There is. It's called "going to the mechanic to check if the car is in a condition as advertised".

Mileage is a fairly reliable measure for the expected state of the engine/drivetrain of the car. The parts that, if worn out, usually get the car scrapped, because replacing them would be as expensive as buying a working car.

I would love to hear from someone who'd replace a broken driveshaft or a wrecked engine on a Toyota Corolla.
