In late 1963, the GTO was developed by John Z. DeLorean as a performance option for the Pontiac Tempest, and it was conceived to give Pontiac some additional performance in their lineup. The GTO combined aggressive styling and even more aggressive performance to lure muscle car buyers to Pontiac. Interestingly enough, the entire project circumvented GM's prohibition of fitting an engine over 330 cubic inches in their intermediate models, making the car somewhat of an in-house hot rod. Nevertheless, it proved to be successful and helped cement DeLorean's reputation in the industry. The GTO option attracted 32,540 buyers in 1964, and according to legend, Pontiac received 5,000 orders before the GM brass even learned of the car's existence.

By 1966, the GTO had been introduced as its own specific model within Pontiac's lineup. Fittingly, it was restyled with a slightly more curvaceous design, and it would gain what would become known as "Coke bottle" styling cues for its rear fender lines. The standard 389-cubic-inch engine was tuned to belt out 335 horsepower, but the most desirable option was the "Tri-Power" setup, which had triple two-barrel carburetors that could bring horsepower to 360, making this high-powered version a fierce competitor on drag strips across America. Many Tri-Power setups were installed by dealers at the customer's request if not already factory installed. 1966 was the last year multiple carburetion was offered on any GM car with the exception of the Corvette, bringing an end to an era at GM. The 1966 GTO has been at the top of the list of many collectors for this reason and for the 1966 GTO's sleek body design that makes these look like they are going fast even when standing still.

According to the car's PHS (Pontiac Historical Services) documents that accompany the car, when this 1966 Pontiac GTO convertible was delivered new, it was equipped with a four-barrel 389 that was mated to an automatic transmission, 3:23 Safe-T-Track rear axle, power steering, power brakes, rally clock, optional console with vacuum gauge and air-conditioning. It wore Montero Red paint with a black interior, which is the same color combination it sports today. The 1966 GTO is a fantastic car, but this Pontiac has been tastefully enhanced in just the right areas to make owning and driving this muscle car classic even more enjoyable. At the top of the list is the addition of Pontiac's legendary Tri-Power triple two-barrel carburetion system. There is nothing quite like the feel and sound of a Pontiac 389 when the three Rochester two-barrels are activated, creating a mechanical symphony of sound that defines why so many enthusiasts love the Pontiac GTO. Other welcomed upgrades are a TH350 automatic transmission as well as an aluminum radiator to keep things cool. The thoughtful pairing of the Tri-Power and the three-speed transmission significantly adds to this classic GTO's performance and drivability. The correct Montero Red paint is deep and glossy, contrasting beautifully with the black bucket seat interior and power-operated convertible top. Adding to this Pontiac's handsome good looks are a set of highly desirable Pontiac Rally One wheels wrapped with Redline radial tires that capture the classic muscle car look, but with the ride, safety and handling characteristics that modern radial tires provide.

The GTO Convertible proved to be a massive success for Pontiac, with a total of 96,946 examples sold, and the 1966 model remains one of the most beloved by enthusiasts. This example checks all the right boxes. With a great color scheme, a desirable list of factory options, an upgraded automatic transmission, a Tri-Power 389 with PHS documents, this clean, well-kept and stylish early Pontiac muscle car is ready to be enjoyed.
