 In October 1959, an extensively revised version of the car with wider windows and 2.4, 3.4, and 3.8-litre engine options became the Mark 2.The 3.8 Mark 2 was popular with British police forces for its small size and performance.The Mark VIII of 1956 and Mark IX of 1958 were essentially updates of the Mark VII, but the oversize Mark X of 1961 was a completely new design of large saloon with all round independent suspension and unitary construction.
