I have had no less than 4 black motorcycles, 3 black pickups, and now own a black Mustang GT. I also live 2 miles from pavement. Wouldn't have it any other way. I have also had some other colored vehicles, including white. IMO; all the other colors look worse than the black when crapped up. White looks cheap, greens and blues show the crud just as bad if not more than the black does, and looks shittier. The worst thing to do to the black is to over do it with chrome. And I see a lot of bikes and pickups that have done just that, and to me, that looks gaudy as hell.
But then; all of this is just my opinion, so it really doesn't matter anyway. If ya like black, go for it, and don't worry about what others think!!! Even if it gets dirty from time to time.
