Ford has called upon hip-hop star Funkmaster Flex once again to help trick out its 2007 Ford Expedition for next week’s SEMA show in Las Vegas. Flex, who previously worked on projects involving Ford’s Fusion, F-150 and Mustang, will apply his talents to the big SUV to help improve its falling popularity. The Funkmaster Flex Concept features a unique Street Scene bodykit and rides on 24in alloys. To match the flashing accessories, the concept comes with a two-tone black and redfire paint scheme. Inside, the vehicle gets the usual DVD entertainment packs, LCD monitors and a performance audio system.
