Its refinished Blue paint highlights the muscular yet understated body lines that defined the GS series. Super Sport wheels provide a classic period-correct look while wrapped in BFGoodrich Radial T/A tires for improved modern grip.

This car was originally produced in Flint, Michigan, the heart of Buick’s manufacturing excellence. The hood features functional scoops that are essential for the Stage 1’s induction system. Consequently, the car possesses a formidable stance that commands respect at any automotive gathering. It successfully maintains the factory aesthetic that made it an icon over fifty years ago.
Refined Interior and Driver-Focused Cabin
The cabin of this 1970 Buick GS Stage 1 offers a striking contrast with its White bench seat interior.

A Hurst shifter rises from the floor, connected to the desirable four-speed manual transmission. The instrument group includes a full set of gauges and a tachometer to monitor the engine’s vital signs. For the driver, a Rally steering wheel provides a tactile connection to the front wheels. Despite its performance nature, the car retains its factory Sonomatic AM/FM radio for a truly authentic user experience. Soft-touch materials and high-quality vinyl ensure that the interior feels as premium as it did in 1970. It is a space designed for long-distance comfort without sacrificing its racing pedigree.
Performance Specifications and Stage 1 Power

In Stage 1 trim, this powerplant was factory rated at an incredible 510 lb-ft of torque, a record for American production cars at the time. This massive output is sent to the rear wheels through a four-speed manual transmission and a factory performance axle. The inclusion of Positraction ensures that the car can effectively put its significant power to the pavement. Every component, from the high-lift camshaft to the specific Stage 1 cylinder heads, works in harmony to provide relentless acceleration. This drivetrain is celebrated for its ability to deliver effortless power across the entire rev range. It offers a visceral mechanical experience that remains unmatched by many modern sports cars. This setup ensures the GS Stage 1 stays competitive with the fastest muscle cars ever built.
