Jaguar took 10 years to change the design of its popular XK coupe. Finally, Jaguar is hoping that its new coupe/convertible Jaguar XK will give a big boost in sales. The new Jaguar XK coupe has a completely aluminum alloy body. While it still has a V8 engine it still gets from 0-60 in less than 6 seconds. It comes standard with a navigation system, reverse parking radar, bi-xenon headlights, multi CD audio, keyless engine start, steering wheel paddle shifters and memory seats. The Jaguar XK Coupe went on sale April 17th and will cost you $75,550 for the coupe and $81,500 for the convertible.
