Go for Reflex Silver. One of THE best colours for the mk7 IMO. Red stripe looks great against it. Will hide swirls and look superb when clean and detailed. Beautiful colour. Stick with the 18" Austins, the Santiagos too fussy looking. Austins not exactly a classic like Monzas but nevertheless a good simple design works better with the lean lines of the car. DCC is not the be all. I'd happily skip it even on 19s.
