FWIW, my initial reaction was that you need more red to make it work. The JCW looked OK because of the roof and, to a lesser extent, the bonnet stripes.
The Golf only had the calipers and a slither of red around the grille as accents. I think it needs more - perhaps on the wheels?
But - ETTO and all that. I should admit that my car's only mod is a replacement bottle opener!
