"In couple weeks I got notified that my refund was approved, and I got contacted by another guy, who suddenly suggested me to get vehicle rebuilt. Of course I agreed to that generous offer saying I’d love to have the same vehicle."
What?
What?
tldr: The author was excited about getting a brand-new Tesla, but a lot cheaper than a brand-new Tesla, which turned out to be false.
I believe the author meant that Tesla would build a new one to the original specifications. This is probably reasonable, the majority of Teslas probably don't have terrible problems or we'd hear more about them, so throw the old one in the river and get a new one isn't a bad idea.
Perhaps it is the EV equivalent of "have you tried turning it off and on again"
Given that Tesla thinks there is nothing wrong with the car, the only way I see that conversation working is if the car is returned unaltered.
2. ...which Tesla had been unable to remedy, to the extent that the customer has requested a new vehicle or a refund...
3. ...but the customer is eager for the chance to get the same vehicle back.
I'm afraid I don't understand the thinking.
