History
The Rover P4 series was a group of saloon automobiles produced by the Rover Company from 1949 The Rover P4 was a sedan manufactured from 1949 to 1964. It was then replaced by the much more modern Rover P6 .All P4 models had 4 doors. The designation P4 was a manufacturer code that designated the model group, but was not used colloquially by customers. These called their cars. e.g. “Rover 95” etc.
The last models in the P4 family were the Rover 95 and Rover 110 . When they were introduced in 1962, they looked a bit old-fashioned a 4 door saloon with single front seat so 5-6 seats. Later they got door panels made of sheet steel (instead of aluminum) and electric windscreen washers.The list price for the 110 was £1,143 or for the 90 £1,023 (plus tax). An overdrive was standard equipment; the “Roverdrive” automatic was no longer available.The distribution of weight was 56% to the front axle, 44 % at the rear axle
Both models had the same change-controlled engine with a displacement of 2625 cm³. The old engine produced 123 bhp (92 kW) with a more powerful engine the Weslake head 110 and overdrive was standard on the 110 on the less range model the 95 this had 102 bhp (76 kW) and was fitted with a higher final drive ratio at 3.9:1.

The interior is virtually the same for both models. It is roomy, attractively appointed and finished in true Rover style. Seats are upholstered in fine quality hide, thick pile carpets cover the floor and selected Walnut is used for facia and window garnishings. The wood-panelled facia is in keeping with the tasteful design of the interior as a whole. Instruments and controls are placed in front of the driver in the most practical andconvenient positions. All switches can be operated by a flick Of the finger and there are indicator lights to warn that oil pressure is low, that the cold start control should be returned to its normal running position, that the handbrake has been inadvertentlyleft on or the fluid in the braking system needs replenishment.
Both models were replaced after 1964 by the much more modern new Rover P6 . In total 3,680 model 95) and 4,620 model 110 were produced
