I'm in a similar boat as you ... they originally said that the delivery was 22nd, but that didn't happen and moved to the 27th. Although the DS and the manager said on the 20th that my car has already been build and completed inspection in the factory, they still didn't have the truck to deliver up here in Seattle. They said that my car should be on truck by weekend, but the status page still says "in production", which means that the car is still not in transit .... what's the status of your car in Tesla.com?
My gut feeling is that my car won't be here on the 27th and I'm going to be pissed that I can't get the car before 2018. Especially because based on spreadsheet that there are people who've already got the cars that ordered a long time after mine (Mine is the 100D, so it was promised multiple times to be delivered by end of this year).
