Jaguar XK 120 was a most typical British sport-car, but went on successful sale firstly in US. The famous movie star Clark Gable purchased the first XK120 from its mass-production, which made it so popular at that time. In fact, it really succeeded in powerful dynamic system and attractive appearance. On speed, it ran up to 120 mph to get the name of XK120 and won Speed Champion of the day. On appearance, the slender bodywork took an integral shape of graceful curve. The successful sale in US was ascribed to the shortage of supplies as high-grade petrol.
