My TTS is in the process of having the rear bumper repaired. I've always thought, or maybe I had forgotten it wasn't, Daytona Grey. Repairer called me to say he didn't think it is and a quick look at my car paperwork reveals "Audi Exclusive Colour". I enquired with Audi UK who have told me it is in fact Jaguar Ammonite Grey. Every day's a school day!
