The 1967 Buick GS 400 represents a pivotal moment in the muscle car era when Flint moved away from the Nailhead engine. This specific example, crossing the block at Glendale 2026, has undergone a comprehensive frame-off restoration to factory specifications. It serves as a high-water mark for the brand’s performance division during the late sixties. Collectors often overlook these models in favor of the Chevelle, yet the Buick offers a level of sophistication those rivals frequently lacked.
Visual Refinement and Stance
The exterior of this Gran Sport is finished in factory-correct Mist Blue, a shade that highlights the sweeping coke-bottle contours of the A-body platform. A crisp black vinyl top provides a sharp contrast, while the iconic twin hood scoops signal the functional performance capabilities of the machine. Chrome and trim pieces have been meticulously restored or replaced to ensure a mirror-like finish across the bumpers and brightwork. Red bodyline sport striping and matching GS emblems add a subtle aggressive touch to the otherwise elegant silhouette.
Cabin Sophistication and Technology
Inside the cabin, the Light Fawn interior offers a luxurious departure from the standard black vinyl found in most performance cars of the period. This 1967 Buick GS 400 features bucket seats and a center console equipped with an optional console-mounted tachometer for precise monitoring. While the dashboard retains its pushbutton radio and factory clock, a modern aftermarket stereo has been cleverly hidden to preserve the vintage aesthetic. Factory air conditioning remains a standout feature, providing modern comfort within a strictly period-correct environment.
Powertrain and Mechanical Feedback
The heart of this vehicle is its matching numbers 400 cubic inch V-8 engine, which utilized the new-for-1967 thin-wall casting design. This powerplant produces 340 hp/PS and 440 lb-ft/Nm of torque, delivered through a four-barrel carburetor topped with the rare “Star Wars” air cleaner. Power is managed by a Super Turbine 400 automatic transmission, known for its durability and smooth shifts under heavy acceleration. The dual exhaust system provides a deep, rhythmic note that defines the era of big-block American displacement.

Competitive Landscape and Rivals
During its original production run, the 1967 Buick GS 400 competed directly with the Pontiac GTO and the Oldsmobile 442. While the GTO captured the youth market, the Buick was positioned as the “gentleman’s muscle car,” offering higher build quality and more standard features. Its unique selling point remains the balance of massive torque and premium amenities like power steering and four-wheel disc brakes. Today, the Buick is considered a more exclusive alternative to the common Chevrolet SS models found at most regional auctions.
Valuation and Investment Potential
With roughly 13,000 hardtops produced for the 1967 model year, finding an example that retains its original VIN and cowl data tags is increasingly difficult. The inclusion of the Star Wars air cleaner alone adds significant value to this lot, as these components are highly sought after by Buick purists. Restoration costs for these vehicles often exceed their market value, making a pre-restored, numbers-matching car a financially sound acquisition. As the market shifts toward verified survivors and high-quality restorations, this GS 400 is positioned for long-term appreciation.
This 1967 Buick GS 400 represents a rare opportunity to own a fully documented, frame-off restored piece of GM history. Its blend of factory air conditioning, matching numbers drivetrain, and striking color combination makes it a premier candidate for any serious American muscle collection.
