Cadillac Eldorado Biarritz Convertible

The 1959 Cadillac Eldorado Biarritz Convertible is perhaps the most recognizable American automobile ever produced. Its towering tail fins, reaching 42 inches from the ground, represent the absolute zenith of the fin era and have become the universal symbol of 1950s American automotive excess, optimism, and style. The Biarritz was the convertible version of the Eldorado line, and it remains the most visually dramatic car of its generation.

The 6,390cc (390 cubic inch) V8 engine produced 345 horsepower through three two-barrel carburetors, making the Biarritz the most powerful Cadillac available. This engine provided effortless acceleration for the substantial car, with the Hydra-Matic automatic transmission delivering seamless, silent gear changes that complemented the car's luxury character.

The 1959 Cadillac's design, created under the direction of Harley Earl's successor, Bill Mitchell, represented the culmination of a design trend that had begun in the late 1940s when Clarence 'Misterc' Cadillac's designers drew inspiration from the Lockheed P-38 Lightning twin-boom fighter aircraft. Each subsequent year, the fins grew taller and more elaborate, reaching their apex in the 1959 models. The twin bullet taillights embedded in each fin added to the Jet Age aesthetic.

The Biarritz convertible top was power-operated, folding beneath a flush-fitting boot cover that maintained the car's clean lines when lowered. The convertible experience in the Biarritz was grand-scale open-air motoring: the massive car, the powerful engine, and the dramatic styling combined to create an experience of rolling American luxury that was unmatched.

The interior was quintessentially 1959 Cadillac: expansive, luxurious, and equipped with every available convenience. Power windows, power seats, air conditioning, signal-seeking radio, and automatic headlight dimming were among the features available. The dashboard design, with its aircraft-inspired instrumentation and push-button controls, reflected the Space Age optimism of the era.

Cadillac produced 1,320 Eldorado Biarritz Convertibles for 1959, making it the most exclusive of the regular-production Cadillac models. At $7,401, it was the most expensive Cadillac available (excluding the discontinued Brougham), placing it at the absolute summit of the American luxury car market.

Today, the 1959 Cadillac Eldorado Biarritz is one of the most iconic and sought-after American cars. Its extreme styling has made it a design landmark, a cultural symbol, and a blue-chip collector car. Well-restored examples regularly command prices well into six figures, and the car remains one of the most photographed and recognized automobiles in the world.

The massive body is prone to rust in floors, rockers, trunk, and quarter panels. Chrome quality is essential for top values — rechroaming the extensive trim is extremely expensive. Check the power convertible top mechanism for proper operation. The triple-carburetor engine should be inspected for proper synchronization. Air conditioning system condition should be verified. Check all power accessories, as period motors and switches deteriorate.

1,320 Eldorado Biarritz Convertibles were produced for 1959 at the Cadillac factory in Detroit, Michigan. The Biarritz was the premium convertible in the Cadillac lineup.
