I have always used Bommarito in Hazelwood for my 05. In fact I have an appointment on 10/11 for an oil change and brake/clutch fluid change. Tim is the only tech to work on my car.
That said, the new GT has to go to Dave Sinclair Ford since they are the only official GT service center in the area and have Steve the certified tech. Gary uses them as well. I have been very pleased so far. They are much closer to you. Give me a call if you want.
Also, the service areas are so busy it takes weeks to get an appointment.
