The Oxford was updated for 1956 with a new optional two-tone paint scheme, fluted bonnet and small rear fins. Inside the bench seats trimmed in leather remained but the instrument cluster was revised and a new dished steering wheel fitted. The engine now produced 55 hp (41 kW) following an increase in compression ratio though the top speed and acceleration remained the same. A semi-automatic, two pedal, "Manumatic" transmission with centrifugal clutch with vacuum operation coupled to gear changes was optional.
Independent front-suspension with forward torsion bars continued to promise "above average comfort" for the car's occupants.
The woody Series III Traveller was replaced by the Series IV in 1957, though the saloon remained in production until the Pininfarina-styled Series V was introduced in 1959. 58,117 Series III and Series IV Oxfords were built.
Motor magazine tested a Series III manumatic equipped saloon in 1957 recording a top speed of 74.4 mph (119.7 km/h), virtually unchanged from the Series II and acceleration from 0–60 mph (97 km/h) in 30.5 seconds, adversely affected by the Manumatic option. Fuel consumption of 27.0 miles per imperial gallon (10.5 L/100 km; 22.5 mpg-US) was found. The test car cost £898 including taxes of £300.
This car was the basis for the Hindustan Ambassador, since 1957 which continues to be built in India some 50 years after the Oxford III's demise, though with a few notable styling updates but keeping the original look, albeit with modern powertrains.
