You didn't buy a Jaguar XK because you wanted to fade into the background. Jaguar's grand tourer features the kind of sleek, two-door body that turns people into automobile enthusiasts, and as powerful an engine as the British automaker can produce. The XK takes a backseat to nobody, and outfitting it with anything less than custom-fitting parts would be a shame. Lucky for you, there is a list of just such parts on the page below. Treat your Jaguar XK the way that it deserves to be treated, as though it were the best. In many ways, that's exactly what it is.
