Recently workers at the AutoAlliance International plant in Flat Rock, MI were visited by none other than car legend Carroll Shelby. The 82-year-old don of all things fast just wanted to stop by and express his appreciation to the people who built the Shelby GT500 prototypes that bear his name. The article describes exactly how geeked the workers were to meet the icon. We're guessing the length of the visit was kept to a minimum, however, since the Mustang's popularity has shifted that plant into overdrive. Still, a cool gesture from a cool guy.
