I leave my car outside under a foot of snow and ice all winter - well, I did last year at least. Maybe this year there will be a car cover between the snow and sheet metal! But I do clear it off every once and a while and drive it when the roads allow.

As for your wheels - I agree that they should probably survive with no issues, but a heavy coat of wax left on should help ensure no problems. Just remember to wipe off the excess before you go drive the car again! Oh, and you might want to disconnect the battery, and possibly keep it on a charger? Or charge it once a month? I dunno - probably need to do something with the battery, and perhaps fluids. Check with the guys here on that stuff. 3 months isn't long, but 5-6 months would require more work I'm thinking.
