Description/extras: Owner's manual. The 1969 Buick GS 400 Stage 1 Convertible is one of its era's most revered muscle cars. With its powerful 400 cubic-inch (6.6L) V8, upgraded four-speed automatic transmission with overdrive, and limited-slip differential, this car delivers both raw power and refined cruising capability. Finished in Cherry Red over a Pearl White vinyl interior, this meticulously restored classic represents a rare opportunity for collectors and enthusiasts alike.
Initially rolling off the assembly line in Flint, Michigan, as confirmed by the “H” code in the VIN, this GS 400 was initially sold in Canada. Its authenticity is further validated by the 46 in the VIN, which designates it as a genuine GS 400. The car comes with GM of Canada documentation, making it a particularly desirable example for those who value provenance and originality.
While it originally wore a Code-69 Silver Mist exterior, the body has been professionally refinished in Cherry Red, giving it a striking, high-gloss finish. The repaint was executed excellently, with no visible rust or imperfections. The stock black power convertible top was replaced with a white one featuring a glass rear window, enhancing the car’s aesthetics and usability.
The Pearl White vinyl bucket seat interior (Code-185) has been wholly reupholstered, restoring it to showroom condition. The bucket seats provide a comfortable yet sporty driving experience. The centre console has a new shifter plate that correctly displays the gear positions for the upgraded overdrive transmission. This subtle but important detail showcases the attention to originality in this car’s restoration.
The GS 400 Stage 1 was known for blending muscle car performance with luxury; this example stays true to that reputation. Power windows, an extra-cost feature at the time, add convenience to the classic interior. The GM of Canada documentation also confirms the presence of tinted windows, an AM radio, and rear speakers, making it a well-equipped car for its era.
A VDO tachometer complements the factory gauges on the steering column. Below the dashboard, accessory gauges provide additional real-time performance readings. Meanwhile, an aftermarket stereo system cleverly conceals itself in an 8-track tape player housing, preserving the classic look while offering modern audio capabilities.
Under the hood, this GS 400 houses a 400 cubic-inch V8 engine that produces 345 horsepower and 440 lb-ft of torque. The factory Stage 1 package added additional performance enhancements, including larger valves, a high-performance camshaft, and optimized ignition timing, ensuring this Buick delivered impressive straight-line speed.
To enhance drivability, a 200-4R four-speed automatic transmission with overdrive has been installed, replacing the original Turbo 400. This upgrade allows for more comfortable highway cruising while retaining the raw acceleration that car enthusiasts crave. The shifter plate was updated accordingly, reflecting this modern enhancement.
A limited-slip differential with 3.73:1 gears and an aluminium cover ensures maximum traction during spirited driving. This setup balances acceleration and highway usability, making this GS 400 a joy to drive in various conditions.
The dual exhaust system, featuring a crossover pipe, improves performance and enhances the signature V8 soundtrack. Meanwhile, a brand-new fuel tank has been installed, ensuring reliable fuel delivery and long-term dependability.
Every suspension system component has been rebuilt, giving this GS 400 an as-new driving feel. Additionally, a rear anti-roll bar was added to improve handling and enhance stability during cornering without compromising ride comfort.
Rolling on extra-cost chrome-plated wheels wrapped in 14-inch BFGoodrich Radial T/A tires, this Buick maintains a period-correct muscle car stance while benefiting from modern tire performance. The factory Rallye wheel is also included, adding to the car’s authenticity and collectibility.
A combination of power steering and power drum brakes brings this classic muscle car to life, making for an easy and enjoyable driving experience. Whether navigating city streets or open highways, this GS 400 offers the balance of muscle and refinement that Buick was known for in the golden age of American performance cars.
The sale includes GM of Canada documentation, a Buick Master Parts Catalog, Buick manuals, a GS Quick Reference Guide, a copy of the order form, and a reproduction window sticker. These documents provide invaluable historical insight, further cementing the car’s authenticity and desirability.
This GS 400 Stage 1 has been owned and cherished for the past 25 years. Its restoration was carefully executed to preserve originality and usability. The extensive documentation and long-term ownership history make it a standout example among its peers.
For enthusiasts and collectors seeking a highly restored, fully documented classic muscle car, this 1969 Buick GS 400 Stage 1 Convertible is a prime candidate. Combining rarity, performance, and luxury, it represents one of the finest muscle cars of its era.
