Was running an errand in Cranford, NJ on Saturday and I spied the new C-Class testing on the backstreets. Was totally wrapped in black, but it was obvious what it was - the insignia was on the grill, not raised out of the roof - I think this is the sport version. Sorry for the somewhat blurry pictures, took with my cellphone while I was driving.
Enjoy,
