It used to be that almost any tech could fix any car these days, not so much. Your Cadillac is unique, and its complex design, systems, and engineering mean that only a few people should be able to work on it. Even though you could take your Cadillac to a private mechanic, the fix they do might not be right because they don’t know much about your car. Techs working in places such as Radley Cadillac have all finished training with Cadillac.
