So I just purchased a used M3. I'm still currently waiting for the previous owner's bank to release the title and for him to mail it to me. It's in another state, so when it's time to drive it back, I'll have to use Superchargers on the way home. If possible I'm going to try and get the Tesla account transferred into my name, but I've heard sometimes that can take a few days. If that's the case I'll have to drive it home without the account. I take it that supercharging is paid for through the app, but on Tesla's website I noticed it says you can add payment through the car's screen. Is this a possibility? Just wanting to make sure I have a way to charge on the way home.
