Another model taking a name from racing, the Pontiac Grand Prix launched as an exclusive 2-door hardtop model in 1962. For 1969 Grand Prix received its own body on the smaller A-Body platform. Trim levels included J and SJ trims in a nod to the classic Duesenbergs of the 1930s. Innovative Pontiac Grand Prix parts included an industry first antenna embedded in the window glass and flush-mounted door handles. Besides a one year only convertible in 1967, the Pontiac Grand Prix was only available as a coupe until a sedan model came out in 1988. When the Grand Prix was redesigned one last time in 2004, it was only sold as a sedan. The final Grand Prix cars were available with a 5.3 liter V8 but were effectively replaced by the new G8.
