Are you kidding me? I have a strong suspicion that you are getting screwed.
Buying a car sight unseen is a huge risk. And now you are getting jerked around with the paperwork? They are not returning your calls? Don’t be surprised when a defective car shows up, if it shows up, leaving you disappointed.
You need to immediately cancel the deal and get your money back. If you don’t feel like that’s a possibility then immediately travel in person to that dealership and complete the deal that day or get your money back and walk away learning a valuable lesson.
I wish the best for you. But what you’ve said leads me to think you are getting screwed.
Its a real dealership. Full online presence. Listed by BMW as one of their official dealers. Registered on cars.com. Etc etc.
