That would probably be Tesla? I suppose it depends on your definition of repair-ability. Telsa has a high degree of parts compatibility and seems able to keep even the older 2012 era Model S repaired.

There are a lot of high mileage Teslas out there. Most of Tesla's negative reputation seems to be people complaining about fit and finish (paint, panel gaps). The actual mechanical reliability seems to be quite higher than a normal ICE car. However EVs are still pretty new so long term data is still being collected.
