2005 Jaguar XK

The Jaguar XK should be getting a little long in the tooth, having been introduced in 1996, but it's not. Its styling remains contemporary because it's so classically sleek and gorgeous, while mechanical and electronic upgrades, along with some sheetmetal tweaks, have enabled the big Jag to keep pace with the competition. Although not much if any competition exists, because the car is pretty much in a class by itself. Not really because of its engineering (power, handling and brakes), but because of its exclusivity. Its Jaguar-ness.
