A 1957 Buick Century Caballero Estate Wagon, one of only two model years the pillarless four-door hardtop wagon was produced. Restored in 2012 under a previous California owner, the car received a custom teal and white paint scheme alongside subtle modifications including a shaved body, engine-turned dashboard, and a triple-carbureted 401 cubic-inch Nailhead V-8 paired with a modern GM 700R4 transmission and coil-over suspension. Reportedly lightly used since the restoration was completed.

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.
