    Compression on a high mileage motor

    I am looking at a high mileage wrx at the moment (125,xxx miles). There are some little things i will take care of but i was worried about the condition of the motor. I took the wrx into a shop and they did compression test on the motor and the result was around 125psi for all 4 cylinders. Is that normal? Or is that a bit low. Any feedback would be awesome. Thanks

    Those are solid readings for a motor with that many miles on it.
