1972 Buick Gran Sport

This 1972 Buick GS 455 is one of a reported 126 convertible examples produced for the model year and was acquired by the selling dealer in April 2023. The car is finished in blue metallic over white vinyl upholstery and is powered by a 455ci V8 paired with a three-speed automatic transmission. Additional equipment includes a power-operated white soft top, 17″ wheels, front disc brakes, power steering, twin hood scoops, quad headlights, power windows, air conditioning, and a push-button AM/FM radio. Work under current ownership involved overhauling the carburetor, servicing the front brakes, and replacing the wheels, tires, master cylinder, water pump, and air conditioning system components. This GS 455 convertible is now offered by the selling dealer with recent service records, a spare set of wheels and tires, rubber floor mats, and a clean Iowa title. The car left the factory finished in Stratomist Blue and is said to have been repainted under prior ownership, and the white soft top was replaced at that time. Details include quadruple headlights, twin hood scoops, painted mirror housings, and chrome trim on the bumpers, rocker panels, and wheel arches. The low-beam headlights, grille emblem, and white top boot were replaced in 2023. US Mags 17″ alloy wheels wear 225/50 front and 255/50 rear Nitto NT555 G2 tires that were installed in June 2023. Braking is from power-assisted front disc and rear drum brakes. Service in 2023 included refinishing the brake booster in addition to replacing the master cylinder, right-rear wheel cylinder, right-front brake caliper, and the front brake hoses, rotors, pads, and wheel bearings. The front and rear bench seats are trimmed in white vinyl and accompanied by color-coordinated door panels and a black dashboard and carpets. Appointments include air conditioning, a push-button AM/FM radio, adjustable front headrests, and convenience lighting. Service in 2023 involved repairing the power windows as well as replacing the dash housing and woodgrain trim, gauge lenses, sunvisor supports, glove box liner, and convertible top switch trim plate. Additional work in 2024 included refinishing the steering column, repairing the center armrest, and replacing the instrument lights, rearview mirror, high-beam switch, and heater core along with the air conditioning compressor and receiver/dryer. The air conditioning system has been converted to utilize R134a refrigerant. The Rallye steering wheel frames a 120-mph speedometer, an analog clock, a fuel-level gauge, and warning lights, while AutoMeter instrumentation mounted below the dashboard consists of readouts for coolant temperature and oil pressure. The five-digit odometer shows 47k miles, approximately 250 of which were added by the selling dealer. Total mileage is unknown. The 455ci V8 was factory rated at 250 horsepower and 375 lb-ft of torque and is equipped with ram-air induction. Work performed since 2023 involved overhauling the carburetor, installing a FlowKooler water pump, and replacing the heater hoses, accessory drive belts, intake manifold gasket, battery and ground cable, battery tray, mufflers, and tailpipes. Power is sent to the rear wheels through a TH400 three-speed automatic transmission and a limited-slip differential.
