The Bugatti Veyron of its day. Long, low, sleek with a great big six under its hood, the XK120 was the fastest car you could buy at the time, with an incredible top speed of 120 mph.
Shelby designed its own coil-sprung chassis, and fit the massive Ford 427 V8 to create the incredible Cobra 427. It's still one of the quickest cars ever built and it's somehow still in production today.
