Has anyone tried to switch there regular Cadillac Escalade grille for the Platinum grille? I have a 2015i Premium Escalade and I am wondering if it would be fairly easy converting the grille to a platinum grille.. And would it need to be professionally installed or is it pretty easy that I could install myself. Also I'm wondering if anyone has the $100 exhaust tip accessory for the escalade? If so can you post pictures from different angles. Thank you.
