Florida just got a huge shipment. some of mine my friends in Florida saw the truck loads. now it may take some time to get them unloaded and prepped. but I can almost bet that your car is there. for example, my delivery window is not 12/26-12/31 for yours to be today thru the 20th its already there.
I'd think that once a VIN is assigned, the newer, more granular estimate becomes more accurate, barring any unforeseen circumstances (delays in transportation/damage to the car).
Ah okay, that makes sense. Hope it's here
