Prophylacticly changed the spark plugs... but I think they were fine.
Had to change the wheel bearings which was a pain to diag and even more of a struggle to remove in the rust belt... which an EV won't get around.
EV might have saved me from a couple welder repairs on the exhaust and Macgyvering heat shields. And that $10 intake manifold gasket that always fails (2h shadetree job). Transmission ran dry a few times after a metal line rusted out. Bypassed with rubber hose and runs again like a champ.
I love it but will crumble like a cracker in a collision because rust (but still drive because 1zz-fe).
My similarly aged German car is way ahead on factory corrosion protection. Maybe the Japanese manufacturers have caught up but I won't know if/how far behind the Chinese manufacturers are for a decade or two.
