The Alfa Romeo 6C 1500 Sport was a successful racing car, winning the Mille Miglia in 1929. The car helped cement Alfa Romeo as a constructor of serious racing cars, and the 6C 1900 was a further evolution of the 1500's winning formula. Improvements like a fully-boxed frame, four-speed transmission, and aluminum cylinder head made the car a competitor. This 6C 1900 has been restored with Le Mans-style spider bodywork and an Alfa supercharger and is presented in excellent driving condition. Only 197 6C 1900s were made and this is one of the best examples in existence.
