Deal of the week: Jaguar XJ

Jaguar is offering a free model upgrade on its XJ, worth £7,200. The deal lets buyers specify a Portfolio version of the luxury saloon for the same price as a Premium Luxury. By upgrading, drivers get a reverse parking camera with guidance, an eight-inch touchscreen, 20-inch alloys and adpative headlights.

The XJ is Jaguar's high-technology flagship. Not only is it the most distinctive road car the firm has ever designed, it's also more fun to drive than many rivals, including Mercedes and BMW. Three exceptionally powerful and quiet engines are available - two petrols and one diesel. All cars come loaded with luxury equipment.
