I'm with mickjaguar on this (but then I would be, wouldn't I?) - Glacier White with black (well carbon fibre) accents. Typical Jaguar understatement, until you open the throttle - what a hooligan of a car!
I went for the fixed spoiler as the "up at 70, down at 50" in the coupe is too obvious for speed limit breakage. The softtop is a bit better at 60 up and 40 down.
I'd post some pics of mine if I can figure out how to.
