I bought a Jaguar 2.0d x-type estate on a 05 plate 2 years ago.
I have no issues with the cars aesthetics, the leather seats are very nice, the extras such as rear park assist and electric / heated seats are all fine. My issue lies in the reliability of the car. I have only ever got 40mpg and we don't drive the car fast, so I'm not sure where the 48 comes from that Jag refer to! Also, the whole turbo needed replacing at a cost of £2000! Not really something you would expect on a 4 year old car with a hefty price tag. I've since found out that Ford have been fitting the Jags with dodgy 2003 spec Modeo diesal engines, which are prone to Turbo problems. Again, not something you would expect with the Jag brand. They really are ruining the Jag image and brand name! All in all, I wouldn't recommend a Jag, my old Seat Ibiza was much cheaper, more frugal and more reliable with pretty much all the same extras (exc the leather)!

Not the most reliable car I've ever owned. Airbags failed due to wire rubbing against front bumper mountings. Has a flat spot between 3250rpm and 4000rpm that is often so noticeable you would think you'd lifted your foot off the accelerator. Dealer says there is nothing wrong with it. Then takes another £120 off me. This week it has started dropping into 'limp home' mode. Engine is still sweet as a nut it just appears to be all the other stuff around it that falters. Oh and yes I do have rust under the boot number plate recess like every other Jag. Did I mention that it eats tyres as well? about 10,000 to a front set.
