I live in Jacksonville my friend, and have a MSLR on order since June. This is Tesla #6 for me, so I’m quite used to the craziness that is “pre delivery waiting“. Best advice I can give you is the same everyone else is likely too, once you have a VIN your date will likely lock in. Mine has changed about 9 times from October to March and currently is sitting at Feb2- Mar2. Typically, east coast cars are delivered in the second month of each quarter but that often does have variances. I believe (someone correct me if im wrong) that Tesla builds the cars in batches of “like” cars. For example this batch may be all black/cream LR w/19s. So likely you will get a VIN based on your configuration, not your order date. Hope this helps!
