In the 1920's, Alfa Romeo was fortunate to steal Vittorio Jano away from Fiat (Jano had designed some of Fiat's most successful Grand Prix cars). Working from the 1.5 liter 6 cylinder platform, Jano designed the new and now famous 6C 1750 (1.75 liter 6 cylinder). Produced from 1929 through 1933, 2579 6C 1750's were produced in three variations: single overhead cam Turismo, twin overhead cam Gran Turismo, and and the Gran Sport (a supercharged Gran Turismo). The cars were sold as a rolling chassis and predominantly bodied by either Touring, Castagna, or Zagato. These cars had a tremendous racing record in the hands of teams such as Scuderia Ferrari. That's me seen riding in a friends 6C 1750 Gran Turismo with Zagato body (arguably the best looking body to grace the 6C chassis). Zagato made its reputation building bodies of the "Superleggera" type - basically aluminum body panels over a steel tube framework. I remember the car being quite fast and having wonderful brakes for a 1930's vintage automobile. It wasn't the easiest car to drive as it wanted to be kept at higher revs, however, it was certainly a memorable ride.
