6. 1953 Cadillac Eldorado
The 1950s brought post-war optimism and rising standards. So, Detroit responded with fresh models and more power. But nothing could match the highly exclusive Cadillac Eldorado in 1953. Cadillac based it on the Series 62 convertible model. However, the Eldorado was the first true personal luxury car.
Also, it was the most expensive Cadillac at that time. In fact, it cost $2,000 more than the rest of their lineup. The main features included an advanced one-piece wraparound windshield and an interesting belt line with a slight dip before the rear fenders. Also, the raised tail lights were the precursor for their famous chromed fins that arrived a few years later.
The power came from the same 5.4-liter V8 as the rest of the 1953 models. But Cadillac only made 532 Eldorados that year. Despite the limited availability, the popular Eldorado stayed in their portfolio for 50 years.
