I've always been a 'less is more' type. Function over form, I guess. My last car was a black E92 335, I opted for a black anodized FMIC for the stealth factor, swapped out the chrome badging on the trunk for black, etc.
The only sticker/decal I've had on any of my cars is attached.
Putting fake badging on cars, not sure what drives this. Is it wishful thinking? Looking to the future? *shrug* I'm finally to the age at which I could afford my new used M4, and as I move down the mod path everything will be as subtle as possible. Because that's what I dig. And no stickers or Ferrari badges.
