I have never had anything but trouble with Andy's. They have continually misdiagnosed problems or done work that I did not ask them to do. There have been sometimes that they screwed up work I did ask them to do. And there have been several times that they have charged me double what they quoted me. If you are looking for a good mechanic in Watertown, go to Mel's Garage. They are amazing. But steer clear of Andy's.
