In 1965, the Skylark Coupe was called upon to create the Gran Sport. Soon thereafter, engineers worked diligently to shoehorn in the biggest block ever seen in a Buick, the mighty 455 cubic inch V-8. Rated at 345 horsepower and 460-ft/lbs of torque, this 455 GS is noted to be correct with the correct drivetrain. It has a 400 Turbo Hydra-Matic transmission, 3.42:1 gears, limited-slip differential, power steering and power brakes. The faultless interior offers tan upholstery, bench seat, sport steering wheel and an AM radio. The light copper exterior is adorned with a tan vinyl top, factory five-spoke chrome-plated wheels, Goodyear radials, and exceptional trim and brightwork. A full body-off restoration on this GS has created a stunning show piece that is one of only 801 Stage 1 GS coupes built for 1971.
