For over 35 years, once the dealer warranty has expired, I have taken all of my family's autos only to Preferred for service. I have always trusted them to tell me what was needed, especially for safety, when it was needed, and to give me the actual costs involved, and I have never found their charges to be out of line with anyone else's in the Washington, DC area. Their service is first rate and they never fail to follow up to make sure everything is OK. I trust their work implicitly, and will continue to use them, as will all of my family. I would recommend them to anyone, and often do!
