The Shelby GT350H Mustang was a special version created for Hertz Rent a Car. There was stiff competition between Avis and Hertz to be the number one rent a car company and anything to get attention was tried. This was the era of muscle cars, and racing that was sponsored by the big three or four it was thought would reflect well with a rental car. Hence Hertz decided to rent these fabulous high performance cars. It was understood that the customer would not race them. Never mind, many customers did just that but kept it a secret from Hertz.
