The XJ's interior is looking a bit dated these days next to newer rivals, but it still has a wonderful ambience. Up front, the diamond-quilted seats (embossed with some questionable '575' branding) come with a wide range of adjustment, and those in the rear are treated to plenty of leg room; there’s little reason to opt for the long-wheelbase variant.

Buyers will be able to choose from four trim levels – SE, Sport, M Sport and M Sport X. Even entry-level SE comes with plenty of equipment, including cruise control, sat-nav, 17in alloy wheels, front fog lights and dual-zone climate control. Sport models additionally receive sports seats, black gloss exterior trim, LED headlights and larger alloy wheels.
Antifreeze, as its name suggests, stops the water in the engine’s cooling system from freezing. To test the effectiveness of your antifreeze, an antifreeze tester is available for about £5. To use it, unscrew the coolant reservoir cap under the bonnet (ensuring the engine is cold first), lower the tube into the coolant and squeeze the rubber bulb on the end to suck some antifreeze inside the tester.
Thankfully, the rest of the interior is far more commendable. Soft-touch plastics cover the entirety of the dash and, despite the interior looking a tad bland in its monochrome colour scheme, this being a later top-of-the-range V6 CDX model, there's at least plenty of kit to keep you entertained: air conditioning, heated seats, an electric sunroof and a fancy Blaupunkt CD player.
But are these updates enough to keep what is, in effect, an eight-year-old car competitive in an increasingly competitive market?
