The Cadillac Eldorado is a luxury car manufactured and marketed by Cadillac from 1952 to 2002 over twelve generations.

The Eldorado was at or near the top of the Cadillac line. The original 1953 Eldorado convertible and the Eldorado Brougham models of 1957–1960 had distinct bodyshells[1] and were the most expensive models that Cadillac offered those years. The Eldorado was never less than second in price after the Cadillac Series 75 limousine until 1966.

Starting in 1967 the Eldorado retained its premium position in the Cadillac price structure, but was built in high volumes on a unique two door personal luxury car platform.

The Eldorado carried the Fleetwood designation from 1965 through 1972, and was a modern revival of the pre-war Cadillac V-12 and Cadillac V16 roadsters and convertibles.

Second generation (1954–1956)

In 1954, Eldorado lost its unique sheet metal and shared its basic body shell with standard Cadillacs. Distinguished now mainly by trim pieces, this allowed GM to lower the price and see a substantial increase in sales. The Eldorados had golden identifying crests centered directly behind the air-slot fenderbreaks and wide fluted beauty panels to decorate the lower rear bodysides. These panels were made of extruded aluminum and also appeared on a unique one of a kind Eldorado coupé built for the Reynolds Aluminum Corporation. Also included in the production Eldorado convertible were monogram plates on the doors, wire wheels, and custom interior trimmings with the Cadillac crest embossed on the seat bolsters. Two thousand one hundred and fifty Eldorados were sold, nearly four times as many as in 1953.

For 1955, the Eldorado's body gained its own rear end styling with high, slender, pointed tailfins. These contrasted with the rather thick, bulbous fins which were common at the time and were an example of the Eldorado once again pointing the way forward. The Eldorado sport convertible featured extras such as wide chrome body belt moldings and twin round taillights halfway up the fenders. Sales nearly doubled to 3,950.

For 1956, a two-door hardtop coupé version appeared, called the Eldorado Seville at which point the convertible was named the "Eldorado Biarritz". An Eldorado script finally appeared with fender crest on the car which was further distinguished by twin hood ornaments. An extra feature on the Eldorado convertible was a ribbed chrome saddle molding extending from the windshield to the rear window pillar along the beltline. With the addition of the Seville, sales rose yet again to 6,050 of which 2,150 were Sevilles. Eldorados accounted for nearly 4% of all Cadillacs sold.
