Four-Speed: 1977 Pontiac Grand Prix – SOLD!
November 22nd Update – The unique four-speed manual conversion in this final-year, 400-powered Pontiac Grand Prix is likely the key reason this car did not take long to sell. With the Craigslist listing deleted by the seller, we’re calling this one “Sold!” While this one got away, please reach out either by email or call Rudy directly if you’d like to be informed when we come across something similar.
1977 proved to be the final year of GM’s mid-sized Colonnade Hardtop personal luxury coupes as the company readied its downsized versions for the next model year. Pontiac’s version, the Grand Prix, also featured the division’s 400 cubic inch V8 for the last time. This driver-quality example we discovered first listed in November 2020 on Craigslist in Southington, Connecticut features a unique four-speed manual transmission conversion and an asking price of $5,000. Researching the Collector Car Market Review Online Tool reveals the private seller has their Grand Prix priced between this guide’s #4 “Fair” estimate of $3,750 and its #3 “Good” appraisal of $7,450. Similarly, the Hagerty Insurance Online Valuation Tool as a second data point confirms this private seller has his Model SJ Ford priced between the #4 “Fair” (Daily Driver) appraisal of $4,200 and the #3 “Good” estimate of $6,900.
For model year 1973, Pontiac launched the third generation of its popular personal luxury coupe, the Grand Prix, on the new A-Body “Colonnade” hardtop platform shared with the Chevrolet Monte Carlo, Oldsmobile Cutlass Supreme, and Buick Regal. With more emissions and safety features being added throughout the mid-70s, Pontiac increasingly focused on the luxury aspect of these cars as power output declined with each succeeding year. About the only styling cue differentiating second-generation Grand Prixs from their A-Body siblings was the cockpit-style wrap-around dashboard continued from the second-generation car. The 1977 example presented here is the last of the “big” Grand Prixs before GM downsized the A-Body line for 1978. The long hood, short deck design initiated on the second generation Grand Prix looks even better on these later models.
We found this vintage “Pontiac: The Mark of Great Cars” commercial featuring a 1977 Grand Prix on YouTube:
In addition to the four-speed conversion, we like the documentation and overall driver-quality condition that belies this Grand Prix’s mileage. The first project we would tackle is having a professional replace the landau vinyl top as it does detract from the overall condition of the car based on the pictures provided. Good luck with the purchase!
