Inspired by the Orleans, Eldorado Brougham and Park Avenue show cars of 1954-55, the 1957 Cadillac continued with its evolutionary styling. There were 10 body style, all with the center posts eliminated (except for the Series 75 7-passenger sedan). At the high-end of Cadillac's luxury car offerings, was the Eldorado Brougham, priced at over $13,000. It was a low-slung hardtop sedan, with center opening doors and a brushed stainless-steel roof.
