I've had bad experience with any mechanic. Ford or not. I've had non SVT rotors put on. When I had my water pump fixed. Hah! It leaked two weeks later. I've had a mechanic switch my brand new plugs and wires saying that was the cause of my misfire. I've had guys look at my car and refuse to do anything because of all the modifacations I have done. Like my battery being in the trunk has anything to do with why my starter wouldn't turn. My sugestion is if you know how to fix somthing, do it. IF you don't. I'd still try to do it. Not once has any mechanic done anything to my liking on my contour.
