Greasy hands and oily intentions? Have you ever caught your mechanic lying about something that needed to be done or that was done to your vehicle? If so, tell us about it.
When you have found an honest mechanic you have found a gem but until then the best way to verify what your mechanic is saying is to take your car to other mechanics to get their opinion and see which one sounds the most 'honest'. Getting referrals from others is also best because they would have already done work on their car.
