GM Specialties was recommended to me by a friend, and I understand why. This was my first time to use GM Specialties, and the first thing I noticed was customers coming who were happy and clearly on good terms with the management--they were clearly repeat customers and everyone was happy. My vehicle has some mysterious symptoms that come and go; GM Specialties kept my vehicle for a week, daily giving it opportunities to manifest its mysterious, periodic symptoms. Well, my vehicle strategically concealed its dark side, but GM Specialties was happy to keep trying, and they were very patient with me. They tried harder and were more patient with the situation than I would have expected.
