The Jaguar XKR is one of those rare grand touring cars with seemingly endless talents. It makes you a happy driver, it coddles you in comfort while egging you on to insane speeds, and it makes other drivers British racing green with envy.Based on the lovely XK8, the XKR keeps a secret under its hood - a magnificent 370-horsepower V8, supercharged with a growl entirely appropriate to this brand. While the 290-horsepower XK8 is powerful and expensive enough at $66,200, the $81,800 XKR convertible makes a compelling argument for the best way to spend those future lottery winnings. Next Page
