A mark with incredible heritage and reputation, Jaguar has long been the quintessential enthusiasts' car maker, with remarkable success in motorsports and home to history's most reveled sports cars and sedans. One of those cars was the XK120 race car, a truly revolutionary car for its time. An updated version of the car was the 2006 XK Series, redesigned for the first time in 10 years. Chief designed Ian Callum penned the car's shape, and his previous stint as Aston Martin's lead designer shows up in the car's details.
