I have an OEM all weather cargo liner (black) that fits a 4 series gran coupe. Part number is 51472357149. It is the one being discussed further down in this thread

I no longer own a F36 so I have no need for it. Condition is very good. No cuts or deep scratches. Local pickup only near zip code 32246 because I don't have packaging material big enough to ship the cargo liner. Selling price is $75. I paid $115 at Tom Bush + taxes.
