Description:

1929 Alfa Romeo 6C 1750 Super Sport
Chassis No. 6C0312896
A well-documented, third-series 6C 1750 Super Sport, one of approximately 120 built in 1929. Delivered new as a rolling chassis to the UK and originally fitted with James Young coachwork, it was later rebodied in the early 1990s as a Zagato-style Spider. The car underwent a thorough refurbishment by Phil Reilly & Co. (1997–2000) and has since proven itself in historic events, including the 2001 Mille Miglia. Currently in the process of gaining FIVA certification.
