Buy some 17 inch wheels from an slk320 sport, then slap some blizzaks snow tires only on them. Viola, you know have a car capable of going through over 6 inches of snow. The crossfire will plow the snow away with its low ground clearance. But it will go through it. We got 10 inches of snow here in chicago not too long ago, and the crossfire with this setup had no troubles. The whole set should run you only about a grand or so.
