I don’t know why people list transmission and engine full replacement costs as a maintenance cost of an ICE. The whole point of maintenance is that you don’t end up doing anything like that.

Is it possible to blow up a maintained engine? Of course, ask anyone who has owned a WRX :)

But if you are driving a normal (IE not “performance”) car and you aren’t just thrashing it, then I would expect multiple 100k out of an ICE.

That’s said: 5k in maintenance over 90k doesn’t seem insane, especially given the great deal they got on their emergency replacement tires :-O
