To the OP:
Here's my view as a Tesla shopper in August 2019. I really wanted to get a Tesla. I had spreadsheets calculating out my savings. I had a bid from an electrician to install a charger. I was pretty far down the Tesla road. So this is my real opinion. I'm not a troll looking for trouble. I'm a person who understands the worry that you are feeling. You
really want that car, but you're starting to get worried about customer service. I get it.
Right now is a bad time to get a Tesla. It may be better in 3 months or a year. I don't know. But I do know this:
right now, service centers are swamped with cars. Customer service is also swamped. If you order a car, you can't get a concrete answer as to when you will get it. If you get in an accident, you may have to wait for months for parts.
There are also some questions about build quality. There have been a lot of problems with paint and electrical systems.. I don't know whether it is with 1% of the cars or 10%. I know a Chinese company bought 278 Teslas a few months back, and claimed that more than
20% of the 278 cars it purchased experienced "electro-mechanical failures."
I looked at some other EVs, and was really interested in the Hyundai Kona, but the dealer was asking $5,000 over sticker. So I leased an ICE vehicle for 3 years. I figure by then, the EV market will look a lot different. This month, we have seen releases of two more EVS at opposite ends of the spectrum -- VW and Mercedes. So in 3 years, I figure there will be about 25-75 EVS with a range of over 250 miles. They will probably be cheaper too.
But right now, you are talking about handing over a small fortune to a company that won't answer the phones.
So here's my honest advice to the OP: cancel it and wait a few months. If Tesla starts opening a lot of service centers, and answering phones by then, get the Model X. If not, wait another three months. Or get a VW or Mercedes or Hyundai or Bolt.
