Introduced early in June 1966, with the same engine and mechanical components as the Cresta PC, the Viscount was the super de-luxe version of it. It was supplied as standard with power steering, electric windows, reclining seats, a vinyl roof, walnut dashboard, inertia reel seat belts front, and even a heated rear window. Areas of the grille and headlamp surrounds were blacked out to give a classier look and the tail-lights had a chrome overlay. The dark green, blue or maroon paintwork featured simulated, hand painted coachlines, along each flank, to give the car a coachpainted appearance. The outer pair of the quad, five inch, sealed beam headlamps were twin filament, giving the car four main beams. The Viscount also came with wider tyres and rims than the Cresta (7.00-14in on 5" rims rather than 5.90-14in on 4.5" rims). All PC 3.3 had twin tail-pipes. The standard transmission option was GM's Powerglide 2-speed automatic system, but a four speed manual gearbox was available, initially on the UK market at a saving of £85: elsewhere the manual gear box was a no-cost option. In the third quarter of 1970 the two-speed Powerglide automatic was replaced with a GM 3-speed automatic transmission.
