Chassis AM300/3/1564 is a 1958 Aston Martin DB Mark III, a left-hand-drive fixed-head coupé representing the final and most refined evolution of the David Brown DB2 lineage. Delivered new to the celebrated S.H. Arnolt dealership in Chicago on 23 June 1958, it passed to a single Michigan owner who retained it for over five decades. Powered by the twin-cam three-litre DBA straight-six, it features the model's distinctive grille derived from the DB3S racers and was among the first Aston Martins equipped with front disc brakes.

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.
