But your vehicle went to status 150 - which basically means "No more changes". While they call it "Production Started", nothing has really happened other than BMW is lining up all the parts to coincide with production. My car entered "Production" aka status 150 on the 24th of August. It is a week 36 car due to be done on September 8th. It will next go to the body shop (151) and get its serial# assigned (and yes, I already have a VIN), then the paint shop (152), then the Entry assembly (153), then Assembly (154) and I forget the rest.
Long story short - status 150 sucks. The car is still a week or two away from being made and you can't change your mind on anything (like damn, should I be thinking BSM or stay with LBB)
