Classic cars in cold weather states...is it worth it?

Most of us just dont drive it when the roads are bad.Myn is holding up just fine.The salt they put on the roads is what kills em. I figure my car will last the rest of my life and if i have to fix it i will. it was rusty before i restored it and it looks good to me now.Wouldnt give it up for anything but family.What do you Do when its a hundred degrees in Arizona.
