I have had 3 Teslas, with 2 more in the family. I am waiting for the new one. I am no more worried about quality etc than I would be for Merc or BMW, and less concerned than I would be for JLR.
We have had no significant issues and where there have been small ones (rattle of a seat belt, moisture in a rear light) they were fixed FOC without any hesitation by friendly service engineers who came to the house.
I will give the new car a good look over as I would any other car but I will not be spending an hour testing every function or measuring every panel gap
