I'm also one of those impatient 2010 X5d buyers waiting for build and delivery...so I will break the news to ya
1. Building of the 2010 X5's start Oct 9th in Spartanburg (the 2010 X5 M has already started production and deliveries)
2. The earliest delivery date will be in November.
So, sorry - we are going to have to wait for some pics since last I heard...they haven't converted the plant to start cranking out the 2010's.
Maybe the recent 2009's that have been build might have the new iDrive? Unsure about this though.
EDIT: WOW, thought I was the first one to respond...damn I'm slow.
