The first Sports car from Jaguar not to bear the SS name, the XK120 was produced from 1948 until 1954.
Built as a testbed and showcase for then XK in-line 6-Cylinder engine, the prototype created such a sensation that Sir William Lyons (Chairman of Jaguar) ordered the XK120 to be put into production.
The first 242 cars built were constructed on a wooden frame with aluminium body panels, but in 1950 Jaguar switched to an all-steel body, adding 51kg to the overall weight.
The "120" designated the top speed of the car - 120 mph - making it the world's fastest production car when it the XK120 was launched.
The first production car (Chassis number 670003) was delivered to actor Clark Gable.
The rear wheel covers see on t he car here are called "spats". Most XK's have them removed because a) they rust out very easily and b) they look like crap.
