BMW is Spot On
 I have had my 2010 X5 35d for ten days now.  The first thing to note is that BMW has finally got the iDrive system correct.  This version is the best system of this kind I have seen (I have the Toyota and Acura navs also).  The diesel is getting over 31mpg on the highway and 23.5mpg in and around town.  That is on my second tank.  The fit and finish are flawless.  Acceleration is excellent.  The Parking Assist system is extremely good and may be the best feature.  I struggled with what to purchase, I made the right decision.  I even avoided the 2009 X5 knowing the iDrive was going to be improved - WOW did it.
