1970 Buick GS 455 Stage 1 Convertible
T he year 1970 proved to be monumental for Buick in developing a truly great muscle car – one that today ranks high in any enthusiast’s list of dream machines. The Buick GS 455 Stage 1 was a far cry from anything produced before by Buick. Although it was conservatively rated at 360 horsepower, most testers at the time believed it was good for some 400 horses, thanks to its massive engine, beefy cam, larger valves and a huge carburetor fed by functional hood scoops.
With all those working in concert, the GS 455 was capable of a pavement-pounding 510 foot-pounds of torque and was labeled by Motor Trend as the quickest American production car it had ever tested, up to that time. Even more astounding is the fact that the Stage 1 performance package was available for less than $200!
Along with its bold and brawny power plant, the GS also provided loads of amenities for its driver in a sleek body and cool trim package. With fewer than 1,500 Buick GS 455 Stage One convertibles manufactured, out of a total run of more than 10,000, this is an exceptionally rare automobile, with exhilarating capabilities.
Also in 1970, Buick produced its visually dramatic GSX version, an even more exclusive muscle machine. Along with the GS 455 Stage 1 performance package, the GSX included aerodynamic trim, hood tach and stiffer suspension, and was available in only two colors – Apollo White or Saturn Yellow.
Only 678 were built with the funky $1,195 GSX package. -Larry Sanata
