I guess I'm somewhere inbetween the always drive it and never drive it points of view.
I like to drive mine daily, and when I do it gets the same care I give any other vehicle. Wash it if it looks offensive....
But I've been hit a few times by people who don't understand that their driving should adjust for weather conditions. Repair panels for my Suburban are hard to come by and the other guy's insurance company is often painful to deal with, so I don't drive when weather or road conditions increase the risk of someone's stupidity causing me lots of grief.
