I've had good luck with Millbury Ford in Auburn, MA, when taking my Contour there mechanics-wise. Don't even think of taking a part-Ford there though, they absolutely hated working on my Ford Probe (basically a rebadged Mazda MX6, for those who don't know), told me so, and generally tried screwing me over because of it (incorrect diagnoses, replacing a lock tumbler when only the exterior plastic piece was broken - had to get my dad to talk to the manager about that one!). Parts guys are friendly, service are okay, techs are not but generally get the job done right.
Also, don't go to them for bodywork - Ryan's got one heck of a story about his service there for a simple paint job
