The 1966 Pontiac Bonneville Convertible remains a peak example of mid-sixties American luxury and wide-track performance. Dressed in Code L Marina Turquoise, this full-sized cruiser represents a rare mechanical combination for the era. Most luxury drop-tops from this period were equipped with automatic transmissions for effortless boulevard driving. However, this specific model features a factory four-speed manual transmission, offering a more engaging experience. The car displays 67,035 miles on the odometer and maintains a high level of originality. It is scheduled to cross the block at the Kissimmee 2026 auction on Saturday, January 10th. Enthusiasts will appreciate the extensive documentation included, such as the PHS papers and original window sticker. It serves as a vibrant reminder of when Pontiac dominated the premium performance market.
Marina Turquoise Aesthetics and Interior Preservation
The exterior of this 1966 Pontiac Bonneville Convertible is finished in its striking original shade of Marina Turquoise. This color is perfectly complemented by a new power-operated convertible top that includes a glass rear window. Inside, the cabin retains its original Marina Turquoise leather upholstery, showcasing the brand’s premium 1960s craftsmanship. While the carpet has been replaced to freshen the appearance, the rest of the interior feels authentic. An original Delco AM radio sits in the dashboard, maintaining the vintage atmosphere of the cockpit. Furthermore, the expansive seats and woodgrain accents highlight the upscale nature of the Bonneville trim level. This interior was designed for comfort during long-distance coastal tours with the top down. Consequently, the car feels like a time capsule from the height of the jet-age design.
Chassis Features and Original Factory Accessories
Maneuvering this large-bodied 1966 Pontiac Bonneville Convertible is made much easier by the inclusion of power steering. The car sits on a chassis that was famous for its “Wide-Track” stance, providing superior road stability. To ensure authenticity, the vehicle comes equipped with its original spare tire and jack in the trunk. The dual exhaust system provides a subtle but muscular tone that fits the character of a high-end Pontiac. Underneath, the car remains well-sorted, reflecting the care indicated by its relatively modest mileage. Every trim piece and emblem contributes to the imposing street presence that these cars commanded when new. These factory-correct details are essential for collectors who value historical accuracy in their vehicles. It is a well-rounded machine that balances massive visual scale with delicate styling touches.
Four Speed Manual Logic and PHS Documentation
Finding a full-sized 1966 Pontiac Bonneville Convertible with a manual gearbox is an increasingly difficult task today. The PHS documentation confirms that this car left the factory with the four-speed floor shifter intact. This option transformed the Bonneville from a standard luxury cruiser into a legitimate driver’s car. It allows the pilot to fully utilize the power band of the 389 V-8 engine. Most buyers in 1966 opted for the Hydra-Matic, making this manual version a standout for rarity. The inclusion of the original window sticker adds a layer of provenance that is highly prized. Such documentation proves the car’s history and original specifications for the discerning bidder. This history is vital for maintaining the long-term value of such a significant American convertible.
Technical Engine Specs and Wide Track Performance
This 1966 Pontiac Bonneville Convertible is powered by a 389 cubic inch V-8 engine delivering classic big-block torque. The factory 4-speed manual transmission sends power to the rear wheels, providing a rare level of mechanical control. Dual exhaust allows the engine to breathe freely while producing a signature Pontiac rumble under acceleration. Power steering assists the driver in managing the substantial weight and length of this premium convertible. The braking system remains correct to the period, offering steady stopping power for weekend cruising. With 67,035 miles, the drivetrain has been exercised enough to remain healthy without being worn out. These specifications define a car built for high-speed highway travel and impressive boulevard presence. It is a technical masterpiece of 1960s GM engineering that still performs admirably today.
Summary of a Marina Turquoise Survivor
The 1966 Pontiac Bonneville Convertible stands as a definitive pillar of the brand’s golden era of styling.
