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
