All of the aforementioned parts you've replaced or symptomatic noises you've experienced are typical of this model...it's atypical that all of them would have happened to one vehicle.

At 125K, I would expect the evaporator, radiator and alternator to require replacement. Surprised that the head gasket didn't become an issue considering your luck.

But you've gotten rid of the car, so no more worries. Too bad you spent so much on it, only to have to part ways...
