Chassis BEX385 is a left-hand-drive 1957 AC Ace-Bristol roadster, one of the more powerful and expensive Bristol-engined variants of AC's landmark sports car. Dispatched from the factory in late 1957 for a Houston, Texas dealer, it subsequently passed through French ownership before returning to the United States. It later formed part of the notable Indiana collection assembled by Tom Mittler, and now presents in British Racing Green over black leather.

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.
