The 1958 Cadillac Eldorado Biarritz is widely regarded as the pinnacle of that model year's lineup, distinguished by its 335-horsepower V-8 engine with triple two-barrel carburetors and lavish standard equipment. This example, finished in original black over red leather, underwent a frame-off restoration in 1991 and subsequently spent approximately fifteen years in the noted Florida collection of Dr. Edward and Joanne Dauer before passing to a further private collection. It has earned both AACA National Senior First Prize and Grand National honors, as well as a Cadillac-LaSalle Club National First Prize.
