On 7/6/12 in Rutland, MA, I saw a AC Cobra 427 . I LOVE Cobras. They were made when a car company called AC teamed up with Carroll Shelby, a race car driver from Texas. Ford supplied the engine because GM didn't want to help the development of a car that could compete with the Corvette. The 427 was the most powerful original one. The one I saw was green and had a small roll cage over the driver seat.
