A rare 1935 Cadillac V-16 Imperial convertible sedan, one of only six bodied in this configuration on a total production run of fifty V-16 chassis that year. Delivered new through the Hoosier Cadillac Company of Indianapolis, the car passed through several notable hands before a comprehensive restoration by acclaimed restorer Steve Babinsky earned it a First in Class award at the 1991 Pebble Beach Concours d'Elegance. It subsequently accumulated AACA Grand National honors before entering prominent collections.

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.
