I would change them, but the engine has a faint knocking sound between 1600-1900 rpms. It has not gotten any worse in the 10K miles I have owned it, but I am concerned that my engine is simply worn out and really do not want to put $$$$ into the engine if it is knocking anyway. I have been told that the knock could be a worn camshaft on the passenger side of the engine.

Transmission wise, body wise and interior wise, I know this car would easily last another 100K. Body rust free, interior in excellent conditions and everything still works (save for the A/C).
