Interesting, looking at the Model 3 Order Tracker sorted by VIN, there's a chunk of cars ranging from 601290 to 602785 that seem to all be P3D-. That's approximately 1500 vehicles. Of the available entries, 20/57 (35%) so far have been delivered. Of delivered vehicles, 77% have been to CA (52% of all entries are CA orders). 72% of all entries indicate that a delivery has been made or scheduled based on the "configuration to delivery" data.
There definitely are errors in the spreadsheet, though. My entry says "delivered" even though I have not yet received a delivery date, and my car was still pre-production as of yesterday.
