Whats wrong with red??? Costs more to do jambs, etc, when changing colors.
I have owned a few black vehicles. And before I bought each one I said, "I'll never buy a black one again" They are some of the nicest looking when clean. I WILL NEVER buy a black truck again.
But, have a black firebird.... definately, if the chance came up. How often does it really get dirty? A "California Duster" keeps it clean between washes. And as said previously make sure the body is nice and straight because it will show any imperfections.
