Ford’s enlisted the help of some big names to promote their newest crossover. The Flex hasn’t seen the hottest sales since it hit the market, thanks largely to the overall down turn in the market. Whether or not the tuning crowd will have what it takes to rip the crossovers off the lot remains to be seen, but Nelly and Funkmaster Flex (get it?) were on hand today to help peddle the customized rides at SEMA. Nelly himself handed over the designs for the Flex you see above, complete with massive rollers and wicked front splitter. Only at SEMA, sirs. [Source: DriverSide]
