I just purchased a 2004 Crossfire and I love it. I drove it yesterday from Minneapolis to Winnipeg (Canada) while the roads were very icy. The Michelin Pilot Sports on the car might as well have been steel - definately no traction. Once I was in my yard I parked it for an hour (outside temp. 8 degrees F) and once I wanted to move it on the snow it would just sit and spin. When I left Minneapolis it was 36F and the tires had plenty of traction, but once it got down to 15F I couldn't stay on the road.

Last week I drove a car with the Continentals in 2-3" of snow and it did quite well all things considered.
