The 1965 Buick Riviera GS represents a high-water mark for American personal luxury cars. While many 1960s icons relied on brute force alone, the Riviera combined sophisticated styling with a refined chassis. This particular example, Lot V390, showcases the rare Gran Sport package that transformed a stylish cruiser into a legitimate performance threat. Its Flame Red exterior and hidden headlights create a presence that remains unmatched by its contemporary rivals. Finding a matching numbers car in this condition is a significant opportunity for any serious collector today.
The Heart of the Nailhead Engine
Under the hood lies the legendary 425 CI Nailhead V-8 engine. This powerplant earned its nickname from the unusually small, vertically mounted valves that resemble nails. Despite the quirky design, the engine produces a massive 360 HP and 465 lb-ft of torque. The Gran Sport package specifically included the “Super Wildcat” setup, which utilized dual Carter four-barrel carburetors for improved breathing. This engine remains the original, matching numbers unit, which is a critical detail for maintaining the vehicle’s long-term market value.
Mechanical Upgrades and Transmission
Power is sent to the rear wheels via a Turbo 400 three-speed automatic transmission. This gearbox was widely regarded as one of the best in the world during the mid-1960s for its smoothness. The GS package also brought a numerically higher rear axle ratio for better off-the-line acceleration. Additionally, the car features a heavy-duty suspension system that helps manage the weight of the luxury coupe during spirited driving. These mechanical enhancements ensured the Riviera lived up to its Gran Sport badges on the open road.
Exquisite Styling and Clamshell Lighting
The 1965 model year is famous among enthusiasts for being the only year to feature the vertically stacked hidden headlights. These lights are tucked behind electrically operated clamshell doors, giving the front end a clean and aggressive look. This car is finished in Code 624 Flame Red, a bold choice that highlights the sharp creases of the Bill Mitchell design. The restoration, completed in 2017, has preserved these unique styling cues while ensuring the bodywork remains laser-straight and period-correct.
Luxury Interior and Power Features
Step inside and you are greeted by a striking White vinyl interior that provides a sharp contrast to the red paint. The cabin is loaded with premium options including power windows, a power antenna, and a factory AM/FM radio. Driving comfort is enhanced by power steering and power brakes, making this muscle car surprisingly easy to navigate through modern traffic. Even the trunk release is power-operated, highlighting Buick’s commitment to providing a top-tier luxury experience for its most discerning 1960s clientele.
Performance Specifications and Drivetrain
This 1965 Buick Riviera GS is powered by its original 425/360 HP Nailhead V-8 engine equipped with dual-quad carburetors. It generates 465 lb-ft of torque at a low 2,800 RPM, allowing for effortless high-speed cruising. The drivetrain consists of a Turbo 400 automatic transmission and a factory-spec rear end. Additional highlights include 4-wheel power brakes and the correct factory wheels, all maintained following a comprehensive restoration finished in 2017.
Summary of the Riviera Gran Sport
The 1965 Buick Riviera GS is a masterpiece of automotive design and engineering. As one of the few years that perfectly balanced the sleek E-body lines with high-output V-8 power, it remains a favorite at any high-end auction. This matching numbers example offers a rare combination of original mechanicals and a high-quality restoration. For the enthusiast seeking a mix of muscle car performance and Cadillac-level luxury, this Flame Red beauty is a standout choice. It will certainly be a focal point when it crosses the block this March.
