An electrical issues in a car can be a time consuming and difficult issue to diagnose. John and his team (Greg and the mechanics) were determined and extremely fair $ wise finding the cause of the issue in our Jeep Grand Cherokee and fixing it. My wife was very upset when we discovered the malfunction in that she was in an accident two days prior, that totaled her primary car (Lexus). The Jeep, which was used primarily in the winter, became of critical importance for her to get to work until we get a replacement vehicle. Anyway, the South Park team were very understanding, professional and diligently fixed the car quickly. They cared and did a great job. Thanks John!
