After several false starts with my IDA, I was scheduled for a 2:15 delivery on 8/16. I don't feel bad about posting my IDA's contact information because as of this evening, that number no longer rings into voicemail. I assume they have been let go from Tesla. I arrived at 2:00. Things went downhill rapidly. The associate running "check-in" was very nice, but told me that I was not on the list for delivery, and my car was not on-site and needed to be cleaned & detailed. They apologized for what they described as an "error in the backend systems". They said my car would be ready in 60-90 minutes, so I pulled up a book on my iPhone and started reading. At 3:45, I met my host. She was very pleasant and nice. We started filling out paperwork. Around 4:20 my car was "done with detailing and ready". We head out to the parking lot to find it. I wish I had taken pictures. The car had not been fully washed. There were sections of the car with thick dust on them. Handprints all over the car. Excess wax all over the car. I asked that they take it in back and re-clean it. A female associate who identified herself with being from the garage tried to claim "Oh that's just street dust. The car has been sitting here all day." She said I was lying when I claimed the car had just been detailed. So either the Tesla garage rep was lying, or the manager was lying. I left the Tesla showroom at this point because I was furious. The guys working in the cleaning/detailing department obviously did not care about the quality of work they were performing. There's no way that the guys did not see the dust caked parts of the car when they were waxing it. Around 5:00 my car came back, and it was in good shape. Veronica started showing me how things work on the car, and she left me in the car to finish up the paperwork. She returns with the manager Alex who informs me that they have changed they way they handle funding with USAA. On 8/8, Tesla stopped accepting USAA Dealer Funding Requests, and started requiring check-in-hand (or photo & tracking number) before car is sold. I spoke with another car buyer who was also financing through USAA. His IDA sent him a PDF that covered all the steps necessary for funding the purchase through USAA. My ISA never sent me that document, despite being informed multiple times that I was financing with USAA. Without that document, how could I have known what to do? So after spending 5 hours at the Tesla delivery center, I finally had to ask them to call me a Lyft to get home without the car. I'm upset that Tesla was not willing to cover their own mistakes. A member of the Tesla team messed up repeatedly. I've asked multiple times to speak to that person’s supervisor, but have never gotten a call from that person. This was supposed to be an awesome day. Most people I saw at the delivery center were happy and smiling. Not me. Not by a long shot. Hey Tesla - ever heard the saying "You're only as strong as your weakest link?" You make amazing cars, but you get a F for the delivery process.
