Re: For winter tires, look at 16 rims. (more)
IIRC, you have a 2.8 coupe. If so, 16" rims were standard, 17" were optional with the sport package . If you're going to go with a dedicated set of winter wheels/tires, look for somebody trying to get rid of their 16"'s. They should be going for a good price, they'll be better suited for snow and the rubber will be cheaper. Hat trick!
