Love my seven!
 I've owned this car for 18 months.  I LOVE it.  It drives like a dream and I have had no problems at all.  I have the all-way adjustable seats with a/c, heating and a massage.  They are the 2nd most comfortable seats I've ever driven in (next to a Toyota Land Cruiser, believe it or not).  The iDrive gets loads of bad press, but it's fine.  I even like it.  If you are not totally tech-averse, you will not have any trouble with it.  Contrary to what's written, the most frequently used controls are still available on knobs on the dash.  Sound system is great, but the two CD players (one changer, one in-dash single) is perhaps a bit of overkill.
