> Over the years, nearly everything on the vehicle has been replaced or repaired, and Campbell says the only original part is likely the body, and even that has had work done on it.

A modern "ship of theseus" paradox.

It’s more impressive that this man has the fortitude and dedication to keep spare parts, constantly maintain it, and even have back up vehicles for all these years.

If the article mentioned the car had its original engine this entire time. I would have seen it as an anomaly and possibly a good testament to Toyota engineering and need to keep up with maintenance.
