The Jaguar XK 120 was originally intended to serve as a stop-gap solution for the "London Motor Show" in October 1948 and to be flashy enough to create an eye-catching effect at the first fair after World War II. Jaguar wanted to use the show as a platform for presenting its new in-line six-cylinder engine for a new high-speed limousine. However, body engineering at Pressed Steel hit a snag and could not be finished in time. So, the company made the spur-of-the moment decision to fit and present the engine in a speedy sports car. Over the course of the decades, this Jaguar became increasingly popular with fans as its authenticity cannot be beat.
