In October 1964 the final Series V version of the Saloon saw an upper body restyle, (also applied to the Hawk Saloon and the Rootes Group's smaller Hillman Super Minx and its derivatives) with a flat roofline and rear window, six-light side windows and a larger, taller windscreen.
Intended to match BMC's Rolls-Royce engined Vanden Plas Princess 4-litre R the Imperial shared the basic specification and performance of the Super Snipe with the addition of a vinyl roof, fully reclining front seats, automatic transmission and hydrosteer power steering as standard.
