The Cadillac Eldorado Biarritz is the epitome of the over the top nature of '50s automotive design. As such, we named it as the greatest Cadillac of all time. This is a stunning drop top example of the vehicle, and the price got up to $130,100.00 before the auction ended. It didn't meet the reserve, so if you have more than $130k sitting around, this could still be yours. Snoop Dogg would be jealous.
