1956 Austin-Healey 100 M 'Le Mans'
- 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.
