The Buick GSX from 1970 to 1974 was Buick’s flashy response to the muscle car craze, boasting slogans like “Light Your Fire Cars from Buick.” Originally adorned only in Saturn Yellow or Apollo White, it packed a punch with a 455 V8 engine and optional Stage 1 kit, producing 350hp. Enthusiasts argue whether it could outpace the Hemi ‘cuda. Fancy a rare Stage 2? Look for Edelbrock B4B intakes and “Kustom” headers. Auction prices hint you’ll need deep pockets for this classic—maybe even a spare kidney!
