Cadillac’s bold moves during an economic slump in 1975 improved sales over 1974. The chief achievement was the new Seville, a Nova-sized sedan notable for its luxury fittings and hefty $12,479 price tag. The Eldorado, meanwhile, continued to be successful with 44,752 sold in 1975. The vast majority were coupes, and Cadillac announced that 1976 would be the last year for the vast soft top Eldorado convertible. The 1975 Eldorado lost its rear fender skirts, the grille became a bold egg-crate design, and the rear quarter windows were enlarged and extended down to the rear fender line. Parking and turn signals were relocated to the front bumper.

Despite the high-energy ignition and optional fuel injection instead of a 4-barrel carburetor, the 500 cid V8 was quoted as a dismal 190 net horsepower for 1975. The Eldorado’s Turbo Hydra-Matic transmission still featured a side-by-side setup with the engine, and a unique internal chain drive. Front suspension was by torsion bar with rear coil springs and a self-leveling option.

The Custom Cabriolet package continued for the Eldorado Coupe, with a “halo” half vinyl roof that featured a chrome bar across the top. Behind it was padded vinyl and ahead of it was a sunroof, set in the painted roof.

The 1975 Eldorado was available with an optional leather interior (standard on the convertible) and a bench front seat with folding center armrest. Automatic climate control was now standard, along with power door locks, a 6-way power adjustable seat, an AM/FM stereo radio, and steel-belted radial tires.

Popular options included automatic leveling, padded vinyl roof, power sunroof, tilt/telescopic steering column, remote trunk release, rear window defogger, AM/FM stereo with 8-track, cruise control, tinted glass, heated front seats, and automatic headlight dimmer.

Cadillac climbed to 9th place in the U.S. market, ahead of Chrysler, AMC, Lincoln, and Imperial. Chrysler finally gave up on Imperial this year, canceling a marque that dated back to 1927.
