Ha, Amber turns a lot more heads than the C63 does, that's for sure! It's only the racket the AMG makes that turns folks heads!!
As for GTI colour, I still can't decide!! I want a Prestige, that I'm certain but I can't choose between Rioja or Satin White. There are already heaps of white motors in the street so I'm swaying towards Rioja at the moment ... but having seen a Satin on here the other day, it does look great! Amber has been hard to keep swirl free so I'm expecting Rioja to be the same, you just don't see marring/swirls on white. There are pros/cons for both!
