1956 Austin-Healey 100 M 'Le Mans'

BN2-L/232304roadUnited Kingdom
Engine
Inline-four, race-prepared unit by Dennis Welch Motorsport (original engine included in sale)
Colour
Reno Red

One of only 640 factory-built Austin-Healey 100 M 'Le Mans' models, this 1956 example — chassis 232304 — was completed in May 1956 in Reno Red and shipped new to Chicago, Illinois. The 100 M model grew directly from the company's successful 1953 Le Mans programme and incorporated the same engine and chassis upgrades offered through the Le Mans modification kit. Spending decades in Alabama before moving to the UK in the late 1990s, the car was subsequently prepared for historic competition by Dennis Welch Motorsport, with a race engine, gearbox, competition fuel tank, and uprated suspension fitted. The original engine is retained and accompanies the car.

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.
