I have a 100 mile round trip commute every day, and the crossfire is my daily driver. I live in northwestern NJ so drive up and down hills, on winding country roads, interstate highways and city streets on my commute. I don't have a choice to not go to work when it snows as I work at a hospital. I have NEVER had a significant problem with the car in the snow.

I have a set of 4 OEM 18 inch wheels with blizzak snowtires. I put about 120 lbs of weight in the cargo area. Put the W/S switch in W. And Drive. I do turn off the T/C when I go up a hill, as I find it easier to use my right foot to control the traction and maintain momentum going up the hills, but other than that, the car does just fine in the snow.

A light foot on the gas, a light foot on the brake, anticipate the traffic and you should have no problems at all...
