My OD also 1/26 (evening so they called it 1/27 (Tucson)
Initial EDD: Feb-Mar, then updated to 3/16-3/31 a few days later and has stayed there since.
No VIN
Seeing a bunch of folks who ordered around 1/15-1/17 getting VIN's this week. Really hoping mine doesn't get pushed out as some have into May as we leave AZ for ME in May and that would require cancelling my order and "trying" to find a hybrid or something somewhere on a dealer lot which would really suck! I sold our vehicle last week since Tesla's trade offer sucked so bad ($9K more selling privately). Will just have to do grocery shopping a little more often on my motorcycle!
What number did you call to speak with a live person? As far as tax, most states would waive the sales tax if you show residency in another state. It all comes down to where you register it... they're gonna get you there for sales tax. Sometimes you have to file a waiver of sorts in the other state that says you'll pay sales tax in your home state.
