Story

1967 Pontiac Grand Prix

The 1967 Grand Prix paired Pontiac's full-size road manners with its most distinctive body of the decade. Concealed headlamps, recessed windshield wipers and long horizontal taillamps separated it from other full-size Pontiacs. It was also the only model year in which Pontiac sold a regular-production Grand Prix convertible.

One page, two bodies

Pontiac identified the hardtop as body 26657 and the convertible as 26667. Factory production records list 37,125 hardtops and 5,856 convertibles, for 42,981 Grand Prix cars in all. Those totals do not reveal how many received a particular engine, transmission, color or option.

The engine choices

The standard Grand Prix engine was its own 350-hp four-barrel 400, calibrated separately for manual and Turbo Hydra-Matic cars. A 265-hp regular-fuel 400 was available with the automatic. Buyers could move up to the 360-hp 428 or the 376-hp Quadra-Power 428 HO. A 428 badge or engine swap does not establish how a particular car was built; Pontiac Historical Services billing records and matching physical identifiers remain the starting point.

Chassis and brakes

The 121-inch-wheelbase chassis used independent front suspension and a four-link, coil-spring live rear axle. A dual-circuit hydraulic brake system was standard for 1967. Front disc brakes, power assist, Safe-T-Track, Rally II wheels and Pontiac's aluminum eight-lug hub-and-drum equipment were optional.

Cabin, paint and top choices

Strato bucket seats and a console were standard. Hardtops could be ordered with cloth-and-Morrokide buckets or a no-cost Strato bench, while convertibles retained expanded-Morrokide buckets. The factory color book documents 15 regular exterior colors plus Coronado Gold, Verdoro Green and Mayfair Maize spring additions, along with body-specific upholstery and top combinations.

Verifying a car

Begin with the VIN and cowl plate, then compare the PHS billing history with engine, carburetor, transmission and axle identifiers and dates. Paint in protected areas, original upholstery evidence, top material and period photographs help separate factory configuration from later restoration choices. Factory-style parts are useful evidence only when the complete record agrees.

Market Observations

  • Auction sale $21,500

    Jun 7, 2026 · Bring a Trailer

    26667 convertible chassis 266677R132100 represented with its factory 400 and Turbo Hydra-Matic automatic · modified · unknown Completed sale at the venue-published winning bid before buyer fees. PHS documentation, a Protect-O-Plate and service records support the represented factory 400, which was rebuilt in 2022, but do not establish every component as born with. A replacement top, prior rear-impact repair, aftermarket audio and alarm equipment, corrosion, dents, inoperative equipment and 79k miles shown remain observation-specific; no locked condition grade is inferred.
  • Auction sale $6,400

    May 11, 2026 · Bring a Trailer

    26657 hardtop chassis 266577E165446 represented with a 400 four-barrel, Turbo Hydra-Matic automatic and Safe-T-Track · survivor · unknown No-reserve completed sale at the venue-published winning bid before buyer fees. PHS documentation and a Protect-O-Plate support the represented factory equipment, while the listing describes a long-stored car requiring service, rust in the trunk and rear wheel wells, cracked tires, interior wear and 14k miles shown. Component-number authentication, total mileage and a locked condition grade remain unknown.
  • Auction sale $32,500

    Apr 4, 2025 · Bring a Trailer

    26657 hardtop chassis 266577C123918 represented with an XY-code 400 and four-speed manual · modified · unknown Completed sale at the venue-published winning bid before buyer fees. PHS documentation and the displayed XY engine stamp support the represented California four-speed configuration, but the car was refurbished, its emissions equipment was removed, and suspension, tires, exhaust and other service parts were replaced. The 89k miles shown, full component originality and locked condition remain unverified, so this record is not merged with automatic hardtops.
  • Auction sale $39,000

    Jul 3, 2024 · Bring a Trailer

    26667 convertible chassis 266677E162594 represented with a 400 and Turbo Hydra-Matic automatic · modified · unknown Completed sale at the venue-published winning bid before buyer fees. PHS documentation accompanied the car, but its black repaint followed body patching and it carried an aftermarket carburetor, ignition, exhaust, wheels, audio and interior work. Rust, a patched floor, a transmission leak, inoperative equipment and 92k TMU miles remain explicit; no component-number authentication or locked condition grade is inferred.
  • High bid $10,750

    Apr 23, 2024 · Bring a Trailer

    26657 hardtop chassis 266577C108030 represented with a 428 four-barrel and three-speed automatic · modified · unknown Reserve-not-met high bid, not a completed sale. The represented 428 automatic hardtop was repainted red from Signet Gold and carried a custom exhaust, nonfactory wheel details and inoperative concealed headlights; removed skirts were included. No PHS billing history, component-number authentication or locked condition grade was represented, and 10k miles shown were TMU, so this remains separate from both 400 hardtop series.
  • Auction sale $15,670

    Aug 13, 2023 · Bring a Trailer

    26667 convertible chassis 266677R114892 represented with a 400 four-barrel and Turbo Hydra-Matic automatic · modified · unknown Completed sale at the venue-published winning bid before buyer fees. The car was repainted in 1980, and the represented 400 was rebuilt in 2000 with a replacement block; replacement exhaust, inoperative climate equipment, worn steering parts, paint flaws, and 30k miles on a rolled odometer make total mileage and component originality unknown. Manufacturer literature accompanied the sale, but no PHS billing history or locked condition grade was represented.

Still Researching

  • production Factory records provide body totals but no trustworthy Grand Prix engine, transmission, paint, trim or option breakdown.
  • rear axle The factory Grand Prix series 266 power-team schedule is normalized by engine, transmission, and air-conditioning application. The rear-axle tooth table also lists 3.55, 3.73, and 4.11 ratios but does not assign them to a Grand Prix power team.
  • option packages The model-specific factory brochure and AMA now support Grand Prix standard equipment, body restrictions, major power teams, and a broad option catalog with selected reported prices, but the complete sales-code, effective-date revision, dependency, and incompatibility schedule was not recovered.
  • authenticity markers Model-level records cannot authenticate an individual car or replace inspection of all drivetrain and date identifiers.
