In 1965 the Ferrari 330 GT 2+2 received an update, cars that would become known as the Series II cars. As compared to the Series I, this version featured a five-speed gearbox instead of the overdrive four-speed. Other changes included the switch back to dual head-lights instead of quad-lights in the front, alloy wheels, and the addition of optional air conditioning and power steering. Production of the smaller 330 GTC and GTS models overlapped with the GT 2+2 for more than a year.
