The Jaguar XK120 is a pivotal moment in time for the British automaker. With so much riding on both the design and mechanical aspects, it was inevitably a success. One that would evolve into the great cars of the 1950's and 1960's, both on the road and the track. With 12,055 made in 6 years, it was undoubtedly a success. This means that many also were subjected to neglect with the launch of newer cars from Jaguar and others. Cars found there second, third and/or final owners. The loss of a fuel pump, or a minor issue caused them to sit, languish and lend themselves to a their future potential as a barn-find. Thus, it is fair to say that the XK120 is the perfect case study for an important but common car that remains a popular car to restore amongst enthusiasts.
