There's a CO Exige with gold wheels in Hong Kong. The owner posts here from time to time. I'm sure someone from the COM can point you towards more photos. They'd have to be gold powdercoated - I'm sure chrome plating would cost too much for the novelty.
I read your description while the pic loaded and was ready to laugh (at, not with) - but your chop looks pretty cool. I agree with the comments that you want to keep it a little darker/muted. The car in post #8 looks pretty badass. So, why not?
