The only concern for me when driving a vehicle is salt. If I don't drive a "nice" car in the winter, it's because I don't want rust. That is one of the few things IMHO that TX has going for it...virtually no rust on the cars down here. So this past Feb, I said fk it and took my nearly mint, built GSX out in the snow and ice several times. My only reservation about doing that up north would be, as I said, salt=rust.
