Eldorado Cadillac History 1958

Eldorado Cadillac Models & History 1958

1958, Cadillac stood more or less pat on a winning hand. Styling changes involved minor sheetmetal reshaping and ornamentation shuffling, and all models acquired the new four-headlamp system, first seen at Cadillac on the Brougham, in line with an industry trend. Eldorado performance was substantially improved with the adoption of three two-barrel carburetors, which boosted output to 335 bhp, 25 bhp up on the single-four-barrel engine used where in the line. The Seville 40 and Biarritz, which consistently bore identical price tags, rose a startling $762. The timing of such a substantial increase proved to be ill-advised in this deep recession year and sales fell by more than half.

On 62 Eldorados a V-shaped ornament and model identification script were mounted to the deck lid. The two luxury Cadillacs also had ten vertical chevron slashes ahead of the open rear wheel housings and crest medallions on the flanks of tailfins. Broad, sculptured beauty panels decorated the lower rear quarters on Eldorados and extended around the wheel opening to stretch along the body sills.
