The 1969 Buick GS 400 Convertible combines rarity and performance with Buick’s luxury touch. Powered by a 400ci V8 rated at 340 horsepower and paired with an automatic transmission, it delivers smooth yet muscular performance. Showing just 640 miles since its restoration, this GS 400 remains in excellent condition and is ready to be enjoyed. A fine example of Buick’s late-’60s muscle convertible, offering both power and collectability.
