Let me give you one in NH, in case any other Granite Staters or Northern Taxachusetts drivers are interested: JJM Fleet Service, Salem, NH- 603-898-7993. Ask for Jeff or Gus. Good honest guys that know diesel engines in general very well and have done great work on my car at reasonable rates. They stand behiind thier work, and I don't mean " as far behind it as they can get...". I've used a local dealer to make punch lists, like when I bought the car and wanted to get it right, and have JJM do the work. Now it's the only place I take it.
