I have my cars serviced at a local independent garage. My Contour started loosing power. I took it to the local independent garage. They found the problem and installed a new coil pack. The cost for diagnosis, parts, and labor were less than $50.
I tried using Ford Service. I have caught them hot rodding my car when I return to pick it up.

They apologize but for them to hot rod my car when I trust them with it is inexcusable. If they would hot rod my car I wonder what else they would do. They are not the kind of people I like to deal with.
