The Grand Prix was a line of automobiles produced by the Pontiac Division of General Motors from 1962 through 2002 for coupes and 1988–2008 for sedans. First introduced as part of Pontiac's full-size car model offering for the 1962 model year, the marque varied repeatedly in size, luxury, and performance during its lifespan. Among the changes were positioning in the personal luxury car market segment and mid-size car offering from the 2nd generation to the 5th generation for the sedan and from the 2nd generation to the 6th generation from the coupe; it returned to a full-size car from the 6th generation to the 7th generation for the sedan, positioned below the larger Bonneville in Pontiac's model lineup.
The Grand Prix first appeared in the Pontiac line for the 1962 model year, as a performance-oriented replacement for the Ventura, which became a luxury trim level of the full-size Catalina It was essentially a standard Catalina coupe with minimal outside chrome trim and a sportier interior (bucket seats and a center console). The performance-minded John De Lorean, head of Advanced Engineering at Pontiac, contributed to the development of both the Grand Prix and the GTO. Early models were available with Pontiac performance options, including the factory-race Super Duty 421 powertrain installed in a handful of 1962 and 1963 cars.
The full-size Catalina-based Grand Prix sold well through the 1960s.
Revised sheetmetal with rounded but even more pronounced Coke bottle styling highlighted the 1967 Grand Prix and other full-sized Pontiacs. A convertible was new, which lasted only the 1967 model year. Also new to the GP were concealed headlights with horizontal mounting (all other full-size '67 Pontiacs retained the vertical headlights for one more year), concealed windshield wipers and ventless front windows on hardtop coupes. Out back were louvered taillights similar to those found on the GTO.
Inside, Strato bucket seats and console were still standard equipment with Morrokide vinyl or cloth upholstery, or a no-cost optional notchback bench seat with either trims. Other changes included a revised instrument panel and door panel trim. Under the hood, the 389 V8 was replaced by a new 400 cu in V8 with four-barrel carburetor, dual exhausts and 350 hp. Similarly, the 421 V8 was replaced by a new 428 cu in V8 rated at 360 hp or an HO version with 376 hp - both with four-barrel carburetors. Both the 400 and 428 V8s were basically bored out versions of the older 389/421 block but with various internal improvements including bigger valves and improved breathing capabilities.
New this year was a dual master-cylinder braking system and optional front disc brakes along with Rally II wheels. Also new for 1967 was an energy-absorbing collapsible steering column. Plus, Pontiac added an 8-track Stereo tape player.
This very nice example is one of just 5,856 Convertibles produced in this-the only year for Grand Prix Convertible production. Finished in Signet Gold Metallic with a Black top and Black Interior, the car sports the Strato Bucket Seats with Console, A/C, Tilt Wheel, PS, PB, Power Top with Glass Rear Window, and the 8 Lug Wheels. This low mileage example has been collector owned for many years and is a veteran of AACA tours in the Cincinnati Area. The car runs and drives without fault, and really needs nothing to be pressed into immediate service. These 67 Grand Prix Convertibles have really developed a bit of a cult following and are a sure bet for increased value as the hobby continues to show appreciation for Luxury cars from the 60’s.
