Despite the fourth-generation Bonneville launching in 1965, the 1967 model year still brought an important styling update, with a new grille design and substantial refinements in the cabin.Pontiac also focused on the engine lineup to boost the car’s performance appetite, dropping some V8s and introducing new ones with increased power.
For example, the carmaker retired the 389 specifically to make room for an all-new 400 (6.6-liter) developing 333 horsepower – the same engine was further upgraded a year later to generate 340 horsepower. The 421 waved goodbye to the Bonneville, too, this time to pave the way for a 428 (7.0-liter) unit rated at 360 horsepower.
Most Bonnevilles rolling out in 1967 used a 4-door body style, with only 30% of the car leaving the factory as a 2-door hardtop.One of these rare hardtops is now looking for a new home in a condition you don’t see often. The car is a genuine survivor, so the single family that owned it since new never started a restoration, rebuilt the engine, or replaced body panels. The Bonneville is as original as it gets, though it did require (and receive) some essential fixes, such as a new exhaust system.
The vehicle sells with all service and maintenance records since new, and the owner promises they always parked the car in a garage. It looks impressive, though you’ll still find some surface rust in the trunk and on the undersides and some occasional paint bubbling. Such issues are normal on a car this old, mainly because it has never been restored. The owner says they never did any type of bodywork or replacement of panels, and the original paint has remained untouched all these years.
The engine in charge of propelling this Bonneville is the 400 I told you about earlier. It produces 333 horsepower and comes with the original Carter AFB 4-barrel carburetor. Everything works correctly, so if you want to use this Bonneville as a daily driver, the vehicle is fully prepared to do this. The hardtop has just 65,900 miles (approximately 106,000 km) on the clock, and considering it has never been molested, they are all original.
