I have felt that it is always important to develop a trusting relationship with a mechanic. One that is honest and won't do any more than asked and will tell you first about any issues he may find before attempting to do the work. I have had one mechanic now for thirty years. He is a professional. He is knowledgeable. He is honest. I know that when I take my auto to him, he will take care of it as if it were his. I am not going to put my auto in the hands of someone I don't know who may cause more harm than good.
