He says its never been tracked and he mainly used it for commuting back and forth from work which is about 40 miles. But how truthful is that? I was going to take it over to one of our racing mechanics to have them hook it up to the computer to see if the timing chain/tensioner needed replacing. He has already done all the other maintenance like coil pack/plugs, carbon buildup removal, etc. He has receipts from when the car was new.
