The 1970 Buick GS stands as a testament to Buick’s peak performance during the muscle car era. When General Motors lifted the restriction on engine displacement above 400 cubic inches in mid-sized models, Buick wasted no time in developing a robust 455 cubic inch motor for its Gran Sport line. This 1970 Buick GS 455 Convertible has been meticulously maintained and appropriately upgraded over time. Resplendent in its original Silver Mist Metallic exterior with a black vinyl interior and a sleek black cloth power top, this GS boasts a correct 455 cubic inch motor, although not original to the vehicle. Rebuilt in 2016, the engine bears the casting number #1231738, ensuring proper performance and authenticity. Equipped with upgraded Wilwood 4-wheel power disc brakes featuring hydro boost, power steering, and a smoothly functioning power convertible top, this Buick GS 455 offers both style and substance. The black interior exudes elegance, featuring newer carpets and a well-preserved dash gauge cluster. The vehicle’s underside, including the floors and frame, exhibits exceptional solidity with no signs of corrosion. Engage the ignition, and the mighty engine roars to life, effortlessly propelling this Buick down the road with its smooth power delivery and ample torque. With its enhanced braking system, it offers precise stopping power when needed. This 1970 GS 400 Convertible is not merely a gem for Buick enthusiasts but a coveted find for any true muscle car aficionado.
