1955 Austin-Healey 100 M BN2
- Engine
- 2.66L OHV inline-four, 110 bhp, four-speed manual with overdrive

The Austin-Healey 100M is one of only 640 factory-built examples of this limited variant, produced between 1955 and mid-1956. Distinguished by a louvered bonnet, twin-tone paintwork, and a full Le Mans specification engine package — hotter camshaft, larger carburettors, dished pistons, and cold-air induction — the 100M offered around 110 bhp from the 2,660 cc inline four. This particular car has been restored from the ground up to concours standards, with body, engine, and chassis numbers verified by the British Motor Industry Heritage Trust as matching original factory records.
