Third time was the charm, though we weren't initially convinced it was going to happen at all.
We received a call last Friday confirming that the car was at the delivery center and had been inspected, so it was guaranteed for today's 3pm delivery. We'd receive a call an hour or two beforehand, they said. Great! Nice change from the 24-hour or less notice of cancellations the last two times. Then 3pm came and went. At 3:30pm we called the delivery center – which went to voicemail. The voicemail said to press zero to transfer to the national delivery center, which resulted in a recorded message saying the extension in question didn't exist. Not impressed. My wife called the service center, and they said the car was there but it hadn't been prepped and there was no way it was getting delivered today. Needless to say, she was beyond unimpressed at this and stated clearly that she was inclined to demand a refund. They put her on hold, and ten minutes into her hold time we received another call indicating the car would be on its way momentarily.
From there, things went much more smoothly. The car looks amazing, and we can't wait to put it through its paces over the next few days. The process was exhausting and infuriating, but I'm sure that impression will fade with time. Rapid growth is hell on a company, but Tesla really needs to get their act together on the delivery side of things.
