The 1966 model year solidified the GTO’s standing as a muscle car titan. This year saw the GTO become a standalone model, rewarding Pontiac with its highest annual sales figures. This magnificent, concours-restored 1966 Pontiac GTO Hardtop represents the best of that era. It blends powerful performance with an impressive suite of optional comfort features. Finished in the rare Tiger Gold poly, it possesses striking visual appeal. This car’s exceptional condition is matched by its fascinating history and documentation.
Rare Color and Immaculate Restoration
The GTO received its famous “Coke bottle” body design in 1966. This sculpting gave the car a more muscular and aggressive stance than before. The sheet metal sweeps dramatically over the wheel arches. This particular example is finished in the stunning Tiger Gold poly color. That paint choice was part of a special marketing push linked to the famous “Tiger” theme. The car is further enhanced by a black vinyl roof. Correct original red wheel liners are fitted at the front and rear.

Concours Detailing and Provenance
This 1966 Pontiac GTO underwent a professional concours restoration. This process ensures the car presents in factory-correct, show-ready condition. The sale is supported by its original Protect-O-Plate and window sticker. Furthermore, it comes with extensive PHS (Pontiac History Services) documents. It was previously part of the prestigious Jim Mattison collection. This provenance confirms its authenticity and high regard within the hobby. It is purported to be a special order for a dealership showroom display.
A Highly Optioned and Luxurious Interior
The interior features black upholstery over bucket seats and a console. These seats also include optional headrests for added safety and comfort. For 1966, the dash received a revised look. It integrated Rally gauges, including a factory tachometer, directly in front of the driver. The instrument panel gave the GTO a decidedly performance-oriented cockpit feel. This GTO further features the highly desirable factory air conditioning.

Comfort and Convenience Equipment
Luxury and convenience options make this GTO a superb machine. The interior is equipped with Soft Ray glass to reduce glare and heat. It also includes the interior lamp package for better visibility at night. A rear defroster was optioned, improving winter functionality. The driver benefits from a tilt steering column. This column is topped by a sporty three-spoke wheel. The entertainment system includes an AM/FM radio with the unique Verba-Phonic feature.
Tri-Power Engine and Performance Heart
At the core of this hardtop resides the matching-numbers 389 cubic-inch V8 engine. This engine is equipped with the renowned Tri-Power setup. This means it uses three two-barrel carburetors, yielding 360 horsepower. It was a potent engine and a highly sought-after option. The engine also features the optional transistorized ignition system. This system delivered a hotter spark and improved reliability. This engine combination defined muscle car power for the era.

Power and Drivetrain Specifications
The 389/360 HP V8 generates 424 lb-ft of torque. That ample power is controlled by a close-ratio 4-speed manual transmission. The engine setup featured a high 10.75:1 compression ratio. This provided rapid acceleration on demand. This powertrain combination offers an incredibly visceral driving engagement. The driver is fully involved in maximizing the performance of the 1966 Pontiac GTO. Standard equipment like power steering and power brakes further aids control.

A Benchmark of the Muscle Car Era
The 1966 GTO represents the peak of Pontiac’s dominance in the muscle car market. This specific hardtop exemplifies the best of that year’s production. It features the powerful 389 Tri-Power V8 and 4-speed manual. The rare Tiger Gold color and full documentation only increase its desirability. This 1966 Pontiac GTO is truly a museum-quality piece. It stands ready to be appreciated by its next knowledgeable owner.
