Auto City Classic - Gran Sport

The Buick Gran Sport — also branded GS, GS 400, and GS 455 — was Buick's muscle-car answer from 1965 through 1972, built on the Skylark and Sportwagon A-body platform. The Stage 1 cars from 1969–1972, with the 350-horsepower 455 V8 and 510 lb-ft of torque, are among the most underrated American muscle cars.
