My car is a garage queen at this point, but even when it wasn't I used to park it for the winter. Up in the northeast, the salt just EATS cars and my buddies who DD'ed their foxes eventually had to get rid of them due to rotted strut towers and other areas. Even SN95's up here are starting to suffer strut tower rot. I looked at a 2004 GT that had a bad case of it.
I park my car once daytime temps start getting below 50 degrees, and I won't take it out until we've had a few good rainstorms in the spring to wash the roads clear.
Right now it's -1 degree out, and I really need to get to a car wash on the DD. This is why owning a car older than 10-15 years old is rare up here
