TopGear have mentioned the X Type, and have said that it is, like the mondeo that it's based on, it is a nice car with a very nice feel. Indeed they suggested it was a serious challenge to BMW's 5 series in terms of rep car of choice.
Unfortunately, that was in of itself a problem - Jags were up until the X Type a strictly luxury item - strictly upper management stock. The X Type killed all of that stone dead.
$6k is not bad at all. It's a sound a capable car mechanically and Jag's engineers really did improve the internals.
What it isn't however, is a Jag and if that is why you're looking at this, I would strongly urge you to consider looking into collecters clubs or car auctions.
