The Buick GSX is a high-performance version of the Buick Skylark, a personal luxury car produced by the Buick division of General Motors. The GSX was a version of the Buick GS455, also a high-performance version of the Skylark; a prototype was shown off initially at the 1970 Chicago Motor Show to test consumer reactions. The GSX was intended to compete against cars like the Pontiac GTO "The Judge", Oldsmobile 4-4-2 W-30 and the Chevrolet Chevelle SS; produced late in the 1970 model year, 678 were produced for 1970. For 1971, the GSX became a package available for all Gran Sport models.
