1975 Buick LeSabre Custom Convertible

This 1975 Buick LeSabre Custom convertible was acquired by the current owner in 2024 and is powered by a 350ci V8 mated to a three-speed automatic transmission. Factory-finished in Glacier Blue, the car has a power-operated white convertible top along with 15″ Rallye wheels, front disc brakes, white vinyl upholstery, and air conditioning. This final-year LeSabre convertible shows 91k miles and is now offered by the seller on behalf of the owner with period literature, recent service records, and a Texas title.

The car was factory-finished in Glacier Blue and has been repainted. It is equipped with a power-operated white soft top along with fender VentiPorts, swept bodyside sculpting, and quad headlights. The convertible top was adjusted and the cables were replaced in 2025. Corrosion is visible in the trunk drip channels.

The 15″ Rallye wheels are mounted with Milestar narrow-whitewall tires measuring 225/75. The car is equipped with power steering, and the power-assisted brakes utilize front discs and rear drums. Helper springs are fitted on the rear shocks, and pitting is visible on the wheels.

The seats are upholstered in white vinyl and complemented by a blue dashboard, carpeting, and door panels. Interior appointments include air conditioning, an inoperative push-button AM/FM radio, woodgrain trim, and a clock. The carpet, padding, front seat bottoms, door panels, and kick panels were replaced in 2024, and the air conditioning was recharged with R12 in 2025. Circular marks are visible in the front center armrest.

The two-spoke steering wheel fronts a horizontal 100-mph speedometer, a fuel-level gauge, and a gear indicator. The five-digit odometer shows 91k miles, approximately 900 of which were added under current ownership.

The 350ci V8 was factory-equipped with a four-barrel carburetor and was rated at 165 net horsepower when new. The spark plugs were replaced in 2024 and the battery was replaced in August 2026.

Power is routed to the rear wheels through a three-speed automatic transmission. There is a leak at the differential housing.
