This 1975 Oldsmobile Delta 88 Royale convertible was initially sold at Steele-Hopf Oldsmobile in Blue Island, Illinois, and is said to have remained in a collection for 20 years before the selling dealer’s 2024 acquisition. Now showing 8k miles, the car is finished in Crimson Red over white leather and powered by 455ci V8 linked with a three-speed automatic transmission and limited-slip differential. Equipment includes a power-operated white convertible soft top, power steering, power-assisted front disc brakes, and 15″ steel wheels with wire-style covers in addition to a power-adjustable driver seat, air conditioning, cruise control, a push-button AM/FM radio, an Alpine CD stereo, and power windows, locks, and mirrors. This 88 convertible is offered in Oregon with a build sheet, a manufacturer’s certificate of origin, manufacturer’s literature, and a Washington title.
The body is finished in Crimson Red (72) and features a power-operated white convertible soft top, chrome bumpers, sport side mirrors, a power antenna, and an outside thermometer affixed to the left door.
The 15″ steel wheels wear wire-style covers are mounted with 225/75 Michelin XA4 All Seasons narrow-whitewall tires. The car is equipped with power steering and power-assisted front disc and rear drum brakes.
The split front bench seat and rear bench are upholstered in white leather and joined by color-coordinated door panels. Woodgrain trim accents the cabin and appointments include a six-way power-adjustable driver seat, air conditioning, cruise control, a push-button AM/FM radio, an Alpine CD stereo, a digital clock, and power windows, locks, and mirrors.
The wood-trimmed steering wheel is mounted to a tilting column and fronts a horizontal-sweep 100-mph speedometer and gauges for fuel economy and level. The five-digit odometer shows 8k miles.
The 455ci V8 is equipped with a four-barrel carburetor and was factory rated at 190 horsepower and 350 lb-ft of torque.
Power is sent to the rear wheels through a three-speed automatic transmission and a limited-slip differential.
The current Washington title carries a “Classic” brand.
