In 1962 the entire Westminster range received a facelift primarily to increase power output and interior specification. The Princess MkII also benefit from these changes, and some items of interior trim are improved by Vanden Plas - picnic trays are included for the rear passengers, and the dashboard layout was slightly redesigned.
Mechanical improvements saw a more powerful engine producing 120bhp (90kW) capable of taking the car to a maximum speed of 108 mph. Economy for this engine is around 20 mpg. The car also have a slightly longer wheelbase, and the manual shift gear lever is now floor-mounted. Changes across range include thicker front discs, a larger brake servo and a self-adjusting brake mechanism for rear drums. Changes specific to the Princess model are a re-designed facia layout, and the inclusion of picnic tables for the rear passengers, set into the back of the front seats. Front seats now have squab adjustment, and larger over-riders are fitted to the bumpers.
