I don't mean to thread-jack, but might as well keep it all in the same thread...
So I went to the VIP thing tonight. Autocross is in M3/M4 except they only let you do one lap. Since you don't really know the track that well, its hard to go all out (not to say I didn't try). They have other cars including an i8 available for test drives. The i8 was probably just a ride along. I didn't do it... line was too long. I may go back wednesday morning for my reserved spot in the autox. The winner at this event was the food. Chef Josh Capon held a cooking demonstration, and they served a 3 course mini-meal in addition to an "appetizer" bar.
I left the event stuffed and ready for bed. All in all... another great experience compliments of BMW. They're really good at hosting these customer loyalty events.
