The 365 California used the same chassis as the 500 Superfast but with an evolutionary cabriolet body by Pininfarina. Debuting at the Geneva Motor Show in 1966, just 14 examples were produced (including 2 in right hand drive) before production ended in 1967. Whilst the prototype was built on a 330 GT 2+2 type 571 chassis, production cars featured type 598 chassis. Chassis' were sent to Pininfarina's Grugliasco plant to be bodied and trimmed which were later returned to Ferrari for fitment of the mechanical components. It was presented at the 1966 Geneva Salon.
