get a car for daily driving, or snow beater, then any of them would work. If that was the case, then I agree with Saaboost and Bosz13. The mid-year 95 (or a 94 with the contral arm upgrade) would be even a BETTER bet than the later ones because they're so inexpensive....You can get a high-mileage one for under $2,000 up here, and at that price, they;re basically disposable. Run it into the ground, run it into a moose or over an embankment, then get a new one...
If you're going to upgrade the power, you'll eventually need/want to upgrade the clutch and the hydraulic is definitely the way to go for handling power. The switch was one of the first things I did with my 97, because I commute 40 miles each way to work, and I knew my cable would break at 2 a.m....along a dark highway...in freezing rain.
...and if you're upgrading power, you'll eventually need/want to upgrade brakes. All 9-3/9-5 after 97 use the same size hubs front and rear, so you can inexpensively upgrade your brakes to the large ones found on the Viggen or 9-5 Aero...or the even larger ones found on the 06 9-3SS Aero.
