It's a bit of a mystery, but somehow, Classic Automotive in Queen Creek has become a go-to shop for the Arizona DeLorean Club, a group of enthusiasts dedicated to preserving the stainless steel coupes manufactured in the early '80s by a long-defunct company and used as Doc Brown's time machine in the Back to the Future trilogy. Only about 9,000 of the cars were ever made, but about two thirds are still on the road, owned by collectors who need to take them someplace special when they need repairs. Classic Automotive, a small and attentive shop, is that place. If it's good enough for a DeLorean, it's good enough for your Ford Tempo — or so they seemed to be suggesting, when they turned their two-week gig repairing a replica of the movie car into a full-on promotional campaign, complete with fliers bearing the auto's image.
