Forty years ago, Carroll Shelby and The Hertz Corporation came up with an ingenious plan to help get a batch of high-performance, special-edition Shelby Mustangs into the hands of rental customers who also happened to be car enthusiasts. Ford supplied the new Mustangs with V-8 engines and mostly automatic transmissions, Shelby added extra performance and style, and Hertz gave the public access to the kind of unique driving experience that one would normally only find on a racetrack. Today, the story of the Shelby/Hertz "Rent-A-Racer" is legendary and surviving Shelby GT350H Mustangs are among the most sought-after collector cars in the world.
