Until Tesla allows other shops to do repairs, those swastikars will never be economical even if you ignore the Nazi part

Everything on them can be fixed by a regular mechanic, and Tesla isn't stopping it (at least not in Europe). People are getting 3rd party special shops to fix HV batteries and motors on old model S without any issues. Brakes, suspension, steering, LV electrical (windows, lights, handles etc.), AC can be fixed by anyone without issues. And aside from body parts and a few specialty components (their "octovalve" comes to mind), it's mostly standard auto components that can be bought from 3rd party manufacturers without giving Tesla any money.

Edit: a model 3/Y door handle is around $100, of course still expensive but also far below your $1000 example, and on par with an original handle for my old ass Peugeot 308.
