I haven’t used it, but looks like there’s an order spreadsheet above and you can see when orders are getting filled that are similar to yours in the same region.
I’m in Texas and got credit union financing. Tesla order estimate said 4-8 weeks. Got a VIN at 2 weeks from order, which is when they expect you to finalize the financing and have the credit union make the wire transfer. So even though I’m getting the car delivered at week 4 1/2, my financing was completed as soon as I got the VIN. So maybe look at order to VIN info rather than order to delivery dates?
