1958 Cadillac

The 1958 Cadillac Eldorado Brougham was Cadillac’s hand-built flagship sedan, positioned above the conventional Eldorado and distinguished by its four-door hardtop body, rear-hinged rear doors, stainless-steel roof, and extensive standard equipment. Production for 1958 totaled 304 cars, making this one of the rarest postwar Cadillac series. The model was assembled in Detroit by Cadillac/Fleetwood rather than by an outside coachbuilder; the coachbuilt character came from its low-volume construction, unique body shell, and highly specified trim. Cadillac’s 1957–58 Brougham is historically important as the first production car with air suspension and as one of the most elaborate American luxury sedans of the era. For 1958, the Eldorado Brougham used Cadillac’s 365-cu.-in. OHV V8 rated at 335 hp, with triple two-barrel carburetion and automatic transmission. The car rode on a 126-inch wheelbase and used a unique four-door hardtop body with rear-hinged rear doors, pillarless construction, and Cadillac’s advanced air-suspension system. Contemporary and archival references also identify the model as a low-volume, hand-finished luxury sedan with standard power equipment and extensive bespoke trim, making it mechanically and conceptually distinct from regular-production Cadillacs. Chassis 58P031725 is an example of the 1958 Eldorado Brougham, one of Cadillac’s rarest postwar models and a significant survivor from the 304-car 1958 run. Its present market standing is defined by rarity and originality.
