So after running out of patience for the "official" performance grille to come out for the M340, I replaced mine with the "sport" grille and sent the original off for painting. The outer cerium gray to be painted gloss black while leaving the diamond mesh as is.
In the interim they finally did release the grille, but it's completely gloss black, which is OK, but I wanted a little contrast to mimic the M340i I first fell in love with before I ordered the car.
She goes on this weekend, more pics to come!
