I'm bored @ work, so I'm updating posts.
I ended up winning a set of the saab accessory BBS snow wheels/tires on Ebay for ~$100, but the seller went-ahead and sold them locally. (Doucher)
After some searching, I found another listing in NJ for a set of elbrus I04 with 3k-mile old general altimax arctics. I figure, I'll drive the wagon through this winter on the snows, and then toss the wheels on the 9-3. they're 16x7.5 so they should clear the aero brakes, and not cause problems with the 9-3 when spring comes.
wheee!
