In the GM brands hierarchy, Buick was surpassed in luxury and comfort appointments only by Cadillac, which did not produce performance models. As a result, the Buick GS series were the most opulently equipped GM sport models of their era. GSX / GSX Stage 1 was Buick's contribution to the Classic era American Muscle car list, based on the GS455 which was in turn based on the Skylark platform adding an appearance, performance and handling package available starting in the 1970 model year. The GSX Performance and Handling package was a $1,100 option on the GS455 ($8,907 in 2024 dollars) in addition to the listed retail price of $3,098 ($25,084 in 2024 dollars) for the Buick Gran Sport which the GSX was based. The GSX was Buick's attempt to increase showroom traffic on a newly designed Skylark body style for 1970 which started off slow but sales improved. The GSX was Buick's answer to Pontiac's GTO Judge, Oldsmobile's 4-4-2 W-30, and Chevrolet's Chevelle SS. Buick advertised it as "A Brand New Brand Of Buick" and "Another 'Light Your Fire' Car From Buick". It came standard with a 455ci engine with or without the optional Stage 1 performance engine upgrades during the first year of release. Although near the top of GM's brand hierarchy, the GSX hardtop's basic bodyshell was the same as the lower-priced 1970 Chevrolet Chevelle but with differing guards, grille, bumpers, doors, etc., while Pontiac and Oldsmobile midsize hardtop coupes shared a slightly different body.
