The 1972 Buick GS 455 Stage 1 Coupe holds a distinct place among the performance cars of its era. Unlike some competitors, the GS combined brutal V8 power with Cadillac-level interior refinement. This particular car underwent a comprehensive refurbishment around 2001, ensuring its powerful presence remains strong. Importantly, the Stage 1 designation indicates a rare and desirable factory performance package. The Bronze exterior paired with a black vinyl roof creates a uniquely sophisticated muscle machine.
Design and Exterior Appointments
The body is finished in a period-correct Bronze, beautifully complemented by the contrast of a black vinyl roof cover. This color combination emphasizes the car’s aggressive lines and classic hardtop silhouette. Gran Sport badging is found prominently on the exterior, signifying its high-performance pedigree. The car also features a functional ram air hood, essential for feeding air to the massive engine. The chrome rear bumper includes factory integrated exhaust finishers, a clean design touch. The seller notes that the front bumper has been replaced during its history.

Handling and Suspension Components
To manage the significant torque produced by the 455 V8, the chassis benefits from key suspension components. The car is equipped with power steering, making the large coupe easy to maneuver. Furthermore, Bilstein shocks have been installed, providing better damping and control. The addition of front and rear sway bars works to reduce body roll during spirited driving. Braking is handled by power-assisted front discs and rear drums, an effective setup for the time.

Wheels and Tire Condition
This GS Stage 1 rides on the correct 15-inch Rallye wheels. These iconic wheels are instantly recognizable and perfectly suit the car’s aesthetic. They are currently mounted with older BFGoodrich Radial T/A tires. It is important to note that these tires require replacement due to age, not tread wear. A full-size spare tire is properly stowed and ready for use in the trunk.
Interior Luxury and Amenities
The cabin is outfitted for comfort, consistent with Buick’s luxury-muscle philosophy. The front bucket and rear bench seats are upholstered in Tan vinyl, joined by matching door panels. Woodgrain trim accents the interior, adding a touch of class to the muscle car environment. Modern conveniences include factory air conditioning, power windows, and power locks. The air conditioning system still blows cold air, though a minor leak is noted at the compressor pulley.

Driver’s Control and Instrumentation
The driver interacts with a three-spoke Rallye steering wheel mounted to a tilting column. The instrument cluster includes a 120-mph speedometer, an 8k-rpm tachometer, and a combination gauge. The odometer currently indicates 99,000 miles, with approximately 300 miles added by the current owner. The Sonomatic AM radio remains in the center console. Notably, the cruise control system is currently non-functional and requires attention.

Power, Engine Specs, and Performance
Under the ram air hood is the massive 455 cubic inch V8 engine. This engine was factory rated at net 270 horsepower and 390 lb-ft of torque. The engine underwent an overhaul around 2001 and was fitted with a performance Casper camshaft. It is further upgraded with an Edelbrock intake manifold and a Holley carburetor. Spark is provided by a Mallory distributor, and cooling by a Harrison radiator. Power is routed through a three-speed TH400 automatic transmission. The robust torque is delivered to the rear wheels via a limited-slip differential. A dual exhaust system with Dynomax mufflers completes the performance package.

Summary of the GS Stage 1 Coupe
This 1972 Buick GS 455 Stage 1 Coupe is a powerful blend of classic muscle car performance and Buick comfort. The rebuilt 455ci V8, paired with a TH400 automatic transmission, provides immense, usable torque. Its rare Stage 1 status, power accessories, and eye-catching Bronze finish make it highly desirable. This GS stands as a well-preserved example of one of the last true big-block luxury muscle cars.
