I see a lot of unanswered questions here.
You need get approved by BMWFS first, then you have officially locked in for the promotion and rates for that month for 90 days in CA and 60 days else where.
Anyone can order a car, and not everyone will get approved.
If the BMW you desired is going to made in Germany, then it's a good idea to get approved first and have your advisor start looking for an allocation for you, and get your car ordered asap.
I got my allocation from Justin, and I was approved literally within minutes after I sent him my BMWFS credit app via e-mail.
