I've ordered AW with delivery this Summer and the grills will be one of the first things to modify.
I've mentioned it before but I won't be fannying around scraping knuckles and forearms with the bumper loosened off as it will be straight out with the hacksaw on the first and then reaching in and popping out the second.
Personally I'm not sure about the chrome on any colour as it's not anywhere else on the car unless one opts for the chrome highline which is a no-no in my books.
EDIT:
Chrome is on the exhausts of course,but that doesn't count
