My wife, who is disabled and in a wheelchair, has used J&M for years. They have always been honest and fair with her. They have helped her when she got a new car, have picked her up and dropped her off (even though they don't have to) and been super friendly.
I have also been impressed with their skills, professionalism and friendliness. I never hesitate taking a car in to them as I know they will do the job right.
