1967 Pontiac Bonneville Convertible 428 HO
Overview
This 1967 Pontiac Bonneville Convertible combines elegant styling, sprawling four-passenger appointments, and rare factory-equipped 428 High Output power. Delivered new to Valley Pontiac Company of Youngstown, Ohio, this example is finished in Bamboo Cream over original Black upholstery. Its extensive factory equipment includes a Turbo-Hydramatic automatic transmission, automatic temperature control with air conditioning, Strato front bucket seats, a center console, power-adjustable driver's seat, power windows, Wonder Touch power steering and brakes, Soft Ray tinted glass, push-button radio, stereo tape player, and a remote-controlled driver's side mirror. Professionally restored, factory-correct Pontiac eight-lug wheels complete its distinctive period appearance.
Benefiting from long-term collector upkeep, this Bonneville has undergone extensive mechanical and cosmetic refurbishment while retaining its original 428 HO V8, rebuilt and bored .030-inch over. Additional refurbishment included transmission and differential servicing, frame refinishing, suspension and steering restoration, new body mounts, and replacement of numerous mechanical components. A new radiator, fuel tank, alternator, and convertible-top hydraulics were installed, while reversible upgrades intended to enhance modern drivability include a Demon four-barrel carburetor, electric fuel pump, PerTronix electronic ignition, and LED headlights and taillights. Chrome valve covers are factory equipment, and the original carburetor and fuel pump accompany the sale. Coker Classic radial whitewall tires installed in 2018 have been driven approximately 900 miles. The air conditioning, power-operated convertible top, windows, and driver's seat are reported to function properly, while the car is described as starting easily, running smoothly, and driving without vibrations, hesitation, or fluid leaks.
Most recently serviced in August 2026 with an engine oil change and replacement accessory belt, this Bonneville is accompanied by comprehensive service records and restoration photographs documenting its extensive reconditioning. Additional included items comprise a key set, Pontiac Historical Services reproduction window sticker, factory tool kit, and retained original components. Currently offered by the selling dealer in Fort Myers, Florida, this carefully maintained and thoughtfully upgraded Bonneville Convertible presents a well-equipped example of Pontiac's flagship open-top cruiser.
