That's one super shiny, wet look GTI (and A1). Top job! Really like the anthracite Watkins Glen wheels.
Black looks fantastic after a good clean, polish and wax, but having had 5 black cars in the past, I know what a labour of love it is to keep them looking that good. I've had white too, and like both, but I think white is easier maintain if you're short of time.
I find my Carbon Grey GTD seems to stay looking cleaner for longer than my black mk4 and mk5 did. Seeing your super-clean pair has put me in the mood to do my pre-winter detail, once the weather improves!
