Hey! I would have changed mine from arctic silver to midnight blue (with sand beige) having seen the launch cars! The only reason I didn't was that I guessed it would be too late to change for Feb 05 build. I was right, because I wanted to add Park Assist and couldn't.
I don't believe colour coding is an "official" option but the dealer told me that he could colour code the centre console if I wanted it, as that option was not available in time for me to spec it officially.

Colour coding? I think I would have left them, because if the side vents are colour coded then I guess to look right the front ones would have to be done as well.
