Thanks for taking the time to post a comprehensive review and congratulations on taking delivery!
You'll have to report back on quickness once break-in is done. Speaking of which, is the break-in recommendation the same as with other BMWs? When I had my test drive, the salesperson said there was no recommended break-in period and told me to hammer it. I forgot to look at the usual break-in sticker on the windshield, and who was I to argue?
