This 1963 Buick Riviera is powered by a 401ci Nailhead V8 that is topped by an Edelbrock carburetor and backed by a 4L60E four-speed automatic transmission, which was installed in 2020. Additional work involved fitting a transmission controller and cooler, a replacement exhaust, and rebuilding the driveshaft. The car rides on lowered suspension and US Mags wheels over four-wheel disc brakes, and it also has a replacement exhaust system, a performance power steering box, anti-sway bars, and a limited-slip differential. Inside, black upholstery covers the bucket seats, and other details include Dakota Digital instrumentation, woodgrain trim, cruise control, and an aftermarket sound system with a retro-look head unit, an amplifier, and a subwoofer. Acquired by the seller in 2022, this Riviera is now offered at no reserve with service records and a clean Minnesota title in the seller’s name.
Finished from the factory in Arctic White, the car is equipped with LED headlights, a remote-controlled driver-side mirror, faux quarter panel scoops, chrome bumpers, and dual exhaust outlets. Various light sockets and switches were repaired or replaced in 2020. The windshield and rear window are replacements.
Suspension incorporates lowering springs, Bilstein shocks, anti-sway bars, and urethane track bar bushings. A performance steering box was installed in 2020. The car rides on 17″ US Mags wheels over four-wheel cross-drilled and slotted discs, and the braking system has a replacement booster, master cylinder, and lines as well as an emergency brake.
The front and rear bucket seats are trimmed in black upholstery, and woodgrain trim accents the center console and door panels. The driver’s seat is power adjustable, and cruise control was added in 2024. The sound system features a retro-look Bluetooth head unit, aftermarket speakers, a subwoofer, and an amplifier. The air conditioning does not work.
The woodgrain-rimmed steering wheel is mounted to a tilting column and frames Dakota Digital instrumentation. The odometer shows under 4,500 miles, approximately 4k of which were added under current ownership. Total mileage is unknown.
The 401ci Nailhead V8 is topped with an Edelbrock 800-CFM carburetor, which is fitted with a throttle position sensor kit. The idle was adjusted in 2025, and the fuel filter was replaced. Additional work since 2020 has involved replacing the radiator, upper radiator hose, and exhaust as well as installing a mini starter and modifying the intake manifold. The engine is backed by a 4L60E four-speed automatic transmission, which was installed in 2020 and equipped with a transmission cooler and a Painless Performance Perfect Torc transmission controller. The driveshaft was also rebuilt in 2020. The limited-slip differential was serviced in 2024, and the transmission mount was replaced. The seller reports a noise when letting off the gas.
