This is a concern for me not only for the Tesla but for the new Chinese manufacturers. When I've talked to owners of these cars (in other countries), the consensus seems to be "you use it for 5 years and then throw it away". Not because the car has poor build quality, but because there aren't local mechanics that can service it, it's impossible to find documentation such as torque specs and service procedures for anything but trivial stuff you'd find in an owner's manual, and it is very hard to find parts.

It seems like an incredible waste to throw away a car after 5 years.

A big part of what I look for in a car is a long lasting manufacturer that publishes to end users technical and repair information, including part numbers and procedures, together with a healthy third party part supplier ecosystem and independent repair infrastructure.

That doesn't mean that information needs to be available for free or that the parts themselves are cheap -- Volvo parts are not cheap -- but they are available and the information, engine specifications, repair manuals and workshop manuals are available.

If you don't have that, I'm not interested in buying the car. A car is far too expensive to treat as a disposable consumer good. I'm worried that more and more, manufacturers are locking down their systems, putting information behind paywalls where you can't make your own backup copy, and doing things like adding DRM to their parts to prevent indy shops from working on them.
