You can only find 500 of these cars in the world. Why? Because only 500 of these cars were made by Ford and John Cena is the proud owner of one. These cars were based on the Boos model that Ford Mustang produced in 2007; however, they lack the Boss badges. Saleen Parnelli was the racedriver who drove a Boss 302 on his way to winning the SCCA Trans-Am title in 1970. The limited-editions are how he wants to remember the car that gave him the victory. The dashboards of each of the 500 cars were hand-signed by him. You can find one of these beauties tucked away in Cena’s garage.
