I have never purchased a car from this dealership but have experience some pretty slow service here in the past in the Service Department. I would definitely recommend you make an appointment even if you are going in for an oil change as it can take quite a while to get through.
That said, I recently had a further issue after an oil change (damage caused by a service rep, though definitely an honest mistake) that I had to escalate up to management. Coleman, the president, responded to me late on a Friday and e-mailed with me back and forth past midnight, talking about the issue and showing great empathy for my situation. While the front-end reps in Service did not want to take responsibility (I understand them wanting to protect their business), Coleman was great in listening to my story and working towards a resolution. He put me in touch with Chris, the Service Manager, who was prompt and friendly. I brought my car back in for him to take a look at and he quickly agreed to take care of the issue, and was great with communication to get it all resolved. I was certainly upset when this all began but Coleman and Chris were excellent at service recovery and really helped to put me at ease. I am happy to have the broken piece replaced and feel comfortable continuing to do business with Acton Dodge
