I'm looking to buy a 2004 Cadillac CTS. I live in Buffalo, NY and was wondering how good they handle in the snow. What model, base,sport etc. has the button for winter driving(more traction).
Why oh why are you planning on driving a rear-wheel-drive car in snow? There is no such thing as a "button for winter driving", especially on RWD cars, which just slip an slide on anything OTHER than tarmac, especially one as powerful as the CTS. You'll just spin the rear wheels constantly, come to a corner and just slide right off the road. Get an Impreza WRX STi and some snow tyres, at least you won't get yourself killed.
