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
So far so good!
So far so good! This truck is the nicest truck I have ever driven. The stance, ride comfort and options are top notch. I went from a 2023 High Country that was having drive train issues but had all the creature comforts that you would expect in a top of the line truck. With the lack of confidence in that particular models 10 speed transmission issues, it became necessary to reestablish my confidence in my General Motors product.

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 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.

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.

Global Imports has been great for me over the years
Global Imports has been great for me over the years because of Ray Lawson. He listens to what I want (and don?t want) and provides a portfolio of options that meets my needs.
Good car.
Bought 2012 in 2021. I have put 18,000 miles on it. Had to do brakes, CV joint, and the thermostat. Otherwise, it runs very good.

2024 GMC 3500HD AT4
This review is for a two week old truck. I have been trying to get a 3500HD AT4, gas engine, 8 foot bed, 5th wheel prep, in blue for over a year (almost 2). My dealer finally received an allocation and I was off for the build!! However, when my build order was sent to me the color had defaulted to black (blue was discontinued for 2024) and the only way to change it was to cancel and start over.....so black it is!! The truck is gorgeous and much larger than I thought! I am pleased with both exterior styling and the 2024 interior refesh. My only complaint is the seats, they are a bit firm.....still comfy....but firm. The GM sunroof is small, so small I passed on the option. Mechanically this truck is a pretty sound design. Another 50hp for the 6.6L gas engine would be nice, but 401hp is pretty decent. A PTO offering in the up level trims would be nice, as would a larger/dual fuel tank option is needed (GM is the only one that doesn't offer one), and a factory level in the front, and while I am dreaming a front locking differential. GM could up thier paint game, when approaching 90k I expect better paint. Value wise it is as good if not better than the rest of the over priced trucks on the market. Rumor is 20K per unit on average goes to the UAW pension, that's why your 50k truck costs 70k. In closing I have zero regrets other than the color, but I needed it immediately so here I am.

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.

Overall I am very happy with my new Truck. GMC however needs to address their software glitch where the display screen intermittently stops working or the audio cuts in and out. I keep hearing a software update is being worked on but that was a while ago?

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!!
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

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.
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!

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.

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.

I saw this car driving by the dealership and automatically was drawn to it because of its color. GMC calls it brown but one print out called it crystal metallic purple. It changes colors depending on the weather. I love the handling, the dash and all the bells and whistles! My grandchildren love how much room that it has!
