Having caught the automotive community by storm, the Pontiac GTO introduced in 1964 would eventually come to be credited as the first American muscle car and an icon that helped define a generation. Throughout the late 1960s, however, the performance bar was continually raised higher as competition increased in the pony and muscle car markets. The editors at Car and Driver commented, "If Oldsmobile, Buick and Chevrolet were going to have engines over 450 cubes in their A-Body cars, then the GTO had to have one, too.” Pontiac’s answer was a 455 cubic inch V8 to complement their already popular Ram Air III and Ram Air IV engines. Producing 360 horsepower and an astonishing 500 pound feet of torque, a GTO equipped with a 455 was capable of running the quarter mile in less than 15 seconds. In addition, the GTO benefited from minor cosmetic and technical changes such as four exposed headlamps, a stiffer suspension, and optional power steering, which significantly improved the car’s handling.

The 1970 Pontiac GTO Convertible offered here features the aforementioned 455 cubic inch V8 but is particularly rare in that it has an automatic transmission, as evidenced by the build sheet. Of the roughly 40,000 GTOs sold in 1970, only 3,615 were convertibles, of which even fewer examples had a 455 coupled to an automatic transmission. This red GTO was purchased by John McMullen with very low mileage in 1995, having previously undergone a full body-off restoration. The restoration itself was well done, with the paint remaining today in very good condition, polished to a smooth appearance, showing only minor imperfections upon close examination. The same can be said for the bodywork, panel fitting, and stainless and chrome trim, all of which are well within acceptable limits. However, due to visible scrapes and minor imperfections, this car would benefit from having all four pieces of side glass replaced, in order to bring it closer to concours quality.

The interior of this GTO seems equally as well restored, as the saddle colored upholstery, carpets, and side panels all appear to be in “as new” condition. The instrumentation is crisp and clear and is accented by wood grain free of any visible imperfections. As for the engine bay and block, every component is nicely refinished with the proper corresponding hoses, decals, and markings.

Most importantly, however, the GTO presented here benefits from numerous options and Trans Am extras adding not only to its rarity but also its value in the eyes of Pontiac enthusiasts. In addition to being a convertible outfitted with a high output V8, it has power steering, power brakes, Rally II wheels with a matching spare wheel and tire in the trunk, buckets seats, a tilt steering wheel, an 8-track cassette player, as well as a remote driver’s side mirror. Finally, the optional hood-mounted tachometer adds to the already aggressive Rally gauge package on the interior.

Few muscle cars can hold their own in the presence of a Chevrolet Chevelle SS or a Plymouth Road Runner. This Pontiac Trans Am GTO Convertible, however, is precisely such a car. Equipped with a torquey 455 cubic inch V8, mated to an automatic transmission, this GTO represents the pinnacle of powerful American muscle restored to be driven and enjoyed.
