The DealerRater system is unfair to John Thornton Buick GMC as they easily rate 10 Stars. Mike and AJ made my experience simple and easy and could not have been more accommodating. They picked me up at AT GMC as they easily rate 10 Stars. Mike and AJ made my experience simple and easy and could not have been more accommodating. They picked me up at ATL and had the truck ready to go. A few minutes of paperwork and a quick technical walk thru and I was on my way. This is how it should be done. Other dealers would be wise to emulate these guys. Thank Mike, AJ, and Andy. You guys are the best! I will be back! More

From the moment I arrived, the atmosphere was warm and welcoming. Luke Darby, my salesman, was incredibly knowledgeable and attentive, making sure I had all the information I needed to make an informed decision. He was professional yet personable, which made the entire process smooth and stress-free. The dealership itself had a great vibe, and I truly felt like a valued customer. More

If I could give this dealership a 0 that score would still be too high for the service I received. I was looking to but sensible preowned vehicle. After agreeing to a $0 price deduction for being a cash still be too high for the service I received. I was looking to but sensible preowned vehicle. After agreeing to a $0 price deduction for being a cash buyer I was told by the Used Car Manager Glenn that he could sell this vehicle to several other people and I could pay the entire balance today even though I was not taking delivery of the car until the scratches were buffed out of the door. The experience of purchasing a car is supposed to be memorable. After being yelled at for no apparent reason I gathered my dignity and took my business back to AutoNation. They didn't even bother to wash the car before they showed it to me! More
