I looked at a 1978 300CD, non-turbo. The car has 62K original miles. The owner's mechanic claims that a cam and rockers will need to be done soon, no time given. He states that there is scoring on the cam. He saw this when he adjusted the valves. He also states that this is caused from lack of oil changes and that the car has sat. I now question the validity of the mileage. The car is clean, doesn't seem to have been tampered. Any thoughts??
