During the 1950s the Eldorado, Cadillac’s most prestigious and lushly trimmed non-limousine model, continuously grew in importance and stature. By 1956 it bore the distinctive sharp-edged tailfins that would become iconic, which it introduced to the Cadillac line, and featured an exclusive engine equipped with dual Carter WCFB four-barrel carburetors, which along with boosted compression, raised bhp to 305. Combined with a Hydra-Matic transmission improved and re-engineered for smoother shifting, it made for one of America’s finest “personal luxury” cars – and among the most expensive convertibles in the country.

This was one of Cadillac’s lowest-production models in 1956, with the Eldorado Biarritz convertible selling only 2,150 copies.

The example offered here is documented by a copy of its original build sheet, which confirms that it was delivered in this beautiful and striking color, Bahama Blue, inside and out, to a buyer in San Francisco. Its restoration is well preserved and, typical of the cars in this collection, has received excellent maintenance and appears in wonderful condition, with straight, properly fitted body panels, and only the most minor wear to the cream and blue leather upholstery. The car has recently undergone a full, professional engine rebuild by the collection’s own shop, and retains its original gold “sabre” wheel covers and “parade boot” top cover, as well as a soft top cover and jack in the trunk.

A longtime favorite in the Calumet Collection, this Cadillac demonstrates 1950s opulence at its very best.
