It's basically the rear passenger windows and back window all dark tinted. (not allowed for the front passenger windows to be tinted in the UK). Really like the look it gives off, and especially wanted it with the SG, black wheels, exhaust etc. Negative being i may look like a drug dealer!!
Yeah i had that Piano black in the M3, really liked it. But yeah can be a OCD nightmare.
But i don't tend to have pets or children in my car and if any adults do, they have to wipe their shoes before getting in and keep their hands in their pockets!!
