I have the same build week and my dealer said it is the 3rd week in September. He also said that without any hitches it should be delivered the end of October.
He also told me his 435i demo is at the port and scheduled to ship this week unless the EPA holds it up for new model testing. With any luck it should arrive by the end of the week so I can finally see one and drive it.
Alan, Thats good news. I see your located in New York..Are you following your car status in BMWUSA? At this point Im in the Production stage. Hopefully, It will go into build status in the next few weeks!
Mine had completed production last Sept 2, 2013 and waiting on the port for shipping to US. I ordered on the 1st day it was released for ordering on BMWUSA.COM. That was July 5, 2013. I'll keep you guys updated when I will be seeing it at Greenville, SC for the performance delivery pickup.
