Patrick Dempsey drives a Mazda in Grand-Am. He's also into cycling. Both passions become inspiration for Mazda's custom Dempsey CX-5, built for SEMA. It is one of three CX-5s prepared for the show, including the SoCal-inspired 180 (first image) and the sinister Urban. The Dempsey has a slick black and red scheme, the Urban has a dope, monochrome black geometric pattern. All run a diesel engine.
