1929 Alfa Romeo 6C 1750 Super Sport / Gran Sport

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.
