Personally, not too keen on the GTD or the GTI wheels, i find the black look far too glossy (like Vauxhall's), and the 19's look very busy. I've seen all 3 on GTD's and GTI's today at Peterborough VW. I thought the GTD would be more anthracite looking, by going by the brochure, but hey, i was wrong, again lol.
Maybe i'll keep the GTD wheels as spare and put some BBS CH-R's on instead.
