To quote What Car?
'There aren't that many luxury cars available for less than £50,100, but the XJ would still win this award if they were.'

'From its weight-saving all-aluminium construction to its peach of a turbo diesel engine, complete with mounts that virtually eliminate noise and vibration, this is a really brilliant car, and something of a steal at the price. Once you drive it, you can't help but be smitten.'

'One final though: the XJ is currently the cleanest and most fuel-efficient diesel-engined car in its class. If you have any kind of green conscience, there's another good reason to buy it'
