Took delivery of my new XE R Sport 2.0 (180) diesel in Italian Racing Red on Friday after a bit of a delay, but its been totally worth it. Extras include panoramic sunroof and HUD (which is really good).
Its good for keeping an eye on your speed without distracting you from driving. The one thing that I have found with the XE is that it is so smooth to drive you really don't realise how fast your driving sometimes, and a quick glance down at the display keeps that in check. You can also choose the items you wish to display on it. It really is just a bit of a gimmick, but its a good one.
