A discreet line with a marker pen could help make sure you get your money’s worth at the garage. If you’ve got basic familiarity with things under the hood of your car, take this precaution before you drop the vehicle off with your mechanic: Put marks on oil filters, alternators and other visible parts that are to be replaced. Then ask for the old parts to be returned to you when you pick up the car. If they’re missing your mark, you may be getting components from another job — and your repair possibly wasn’t done at all.
