My 2006 MDX has been serviced by Master Mechanic for several years and they have always told me that they stand behind their work. Well, they have proven that to me when my MDX was having problems they checked it over and determined that the problem was something related to work they had performed some time before. They did extensive work to get my car running better than it has for quite some time and I am grateful that they didn't charge me a thing for all of that warranty work! Thanks Master Mechanic, I remain a satisfied customer!!
