Maybe it's worse with ICE cars--more parts, many considered wear items, that are difficult to get to to inspect. It could be hard to tell if the seller recently changed the oil and filters after never changing them. Transmission, alternator, etc. could have issues only intermittently.

Should be easy to see HV battery health, charge to 100% and check remaining range reported. Drive unit/other battery issues seem pretty rare and I'm not sure they're correlated with driving behavior, though I could be wrong.
