Smokin: you may have the time to clean your cars with intense detail after a winter drive, but most people don't. I know I don't. Even if I did have the time, I wouldn't want to put in the effort for such a small return.

Besides, there another really BIG reason I store my car in the winter: THE OTHER DRIVERS! People are idiots and can't drive in bad weather. I'm not wrecking my car because some jag-off doesn't know how to drive.
