I trust Group One to do the right thing the first time. I would not hesitate to recommend their service to anyone. If I did not have a service agreement where I purchased my Smart, I would be going to Group One for all my auto service. Actually, I am looking forward to my service contract expiring so I can have all my service done at Group One. I have total confidence in them. Everyone who works their is very knowledgeable and a pleasure to deal with.
