1959 Cadillac Eldorado Biarritz

Posted by Chauncey Koziol on Friday, August 30, 2024

No other car captures the essence of the “jet age” quite like the 1959 Cadillac Eldorado, with styling that could have been copied from a fighter plane. While many believe that Cadillac’s tailfins were a product of the 1950s, their use actually dates back to GM’s 3/8-scale “Interceptor” design studies of the early 1940s, which were inspired by the radical P-38 Lightning fighter aircraft of World War II.

Available in Biarritz convertible and Seville hardtop form, along with the hand-built Brougham four-door hardtop, the Eldorado was Cadillac’s undisputed image leader for 1959. Standard Eldorado equipment included a heater, fog lamps, air-assisted suspension, a radio with a rear speaker, power windows, a six-way power front seat, power door locks and whitewall tires. Power was provided by the top Q-code 390 cubic inch V8, which thumped out 345 horsepower with a trio of two-barrel carburetors, teamed with a four-speed Hydra-Matic Drive automatic transmission.

Just four options were available for the Eldorado – air conditioning, cruise control, the Autronic-Eye automatic headlight dimmer and E-Z Eye glass, along with a no-cost bucket seat option for the Biarritz. Both the Biarritz convertible and the Seville hardtops carried a lofty base price of $7,401 when new, with only 1,320 examples of the Biarritz produced.
