Aside from the "who knows if they will make '25s" I just recently completed a search for a BW, and only about 25% of the dealers I spoke with would even discuss the option of ordering a car. Of those, absolutely zero percent of them have followed-up, either by confirming my order or asking me for the design code. And this is after several emails and/or phone calls and even one in-person visit.
Also, none of them will tell me how many people are ahead of me on the list. The most transparent - and according to this forum, one of the best dealers - was Sewell in TX, not too far from AZ, and they said 18-24 months. That may mean that you'll never get it.
So, my advice: don't wait.
