“The Velvet Hammer” The Buick GS-X was one of the most overlooked muscle cars of its day. Buick had a reputation for building old people’s cars and high-end personal luxury cars like to Riviera. Built on the same chassis platform as the Chevelle, Tempest, and Cutlass, the Skylark-based GS-X was an outgrowth of the overlooked GS-400. The car just seemed like a goosed up middle-age person’s car. But the GS-X was another story.

Packing an under-rated 360 horsepower 455 big-block Buick engine with 510 lb.ft. of torque, this beast could handle almost anything on the street. The overall package had just about everything a cushy muscle car owner might want. It had scoops and front and rear spoilers, cool stripes, a hood-mounted tach, PLUS, it had all that extra upscale Buick trim in the interior. It was like a Riviera on steroids!

But luxury and performance had a price. The GS-X cost over $5,500 - a LOT OF MONEY in 1970. However, with the right tune and driver, a GS-X was capable of 13.5 second ets on the drag strip.
