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.

This car's public record is built from its auction and competition history. Register your ownership and privately add your own records to make it a verified Legacy Metrics passport — provenance that backs your car's value at sale and gives your insurer evidence to price against. Roy reviews and verifies every registration personally.

Each chassis record is compiled from public auction archives and links to its source material. Ownership, competition and maintenance entries are extracted from those catalogue listings by an LLM, which can make mistakes — please contact us with any corrections. The summary is Legacy Metrics’ own writing; we do not reproduce catalogue text.

“Full” and “partial” documentation labels indicate how well each entry is corroborated in the underlying sources, not an audit of the car’s physical paperwork. Names of recent or living owners are withheld for privacy.
