Introduced in June 1966, the Viscount was the super deluxe version of the Cresta PC, with similar engine and mechanical components. It was intended to compete against various contemporary premium vehicles. It was fitted with power steering, reclining seats, electric windows, a vinyl roof, walnut dashboard, leather trim, passenger reading lights and picnic tables, a fully carpeted luggage compartment and other accoutrements normally associated with luxury vehicles.

Fitted with the usual 3.3 litre straight-six engine and either two or three-speed automatic transmission, depending on its build date, the car was refined and had a sumptuous ride. Its performance, however, could feel lacklustre. The fuel consumption alone was a not the best, although this was never a major concern with drivers of such vehicles.
