The 1965 Series II version featured a five-speed gearbox instead of the overdrive four-speed of the prior year. Other changes included the switch back to a dual-light instead of quad-light front clip, alloy wheels, and the addition of optional air conditioning and power steering. Prior to the introduction of the 'Series II' 330 GTs, a series of 125 'interim' cars were produced, with the quad-headlight external configuration of the Series I cars, but with the five-speed transmission and 'suspended' foot pedals of the 'Series II' cars.
