In 1953 Cadillac unveiled the first Eldorado, widely regarded as the pinnacle of personal luxury cars. Priced at over $7,000—a small fortune then—only 400 were built. Each featured automatic transmission, six-direction power seats, power windows, and, believe it or not, air conditioning. The 1957 Silver Hardtop Brougham convertible offered an automatic folding top and epitomized extra-luxury. With prices starting at $11,000 (up to $14,000 with memory seats), it was perfection on wheels.
