I'm looking at buying a 2015 QX80. I have a Platinum Nissan Armada and I'm looking to upgrade to basically what is the luxury version of what I have. I have seen a couple for sale at dealerships with blacked out exterior trim, such as the rims, side vents, Infinit logo and lettering, etc. There is no chrome exterior trim, it's all black. My question is did the factory make this an option or is this all after market? I like the look but should I be concerned as to how long it will last, will the black chip away, etc? Thanks in advance!
