This week's 1965 Shelby GT350 Mustang represents 43 years of partnership between man and machine. Steve Beck bought this GT350 for $900 on his 18th birthday, hoping to make an impression at his first big job interview as a mechanic. He got the job as soon as they saw the Shelby, and after years of track days, vintage racing, and more than a few speeding tickets, Beck is still going pedal to the metal in the legendary pony car. Say goodbye to parade laps. This is Flat Out, which means you're about to get a taste of your favorite classic cars being pushed to their limits. All it takes is a worthy ride, an open track, and a driver willing to test his or her mettle at the ragged edge.
