General Motors scored a hat trick with the 1953 Motorama traveling shows. All three of the upscale divisions, Oldsmobile, Buick and Cadillac, had prestige convertible “idea cars,” dramatic in design but close enough to the production models that they were ready to manufacture. Named Fiesta, Skylark and Eldorado, respectively, they entered limited production during the year. Based on the Series 62 convertible, the Eldorado differed in having a wrap-around windshield, a portent of GM’s future, a distinctive dipped cockpit contour and came with a hard “parade boot” to cover the top when lowered. Just 532 were built, at a price 90-percent above that of the Series 62 convertible.

The glamorous Eldorado and its hardtop sister car, the Eldorado Seville offered, for 1957, even more exciting and modernized styling than the previous year. They were more streamlined with an almost three-inch lower silhouette without sacrificing the precious interior spaciousness. The distinctive new styling was matched by its smart looking interior, which combined full luxury with the benefit of maximum durability.

The Cadillac Eldorado Biarritz is powered by a 365-cid V-8 engine that is equipped a four-speed automatic transmission. The odometer shows 74,265 miles which the owner believes to be original. Among the many conveniences on-board are a parade boot; plus six-way power seat, power windows, power locks, power steering, power antenna and power brakes. Other amenities include: EZ-eye glass, Wonderbar radio and Saber-Spoke wheels.
