The Fiat X1/9 was designed by Marcello Gandini at Bertone, going on sale in 1972. In 1982, the car became the Bertone X1/9 with full production moving to Bertone. Fiat withdrew from the US market in 1982, so sales of the Bertone X1/9 in the US transferred to International Automobile Importers Inc. As US sales declined, in 1987 Bertone experimented with a fully convertible Bertone X1/9 Spider. The model failed to progress beyond the prototype stage; sales of the targa top model ended in 1989
