Only 1,800 Cadillac Eldorado Biarritz convertibles rolled off the line in 1957, making this stunning beauty a rare treat. From the mirror-finish Bahama blue paint, to the immaculate matching blue and chrome interior, this immaculate car underwent a no-expenses spared full restoration. The 1957 Cadillac Eldorado Biarritz was the pinnacle of automobile ownership for many Americans in the 50s, and still is to this day.
