Check my other post, but I made this change this week. Previous car was XF 4.2 litre. Wonderful car, but very expensive to run. Three days with my F Sport and apart from sheer accelleration ( hardly ever indulged in in the Jag as it reduces already poor MPG even further ) the Lexus is at least as good as the Jag. The XF came with a lot of kit, but the F Sport has voice command, fogs, DAB radio, heated and cooled seats ( once you opt for leather ) front parking sensors and other kit that I had to pay extra for even on the 4.2 XF. As our Amercian friends say, what's not to like?
