The Buick Skylark Gran Sport was the first Buick muscle car introduced by the car maker. Released in 1965, GS became known for its powerful V8 engine, upgraded suspension, and other performance enhancements.

Released during the second part of the 1965 model year, the Gran Sport option turned the two-door Skylark into a veritable GTO challenger. But, while it never managed to outsell the highly popular Pontiac, the 1965 Gran Sport laid the foundation for a high-performance program that culminated with the 1970 GS Stage 1.

The 1965 Buick Gran Sport emerged as a formidable contender in the muscle car arena, a testament to American engineering and a symbol of raw power wrapped in elegance. Born from the stables of General Motors, this vehicle was Buick's answer to the burgeoning demand for high-performance cars.
