Group One has done the work on my 325i for a while now. Bart and staff do a very good job, explain things that are needed, including those coming in the future, which is the MAIN reason I go to them. Only small critique I had on last visit was, when checking for air bag light. Was first explained that the testing machine would not have to be used, but it was without first letting me know. This entailed a charge, which I understand. But in future, would like to know if estimated plan is changed. Other than that, always good service from Group One Motorwerks, and I would recommend!
