General Motors and its GMC and Chevrolet divisions were truly on a roll in the highly competitive American light-truck market of the late 1950s with strong sales and market share. Respectively marketed as the “Blue Chip” and “Task Force” lines, the GMC and Chevrolet light trucks were increasingly civilized, stylish, and well-equipped, yet capable of performing hard work while delivering excellent reliability and good fuel economy.

Styling for the 1959 GMC and Chevrolet trucks was heavily influenced by the attractive Chevrolet Cameo Carrier of 1955 to mid-1958, which brought sportier and more upscale designs cues in keeping with GM’s passenger-car lines. Six-cylinder and V-8 engines, useful load ratings, double-wall steel cargo-box construction, and wide tailgates ensured utility to match.

While Chevrolet pickups of the era came with a “Stovebolt Six” or small-block V-8 for power, GMC light-duty trucks utilized the GM division’s “Jimmy” inline sixes or Pontiac-derived V-8 engines. For 1959, the GMC V-8 engine was based on Pontiac’s 389-cid unit, de-stroked to 336 cubic-inches and delivering 200 rated horsepower. Drivetrain choices included a three-speed manual transmission with or without overdrive, a four-speed, and four-speed Hydra-Matic automatic. The standard wheelbase length remained unchanged at 114 inches with a 6 ˝-foot cargo bed, and the optional 123-inch wheelbase included an 8.3-foot cargo bed.

This highly attractive 1959 GMC 100 Stepside Pickup was added to The Museum Collection in early 2010. Prior to acquisition, it was cosmetically restored, the engine was freshened and repainted, and then the pickup was placed into climate-controlled storage by a private collector. Very nicely presented and preserved, it remains visually striking in its two-tone livery, with features including nice brightwork, two-tone upholstery, factory-type polarized sun visors, and period style “Blue Dot” taillights. An extra set of keys is included. Guaranteed to attract admirers wherever it goes, this 1959 GMC 100 Stepside Pickup is highly collectible and enjoyable on all.
