We took our vehicle in because it was running roughly. They said it was only running on 5 of 6 cylinders, it was ok to drive home, and to bring it back in the morning. The said it would cost $750 to repair. I blindly done business with them for over 30 years. We asked a friend of ours in the car business to take a look at what they where going to do. He said a lot of it didn't make sense and he would take a quick look at it. A long story short, it took him about an hour total, only having to replace a coil pack, $47.
