I have a 2007 XJ diesel as daily driver. It has over 140.000 km on the clock today & apart from having to change the particles filter at 100.000 km, it never broke down once. It is a very frugal car that offers incomparable comfort & silence on long-distance trips. I think I'll keep it till it reaches 300.000 km before changing it... for another big cat, of course!
But of course, my real mistress is Bubbles, no doubt about it!
