The AC Cobra Mark III is the car that put the ‘zoom’ in ‘vroom’ and made Corvettes cry. Born from a British roadster, it was beefed up in Los Angeles with a Ford engine, transforming into a racing beast. Detroit Ford worked with Shelby to craft the Mark III, boasting a 427 engine that could hit 185 mph on race tracks and leave a trail of awestruck spectators. The British government even imposed speed limits after one Cobra hit 186 mph on the M1! Talk about leaving a mark—or a skid mark, in this case.
