Both the coupe and convertible versions of the new Eldorado received several facelifts from 1971 through 1978.
The initial model was fitted with an 8.2L V8 unit delivering 370 hp, but Cadillac decided to replace it with a newer 7.0L V8 (producing 180 hp) in 1977 - a year after discontinuing the convertible variant. Also in 1977, the Cadillac Eldorado underwent its first important exterior chances, featuring a revised front grille. As far as the convertible Eldorado was concerned, the last 200 units were sold under the name of ‘Bicentennial Edition’ in 1976.
