1959 Cadillac Eldorado Biarritz Convertible
Fins soaring over four feet into the sky announced the arrival of Detroit’s most audacious creation, a convertible that redefined automotive extravagance. At 225 inches long with a 130-inch wheelbase, the massive proportions exceeded even today’s full-size luxury sedans by substantial margins.
The stratospheric $7,401 price tag (equivalent to about $77,500 today) positioned it as an exclusive luxury purchase when average cars cost $2,000-$4,000.
The dramatic styling featured massive fins, created as GM’s response to Chrysler’s radical 1957 redesign. Aviation influences extended throughout the design, from jet-inspired tailfins to front parking lights resembling B-52 bomber air intakes.
Distinctive “Eldorado” script appeared behind the front wheel openings, while broad body sill highlights curved over the rear fender profile.
The top-specification Q-code 390 cubic inch V8 generated 345 horsepower through three two-barrel carburetors, paired with four-speed Hydra-Matic automatic transmission.
Standard luxury appointments included air-assisted suspension, power windows, six-way power front seats, power door locks, fog lamps, and AM radio with rear speaker. Optional bucket seats were available at no cost, with only 99 Eldorados receiving this rare feature.
Production remained exclusive with only 1,320 Biarritz convertibles built, making it roughly 10% of Series 62 convertible volume. The model’s unprecedented fins would be dramatically reduced for 1960, making this the ultimate expression of America’s jet-age automotive design philosophy.
