1931 Alfa Romeo 6C 1750 Navigation
The powerful Alfa Romeo 6C 1750 was produced in six series between 1929 and 1933. Most of the cars were sold as rolling chassis and bodied by coachbuilders such as Zagato, Touring, and James Young.

The Gran Sport, introduced in 1931, benefited from Vittorio Jano's excellent engineering and design principles. It was an updated version of the 6C 1750 Super Sport from 1929 which had similar specifications. New to the Gran Sport was a shorter wheelbase that was reduced by 50mm and fitted with shorter rear leaf springs.

With its modified Roots supercharger, the 1750 Gran Sport was an invincible race car, one with ample torque for its small chassis.

In total, over 250 Gran Sports were produced, and they provided launch points for several firms, including Zagato, who bodied most of them, and Scuderia Ferrari, who bought and raced them.

This example has lived in Canada for over 50 years and has been in the hands of the current owner/collector for over 30 years. It has competed in the Historic Mille Miglia rally, where it finished as the top Canadian entry. It is a very authentic fourth-series supercharged 1750 that sports all of its original major mechanical components and iconic Zagato Spyder coachwork. It was also the first Canadian-owned and driven car to compete in the Mille Miglia commemorative rally in Italy, where it ran in 1989 and 1990, fittingly returning to the classic open road event for which it had originally been designed, and in which the 6C 1750 once reigned supreme.
