Finally! I received an email at 5pm today from my delivery specialist: my Sig Red S#187, VIN118 is on the truck and headed this way!
Minor bummer: if I weren't out of town this weekend I'd have it Saturday or Sunday, but I'll just have to wait until Monday, I guess.
In the event, Tesla delivered S187 and put it in my garage today, while I was in Albuquerque. My delivery specialist will drop by after I get home tomorrow (yes, on a Sunday evening) to do the paperwork and walkthrough and give me my temporary registration. How's that for customer service?
