I did an earlier review, and I have to say I was in error. I was very frustrated with problems with my car, and wrote the review before we had everything worked out. I had a P0016 error, and most likely something to do with timing. When they explained it to me, it was very clear, and will take more diagnostic work to get to the root of the problem. I will definitely bring the car back, when I am able to get the next steps done. They did a great job. It is hard working with a frustrated customer, and they did well. If you happened to read my earlier review, ignore it. It was not valid or accurate. 10 out of 5!
