I contacted BlueBat, the famed vinyl creator for G35s, etc. about making Smoked Vinyl Overlays for the E90 Sedan. These would be the same type overlays Hunter previously offered.
I know that group buy fell through and there are still alot of people that want them and no other vendor currently offers smoked overlays.
Bluebat stated that he needs a car in the San Deigo, Cali area to measure and size the overlays.
Here is a link to his gallery page where contact information is:
