18. 1954 Jaguar XK120
William Lyons, the owner of Jaguar, had a heavy hand in designing the XK120, creating the car in a ridiculous two weeks. At the time, it was probably the most dramatic car on the road, and it had 120mph top speed to back up the attention it drew. The car was originally going to be a limited run, but the public made sure they wanted more. The car also later had big success on the race track.
