Built from 1951-57. Replaced the Mk V, there was no Mk VI Jaguar The Mk VII got the new XK OHC engine and a modern and streamlined looking body, featuring fully integrated headlights and mudguards. In place of its predecessor's flat windscreen, the Mark VII design included a two piece front screen. It was only available as a 4 door sedan. In 1955 there was an update, the Mark VII M, it could be distinguished from its predecessor most easily by the horn grilles beneath the headlights. These replaced the formerly integrated auxiliary lamps which were now perched on the bumpers
