They are they worst. if i could I would give a negative star. They will lie deceive and do whatever they can to sell you a car. No matter the cost to you.I never felt s if i could I would give a negative star. They will lie deceive and do whatever they can to sell you a car. No matter the cost to you.I never felt so ripped off in my life bought a 2023 rt charger and Was told my warranty was still good for about 40000 miles. So when the car started making a funny noise took it to the dealer and guess what? It was modified and I have no warranty. They clearly knew this and never mentioned it So please take my advice and do not go to john thornton More

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
