I have extensive chipping of the paint on both the hood and trunk BMW logo medallions on 2006 X3. I would like to replace them and have seen various sites on the internet that offer replacement logos at many different prices. Not only am I not sure which ones are the legit BMW replacement parts, it's hard to determine which ones will fit and what additional parts I will need as some also say I need to buy grommets separately to install. Any help on locating the authentic part and right fit would be greatly appreciated as these logos are the only eyesore on an otherwise well kept vehicle. Thanks.
