1929 Alfa Romeo Zagato style 6C 1750 SS

This Alfa Romeo 6C 1750 ran in the 2001 Mille Miglia. It is currently going through the FIVA certification.

Price has just been reduced to $750, 000. 00 US from $800, 000. 00 Can help with shipping. Car needs nothing to run smoothly in vintage events having been recently serviced. Will consider trade/ cash with interesting postwar car like a Jaguar XK150, XK120, etc.

According to the most recent FIVA this is a "nicely original 3rd series Super Sport. The chassis No rightly coincides with the engine number .."

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.
