1939 BMW 328 Roadster
- Engine
- Nearly 2.0L inline-six with hemispherical head, crossover pushrod exhaust actuation, approximately 80 bhp

Chassis 85351 is a late-production example of the BMW 328, one of 464 built before the outbreak of war in 1939 and widely regarded as the most significant pre-war BMW. Powered by an innovative hemispherical-head inline six producing 80 bhp, it has been a regular participant in historic motorsport for several decades, accumulating a well-documented event record across California and beyond. Maintained continuously by two successive owners over roughly thirty years, it remains in active racing-ready condition.
