Funny, my wife dropped off our Model S at Scottsdale Monday night, too. Tim just called me and said they wouldn't get to it until Wednesday. While I had Tim on the phone I asked about getting my Roadster in for annual service and it's looking like the week of 6/20 for that.
I think there are lots of new owners and Scottsdale SC seems to be busting at the seams. Tempe is sorely needed and let's be honest. They do no have the infrastructure locally yet for the Model III service, but they'll get there - eventually. I was actually around in the early days at the somewhat secretive hangar, but those seems to be distant memory. There will be growing pains unfortunately.
A little off topic - I don't know about anyone else, but the A/C in our Model S was overwhelmed with the 116-117 highs over the weekend. It was literally blowing hot air during the heat of the day, but able to cool at night. Unfortunately, I drove 50 miles in the Model S with no A/C Saturday afternoon and on Monday, my wife drove from work to the Scottsdale SC with no A/C. It was actually good timing for us to have annual service. I know it's hot, but this car needs to be able to tolerate this heat.
We're setup pretty well with the loaner, so no complaints on our end.
