Any car used as a TAXI will outlast the equivalent privately driven car.
... Because most of the mileage is done with a warmed up engine.
When I first saw a Prius taxi locally I knew they must be good cars because the Taxi companies do their home work before buying any new car.
Toyota doesn't make junk. I just wish they would build a car that I would find desirable. Something with character.
Something like this but not 4x4
