GSX / GSX Stage1 was the optional high performance package available on the GS 455 starting in 1970. The GSX was Buick's answer to Pontiac's GTO Judge and Oldsmobile's 4-4-2 W-30. It was only available with the standard big block 455 engine or the optional Stage 1 engine the first year. It was not a very popular model and not too many people bought them, and only 678 GSXs were produced in 1970.
