The 18/80, introduced in 1928, was the first specially designed MG and it was also the first to carry the radiator design, which was to become a distinguishing feature of the marque for the next thirty years.

Having a Morris six-cylinder engine, the 18/80 became known as the 'Quick Six'. A range of body styles were available, from an open two-seater up to a saloon. The Mark I Speed Model of 1930 had a light, fabric, four-seater body and to live up to its name, it was sold with a guaranteed top speed of 80 mph.

This car was found on Dartmoor in the 1950s, when the MG Car Company rebuilt it and fitted an engine from a Mark II saloon.
