Cadillac segmented its exclusive market in 1957, offering luxury automobiles and then topping them with exclusive, limited production variants that offered buyers immediate visual distinction. The top of the line were the Eldorado’s. Developed from Cadillac's fantastic Motorama cars of only a few years before, they were exotic, luxurious and priced to place them within the reach of only a few discriminating buyers who would accept only the very best and wanted to be recognized for their style and means. The four-door hardtop Eldorado Brougham set the tone but it was matched in drop-top form by the Eldorado Biarritz convertible, uniquely styled with a rounded tail and distinct shark-style fins. The Eldorado Biarritz cost $7,286, more than $2,000 more than a Series 62 convertible, putting them in the stratosphere of Fifties automobiles, yet Cadillac found buyers for 1,800 of them. Loaded with every imaginable power assist and convenience, they are the aristocrats of American automobiles, a quality and distinctiveness that is evident in this 1957 Cadillac Eldorado Biarritz convertible. Beautifully presented in metallic blue with red leather upholstery and interior trim and white top, it has a body color fiberglass "parade boot," chrome wire wheels, wide whitewall tires, air conditioning, WonderBar signal-seeking radio, power steering, power brakes, Autronic Eye headlight dimmer, power windows (one of few "options" on the Eldo Biarritz) and remotely-controlled outside mirror. It has been treated to a high quality restoration and is consistently very attractive and handsomely done. The dual quad engine with bat wing air cleaner is attractively detailed. Overall this Eldorado Biarritz convertible is handsome, orderly, accurate and thoughtfully redone without going over the top. It shows some use since its restoration as well as consistent attention, restoration and condition appropriate to its stature as one of the greatest cars of the golden age of Detroit.
