There is the common joke that you can't trust auto-mechanics, but that doesn't hold true to this mechanic. Jeff is highly professional and he really knows his stuff! If he can't help you, he refers you to someone who can. We have been using him for years and have referred him to several friends who are also satisfied with his work. He is honest and doesn't over-charge. The only drawback might be that he is so popular it is difficult to get in quickly for work!
