I bought a 3.0D 07 plate 2 weeks ago and couldn't be happier. The tyre are probably needing replace in a couple of Months and the idrive has stuck a couple of times but it's still under warranty so BMW are going to upgrade it for me. Said it would take up to 6 hours!
All in all though, in my opinion it is a much better vehicle than the older versions which were superb anyway.
