Ok, looks like I spoke too soon. My Vehicle Inquiry Report from the dealer does NOT list 493. However, when I looked up my VIN on
www.bimmer.work it does list "493 Storage Compartment Package / Ablagenpaket". So I guess I have it. FWIW, it's an M Sport with (obviously) Sport Seats.
Build date was 2015-11-28. Welt delivery next week, woot!
