I just received some car mats from Fitmycar which exactly fit the stock mat hooks in my Jaguar X Type. They are of good quality, shape and fit as good as OEM, fit perfectly and are reasonably priced - check em out.

I haven't got the foggiest, how to find anything for Jaguar (or anything at all for that matter) on above ling - but does not matter:

I know, how to get perfect custom made mats - at least, where to get it in the town, where I live, but maybe you can find a similar deal, wherever you live:

I went to a local carpet shop. I found some matching carpet-leftovers for mats for my S-Type there. I gave them the old & worn mats, and they made perfect custom copies for me for very little money with all the stitching around the outer boarder.

 

That's really good. But for those people who can't go the custom made route I recommend fitmycar. One of the cool things is the website has a configurator where you can customise the border and stitching colours.
