The Fiat 1100-103 was produced from 1953 to 1969 over seven generations. It replaced the old 1100 which was built on the basis of the Fiat 508, the design of which dates back to 1937. To differentiate her from her older sister, she was introduced under the code name 1100-103. The only thing in common between these two cars was the 1098 cc engine, of legendary reliability and flexibility. The last series was presented in 1966. It was badged 1100R (R for Rinnovata - renewed). The lines were more modern, less rounded than the previous series. The engine remained unchanged. The 1100 - 103 was replaced by the Fiat 128, of an entirely new design.
