The 2019 Shelby GT-S was a limited edition GT-series Mustang, produced by Shelby American, for rental through SIXT Rent-A-Car. Only 21 such Shelbys were produced, one of which was gifted to SIXT’s CEO, Sebastian Birkel. With their rental, consumers were able to slide behind the wheel of a true American sports car, complete with a 600-horsepower supercharged V8 beneath its hood.
