Great learning experience
I worked with Brett and Daniel. They both were extremely helpful and informative. Although I did not end up purchasing a vehicle here, they were professional and genuinely wanted to help me find what was best for me. Highly recommend this dealership.
A little expensive, but comfortable, quiet, smooth ride.
A little expensive, but comfortable, quiet, smooth ride. Great performance out of the 6.2L and better than expected fuel economy in the low 20s. Outstanding interior and good looking exterior, especially in the Downpour Metallic color. I don’t have 700 miles on it yet and have owned it for 3 weeks. Therefore, I can’t pass judgement yet on the reliability, but so far I am very satisfied. This replaced an 8 year old Ford F150 that served me quite well with only a couple of issues in the 100,000 plus miles.

Worked with Jayson for a few weeks in finding what I was
Worked with Jayson for a few weeks in finding what I was looking for and waiting for the timing to be perfect. When I went in to the dealership he wasn?t there so Anthony picked up right where we left off and helped me finalize my purchase. Both Jayson and Anthony were fantastic to work with, and I highly recommend either of them!

I absolutely loved the service that my family and I
I absolutely loved the service that my family and I received from Riley. He was very thorough and knowledgeable about all that he spoke to us on and we felt very comfortable with working with him. I HIGHLY recommend anyone who is or will be looking for a new car to visit Southtowne Newnan and work with Riley.
2019 Sierra SLT X31
I purchased a new 2019 SLT with the X1 package. It has the Red Quartz Tintcoat paint. I usually never leave reviews, but honestly this is the most comfortable, nicest loking truck I've owned , and I've ownwd alot of them. The only issues I've had was the brake software was flawed, took it to the dealer on recall and they installed a new software patch, Other then that I love the styling, performance and the interior is very nice. No regrets

Perfectly satisfied with their service.
Perfectly satisfied with their service. I have been using John Thornton and their predecessor dealership at this location for over 25 years. I have never had an issue, and I trust their advice about my service needs and their honesty in recommending when a service is not necessary. Their service department is a factor in why I buy my GM vehicles from them.R
Beautiful Truck
I bought a 2019 GMC Sierra Elevation. I traded in a FULLY loaded 2015 Sierra SLT, that I was really sad to see go, but the Elevation really sold me on styling and ride quality. I lost a couple high end bells and whistles, but the overall performance and look of the truck make up for it big time!

Great Experience overall.
Great Experience overall. Great deal. No pressure. Business done the right way. I am a repeat customer who drove over 2 hours away. Highly recommended.
I have the 1500 double cab with standard bed.
I have the 1500 double cab with standard bed. The reason I have this vehicle is I really like the 6.5 foot bed. The crew cab with same bed is just too long. The things I dislike about this model is that it only comes in the SLE model. For the 2025 that means the external mirrors do NOT have a power fold in and it does not have a seat memory for more that one driver. The power fold in for the mirrors is extremely important to me.

My experience was very fast and simple. I was in an out in less than three hours. Tyler Bell was very professional an easy to work with he did an fantastic job
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.

MR. E. Odoms
it`s my first time using your customer service department so for every thing has been very good.
"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.

Maintenance Appt
Easy in and out with appointment. Greeted by staff with a smile first thing in the morning, which can sometimes be tough. But what a great way to be met. This was for regular service check up, oil change. The lobby in the show room is comfortable and they offer wifi access while waiting.

Gustavo is truly awesome! Thank you
Gustavo is awesome! Very helpful and was able to fit me in to get the rod to my alternator rethreaded and secured. Im very pleased with my experience and will be coming back.
Pleased that I made this purchase
Waiting for the Refreshed 2022 AT4 was well worth it! With all the manufacturing issues today, building and shipping was slow, but understandable. Love the truck and the features! Fit is perfect and quality is #1. Pricing was too high but all vehicles are running this way. You get what you pay for and this truck is perfect! I have owned many trucks and this by far is the best. The latest features are beyond most other makes and GM has thought this truck through from front to rear.

Superman disguised as customer service advisor!
Was in town for my sons lacrosse tournament when our 2022 Equinox broke down. Limped it over to your dealership at 7:30 in the morning to hopefully get an idea what was wrong. I was not expecting any miracles especially without a appointment as a matter of fact I figured I would be stuck there a few days until they could get to it. GET THIS...Bryon Steinke(employee of the month) greeted me and listened to my problem even though he was backed up with customers as far as the eye could see. Took my car and said lets see what we can do. Had me out of there in less than an hour, WAIT...it gets better. He called me Monday morning to see if me and my family got home safely!!!! Who is this guy and where did you find him because there is nobody in customer service like him any more!!! Can't say "thank you" enough times for what he did for us, that is a great employee you have there and you are a great dealership!!
Most expensive auto I've ever owned.
Great performance, hard to clean, everything, I expected. Getting lots of compliments and head turning. Stomping with thee BIG DAWGS!!!! Good gas mileage on highway.

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.
Exceptional truck with one annoying detail.
I truly enjoy every aspect of this vehicle except for the fact that to have my text messages displayed on the screen I have to use a cord and cord my phone into the vehicle. I can Bluetooth phone calls But I cannot get any messages to display without using a cord. For the truck being a 2019 and the price point of it that is absolutely absurd. Other radios that GMCsells has this feature. This truck does not.

Looked at more expensive truck with less options, bought
Looked at more expensive truck with less options, bought the GMC SIERRA AT4 Turbo Diesel 6. I now only put fuel im once a month. And long distance trips are easier due to better fuel economy. One of my best investments ever.

I just want to say that I had a very professional
I just want to say that I had a very professional customer service experience with Ryan Ramdass and wanted to write a review to express my gratitude. Ryan and I had an issue that we had to address and resolve over the phone and he handled it very professional and cautiously. I would recommend Ryan to anyone who is searching for their next Chevrolet! He is a top notch salesman in my book. I his straight forward and to the point and says it like it is and I appreciate that about him and our conversation. Ask for Ryan when you look to purchase your next car he will not let you down.
