1957 Cadillac Eldorado Brougham

58P020084roadUnited States

Colour: Black over white leather interior with black accents

The 1957 Cadillac Eldorado Brougham was the marque's flagship riposte to Ford's Continental Mark II — a four-door hardtop priced above contemporary Ferraris and Rolls-Royces, featuring a brushed stainless-steel roof, frameless disappearing side windows, rear-hinged rear doors, a memory front seat, and forged aluminium wheels. Of just 400 built in its first model year, this example was once part of the celebrated John O'Quinn Collection and is finished in Black over white leather, consistent with factory build records held in the GM Archives.

Maintenance & restoration

—
Restoration
A comprehensive restoration was carried out, and the original air-spring suspension was replaced with conventional coil springs to improve long-term reliability.
Prose dates this work to the late 1990s, but that is a decade-range only, so the date is recorded as null per extraction rules.
