It's hard to disagree with Jay Leno that the XK120 is one of the most beautiful cars ever built. Yet few people know that Jaguar
conceived and constructed the car in just a few months. You may have seen the Denim Chin's look at his modified XK120 roadster, but this is the first time the late-night talk-show host has put his breathtakingly gorgeous baby-blue coupe in the spotlight. History was made when the roadster debuted at the 1948 Earls Court Motor Show, posting a top speed of 120 mph to make it the world's fastest production car.
