Just because Neidfaktor has built a reputation on custom-tailoring Audi's interiors, doesn't mean they're neglecting the exterior of Ingolstadt and Neckarsulm's finest.  The latest example of this, is one particular Nardo Grey RS 6 featuring subtle body modifications, used to showcase mbDESIGN's KV1 wheel in 22 x 10" ET20 and 22 x 11" ET23.  As with most projects to come out of Neidfaktor's shop, this RS 6 is something we'd gladly park in our garage.
