This is not a Jaguar, this is a Citroen that has been involved in a head-on collision with a Peterbilt truck. Jaguar made their name by producing some of the world's most elegant and enduring automotive shapes. This XJ is an absolute eyesore and William Lyons would be utterly horrified if he saw it.
I would love to own a Jaguar but the deja vu XK is noisy, uncomfortable, expensive and not particularly quick. And the XF is just a re-badged Mondeo that looks, at best, like a bland Volvo/Lexus mongrel. The most elegant saloon on the market today (both inside and out) is the Merc CLS - which was informally codenamed the Jag Fighter by Mercedes themselves. Mercedes did their homework about what Jag drivers want and got it absolutely spot on.
Goodbye Jaguar, you provided a great deal of pleasure for many people for many years. But you have completely lost your way and the brand has now been irrevocably damaged. I have no doubt that this incompetant, unimaginative management will finally succeed where the militant unions and their workforce failed.
