Consider myself kind of a car guy. Currently own a black Focus RS. I would never run it through a car wash. Since we live in SoCal it doesn't get dirty often, but as soon as it gets dusty/dirty, it gets washed. I do cheat now and use a waterless wash product. So much easier than dragging out a hose and bucket. I've been using this:
Optimum (NR2010Q) No Rinse Wash & Shine - 32 oz.
