Colour
Midnight Blue

Chassis 1923/L is a left-hand drive Aston Martin DB5 Convertible — one of only 123 built and fewer than 40 in left-hand drive configuration. Delivered with optional Normalair air conditioning and retaining its original engine, the car has been known to the Aston Martin Owner's Club for decades. Following a concours-focused restoration by Steel Wings in the early 2000s, it accumulated an exceptional record of international concours victories including Pebble Beach, Amelia Island, Villa d'Este, and multiple Lime Rock and Greenwich awards.

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.
