I would like to share my experience here and dealing with
I would like to share my experience here and dealing with Travis over the last week and a half. My wife and I contacted him about a 2017 Audi R8 on a Saturday that we were in Atlanta for a Braves game. I told him we were interested in looking at the car for potential purchase. It was last minute, but he told me "sure come on, the car is here, and you can check it out". We drove to see him and when we got there, he greeted us and introduced himself and showed the car to us. He offered to take me for a ride to check it out and was very pleasant to deal with. After we were done, he told me he would take care of getting the financing done and would try to get me the best deal possible. After staying in contact with him about the car for about a week, he delivered on his word of getting the financing done. My wife and I went back and forth on whether we wanted to spend the money or not. Even after being indecisive about the purchase, he stayed patient with us and wasn't pushy. So, we finally told him we would come get the car and sign the paperwork. Once we arrived, I asked him if we could check the car over really good one last time before signing. He was cool with it and because we were already approved and had insurance on it, he said, "here take it out for a spin and let your wife see what it's like and when you are done come back and let's talk." We really enjoyed the car and told him when we got back that we wanted to discuss everything over lunch and would give him the final answer after eating. Ater talking, there was just a few issues that were concerning to me about going forward with the purchase. To be honest, they may not have been big deals but for us purchasing a car like this for the first time we figured it would be best to wait until we find one that just made everything feel right. He understood and even offered to take care of the issues, but my wife and I just still weren't there on the car. As an owner of a European car repair shop there was just a few things that made me not want to go through with it. The R8 was beautiful and felt solid and like I said it was small things that probably wasn't a big deal, but they changed my mind. We didn't go through with the purchase, but it had nothing to do with Travis and how he conducted business. It was just mainly me being nitpicky on things. I never asked him to take care of the issues at all. He offered to do it. So, I must say coming from a business owner myself and dealing with customers on cars, I appreciate that a lot. He was very professional and easy to talk to. I would still consider purchasing an R8 from him if he were to get anymore that just makes my wife and I say, "yes this is the one for sure". I understand that everyone is going to have a different opinion about a business and their experience, and you can't please everyone all the time. I deal with it at my shop from time to time. I'm basing my review off of my personal experience here. Travis, if you read this man, we genuinely appreciate your time, professionalism and integrity. Thank you for being patient with us and I'm sorry we couldn't make a deal at the time.
This truck has a jerk when changing gears sometimes.

Had a great experience
Ollie was amazing he took care of my needs and help me to buy my dream car for my family. I will continue to do business with him and bring business to there company 5 stars all around great job .
Great truck!
I bought my 2020 with 36k miles a couple of years ago and I now have 60k miles of trouble free very enjoyable driving. It was expensive, but worth every penny. The ride is so quiet and comfortable my wife and I prefer traveling in it instead of our 2018 Acura MDX which we also love. The 5.3 V8 has plenty of power and towing ability. The multi-function tail gate is genius, I hope to never be without one again. We so enjoy all the bells and whistles, especially the wireless phone charger. So glad I bought this truck!

“I had an exceptional experience working with Laquacia
“I had an exceptional experience working with Laquacia McCullen, she was professional, knowledgeable, and genuinely dedicated to helping me find the perfect vehicle. She took the time to listen to my needs, answered all my questions with patience, and provided outstanding customer service throughout the entire process. I never felt pressured, and their transparency made me feel confident while searching for my next set of wheels.I highly recommend Laquacia Mccullen to anyone looking for a smooth and enjoyable car-buying experience!”
Like the truck but also disappointed
Got the duramax diesel and getting 24 city and 32 highway is very good. Truck drives nice and is very comfortable. My 2 issues with this truck is the backup camera at night is useless (very dark) and interior lighting is not very good. You would have thought a 78k truck would have footwell lights, but it doesn’t.

2022 GMC Sierra SLT 3.0 Duramax
My 2022 GMC Sierra 3.0 Duramax pickup truck is a good truck. I work on a farm and I also drive an hour to see my girlfriend. For the farm, it has excellent towing capability and for the hour long drive to go see my girlfriend, depending on the weather for traveling, I can get up to 35 miles to the gallon!

Great dealership!
I have purchased a number of vehicles from John Thornton Chevrolet and one from John Thornton Cadillac/GMC and have had great experiences in every case. They are the only dealership I use for service for my Georgia based cars.
Nicest, best performing truck I've ever owned
My truck has a great appearance, inside and out. It is a pleasure to drive; and rides and performs great. It is the best truck I've ever owned.

"THE" GMC Truck!
I have a 2023 GMC Sierra 1500 Denali with the 3.0 Diesel engine. I have 20,000 miles on it at the time of writing this. Never owned a diesel before and now i don't think i will own another one without it. I LOVE the engine in this truck. Only complaint would be that it likes DEF fluid while towing so pick up some extra DEF before you head out to tow something. Put about 8K miles on it this summer without adding any DEF fluid. seems to use a little more in the winter or when towing. Very quiet for a deisel and the fuel economy is awesome. Driving 70 mph down the freeway this truck gets about 30mpg, Drive 55mph on regular highways and this truck gets almost 40mpg. All around driving for me is about 26mpg. I used to fill up twice a week with my gas motor and now only once a week. Wireless Apple Carplay works great and the voice texting and mapping is a big plus. I also have the new SuperCruise feature which is awesome. Get on the freeway and set the supercruise on and the truck drives itself until i get to my exit (about 28 miles from home to work). Bose stereo is out of this world and all the storage is great to. I have a swingout bed toolbox, aluminum roll up tonneau cover, Lighted black GMC front emblem, Gloss Black 22" wheels, All Black decals and my dual exhaust bezels are black as well. I rotate the tires and change the oil every 5,000 miles. Couldn't ask for a better truck. Might get the ultimate next time as that has the messaging seats which i kinda wish I had.
