1959 Cadillac Eldorado Biarritz = $324k

In the late 1950s, Cadillac was the undisputed heavyweight champ in the full-sized luxury car market in North America. Cadillac used the nameplates "Eldorado Seville" and "Eldorado Biarritz" to distinguish between the hardtop and convertible. The 1959 models came near the end of the 3rd generation. The 1959 Cadillac is remembered for the largest tailfins ever and dual bullet tail lights.

While the 1959 Eldorado was misunderstood in its day, collectors today recognize the car's combination of power, presence, and unbridled extravagance.

The Eldorado featured the ultimate engine of the late 50s, the Q-code 390-cu.in. V-8, topped by three two-barrel Rochester carburetors producing 345 hp.
