There were three Deauville variants: the early series 1 (1970–1974: serial number 10##, 11## and 12##), late series 1 (1975–1977: serial numbers 14##) and the series 2 (1978–1985: serial numbers 20## and 21##).
One Deauville station wagon was made for Mr. De Tomaso's wife. There were also two amoured Deauvilles produced, one for the Belgian Royal Family and one for the Italian government. One of these cars is displayed in the Museo delle Auto della Polizia Di Stato in Rome
