The 2012 BMW 6 Series Coupe has received a new, sinister styling package from the guys over at SR Auto Group. Eerily (and a bit over-the-top dramatically) introduced by the tuning firm as "Dressed in a cloak of black, the Shadow Walker reveals itself through the haze of fog," the 650i Shadow Walker was specially prepared for a single client and features a slick matte black exterior finish that combines well with a set of big blacked-out 20-inch aluminum MHT Niche wheels.

The interior has also been touched up a bit, with extra touches here and there on the dials, steering wheel, etc. SR Auto Group has stayed mum on how much the 2012 BMW 6 Series Shadow Walker costs, though if you are in the market for a very aggressive and unique Bimmer, price might not be too much of a hindrance here.
