By now every car lover knows who Carroll Shelby was, but what makes his cars so great? To find out, we headed to the Autoclub Speedway in Fontana, California, where the Shelby American Automobile Club was holding its annual Shelby Convention. We talked with racers and collectors, and got a chance to ride in a GT40 with a man who raced for Shelby back in the days, High Performance Driving School founder, Bob Bondurant. We also were on hand for the debut of the newly restored Essex Wire Cobra, one of the winningest big block Cobras ever to compete. We also take a look at what makes driving these cars special, and why people come from all over the world to see them in person, and hear them on the track.
