2005 Ford Mustang
5 of 9
Sales of the original pony car were languishing when Mays, now a Ford group vice president, directed the styling of the 2005 Mustang along the lines of the fastback models from the late 1960s. Some sources attribute the actual look of the exterior to an industrial designer working at Ford named Sid Ramnarace, but the proportions -- long hood, short deck -- came straight from the retro-futuristic playbook. Afterward, Mays liked to joke that he was glad not to be remembered as "the guy who screwed up the Mustang."
