Great write up. Thanks for sharing your experience - you certainly are fortunate to have been chosen for this event. While I don't believe I'll ever buy a 7 series (check back with me in 20 years), that is a beautiful interior. It reminds my of my E39 M5, which is Sterling gray, caramel interior with full leather and alcantara headliner. Of course, I have NONE of the tech in my M5.
