General Description & Specifications

As the table below demonstrates, up to 1953-1954 right-hand drive cars predominated, which was in keeping with other contemporary high quality Italian cars. With the introduction of the Series II cars in 1954 an increasing proportion was fitted with left-hand drive so that by 1957-58 about 70% of B20s and 100% of B24s were left-hand drive. The production information is listed below:
