Improved version of the Mk.VII, the Mk.VIIM was marketed from 1954 to 1957 and produced in about 10,000 units. The 3442cc 6-cylinder engine derived from the Mk.VII, which was however upgraded (up to 190 horsepower) and made brighter thanks to a different gear ratio. The bodywork received more enveloping bumpers than those of the Mk.VII.
