I don't know where you are from, but here (country in Europe) no-one does that. If they buy it new, pretty sure most things are covered by warranty and even small user fault issues brands tend to fix.

I bought a 120k Porsche and didn't go and get it inspected. If I had any kind of problem with the car, I would just call ahead to secure a time slot and they would look over it/try to fix it. Once they diassembled the entire back seat system because of a rattling issue. Found out it was a metal ball from my kid's toy that went through the seatbelt hole and got under the seat. Took them a few hours to do so. Cost? zero. They replaced small parts for free also. Needed a bit of oil? not even a call, just stop by the shop and someone would do it in 10 minutes.

The fact that are documented cases, over and over again of bad QC on Tesla, and they refuse to fix it or tell the buyer of a brand new car it will take months to fix because they don't have the parts is just shitty behaviour, which I understand may fly in the USA, but in Europe they are running into troubles (already are with marketing issues re auto pilot and even Musk 'get back into the office' memos and shit)
