AFAIK, all dealerships are cheats - according to my experience anyway. Last winter an animal had crawled up into my engine (since it was warm once i parked it at home) and chewed up all my spark plug wires.
Ford quotes reapir at $650.
Went to a local auto shop a few blocks from my house and received all repairs and labor for under $200. BTW, the old man thought it'd be a good idea to put some moth balls in the engine bay. Oh yeah, great.
