11. Series 70, Eldorado Brougham
Complex Says: In 1957, people cross-shopped Cadillac with Rolls-Royce. The Eldorado Brougham cost more than $13,000, making it more expensive than the Rolls Silver Cloud of the same year. The Eldorado did, however, come with every feature imaginable, including, for the first time in history, power seats with a memory feature.
