This 1977 Cadillac Eldorado Coupe is said to have been registered with one owner for nearly 50 years, and it shows 26k miles. The car is finished in Frost Orange Firemist over Antique Saffron Sierra Grain leather, and it features a Dual Comfort front bench, a power-adjustable driver’s seat, a power trunk release, automatic climate control, and an AM/FM stereo with an eight-track player. The vehicle was acquired out of Michigan by its current owner in 2025, and subsequent work included servicing its 7.0-liter V8, three-speed automatic transmission, hydro-boost disc brakes, headlights, tires, air conditioning, and cruise control. This Eldorado Coupe is offered by the seller with receipts from current ownership and a clean Massachusetts title in the owner’s name.

The car was finished at the factory in Frost Orange Firemist (96) with a body-colored landau roof, and it has fender-mounted light monitors, a power trunk-lid release, a keyed alarm system on the left-front fender, and a power antenna, which works intermittently. The headlights were replaced in 2026. The filler panels between the body and the rear bumper have also been replaced, and the seller notes that paintwork was completed on the rear corners under previous ownership. Some flaws around the vehicle are pictured in close-up photos shown in the gallery below.

The Eldorado featured variable-ratio power steering, torsion-bar front suspension, a coil-sprung solid rear axle with Automatic Level Control, and hydro-boost disc brakes, and the seller notes replacement in the past year of brake hoses, calipers, rotors, and pads. The 15″ steel wheels were mounted with 235/75 thin-whitewall tires under current ownership, as well.

The cabin features Antique Saffron Sierra Grain leather, a 50/50 Dual Comfort front bench, a power-adjustable driver’s seat, automatic climate control, a rear defroster, an AM/FM stereo with an eight-track player, and cruise control, which was serviced in preparation for the sale.

A color-keyed steering wheel fronts the 85-mph speedometer, which has a five-digit odometer showing 26k miles, approximately 600 of which were added under current ownership.

The 7.0-liter V8 was factory rated at 180 net horsepower and 320 lb-ft of torque. The seller tells us that its four-barrel carburetor was rebuilt in the past year, and the thermostat, radiator hoses, accessory drive belts, fuel filters, spark plugs, ignition wires, HEI distributor, PCV valve, battery, air cleaner, and engine oil were replaced. He adds that an accumulator pipe for the air conditioning was also replaced, and the system was recharged with R134a refrigerant.

Power is routed to the front wheels via a Turbo Hydra-Matic three-speed automatic, which was serviced in 2026 with a filter, pan gasket, and fluid, per the seller, who reports some seepage from the transmission.
