Jack Williams has a nasty habit of trying to sell you things that you don't need. Since moving to the area, I have tried to find a reputable mechanic (which is hard). My employer offers a discount for service at their auto center, so I decided to give it a shot. I don't know if these guys are working off of a commission, or if their jobs are threatened without aggressive upselling - but something certainly isn't right.
I've had two cars since moving here, and every time I go there they find something wrong with my car. They have sold me on ball joints and new brakes (because they were "supposedly" necessary to pass inspection), and they have tried to push unnecessary repairs on me ever since.
Now, I will admit that I'm no expert on cars - however I know enough. I can tell when brakes, rotors, and ball joints, control arms and rods need to be replaced. Jack Williams (at least the one in Dallas) is a major gyp, and I want to warn people to stay away from this place at all costs. I'm looking forward to the new Kost, because there aren't many alternatives in the Back Mountain Area.
