Used GMC cars for sale near Powder Springs, GA under $1,000,000

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.

I ordered a 2022 3500 SRW Pro LB Double cab 4x4 in silver metallic / blk cloth. Added preferred package; gooseneck pkg; X31; upgraded wheels; camper/Snowplow prep; black steps. Got the 6.6 gas L8T. No start/stop and runs on all 8 cylinders all the time. I Love this truck. Had Rams and Fords in past. This is my first GM truck. I am in my 50s so not a brand thing... just a great truck. It was delivered in June. Truck rides great, tows very well, reciever or gooseneck. Fuel mileage is outstanding! Especially for a 4x4 one ton. I get 16 to 18 highway when not towing. I was shocked by how well it did and impressed with towing mpg as well. I generally tow between 6 and 14,000 lbs. Loads include a Glacier bay catmaran boat, 30' camper, and 3 axle 25' gooseneck. Truck easily handles those loads. The L8T engine is smooth and powerful. The 6L90 Transmission functions perfectly. If something were to happen to this truck I would not hesitate to order an exact replacement. So far very satisfied. MSRP as ordered was $53,945.

Cole was professional and answered questions carefully. I appreciate the fact that I can rely on trained professional people monitoring the condition of my car

We purchased the Denali Terrain 2023. The car is great. I have had four knee surgeries and needed a car to get in and out easily and comfort seating. The controls for adjusting the seat just the way you like are great. I am troubled also by back problems and totally love the heated seat when needed. Sometimes I just want to ride around and turn the heat on and adjust seat so my back feels better. The different controls and are numerous. I love the safety control warnings and info with traffic. The screen is fabulous and helps so much. When ever I park I like to drive in and park and then hold on brake put it in reverse so the screen then comes on and shows how I parked. I like the levers in cargo area for putting seats down and also like how flat they sit. Plenty of room. The back seat is roomy even when person in front is back. Enjoy being up higher than a vehicle. I feel I can see more and it also makes me feel safer. The Terrain looks beautiful and love all the chrome in front. The car seems bumpy but not as bad as our last. The roads are in rough shape here. It has a lot of pick-up my husband demonstrated that to me and he wont be doing that again unless it is necessary. It is a turbo 4 cylinder and can not believe the power you feel. All in all Iove the car and getting good mileage. Purchased car from Boucher in Waukesha. They were not pushy. Explained everything in detail and were very fair. Great place to purchase!

Easy and fast tire install, will be back for future service needs.. Quick, Affordable, Balanced, Tires, Workmanship, Quality.. Aquaman was great to work with, Thanks again!

I always bought the GMC Acadia (4 times) but decided to try the terrain. I absolutely love it and it's a great car for zipping around in town. I would take it for a weekend trip but not on a long trip as it doesn't have a lot of cab room, but for two people it is fine

Every one was pleasant but the truck I was interested in was sold. I looked around at some cars and trucks and left

I brought this truck in 2019. I kept taking it back to the dealership to get tweaked several times. Once it was figured out, never got any problems ever again. A little weak on the power side, but, other than that, its a magnificent vehicle. A total work horse. Great on gas. It is totally worth it.

Very helpful, eager to help me find a car for my needs . Prompt and knowledgeable

GMC Diesel Canyon AT4. I've had this truck for a year-11,000 miles. I love it. The Denali and Elevation trim looked like junk. The AT4 can't compete with the Tacoma off road but, It holds it's own off road. The Diesel pulls like a beast and the exhuast brake, on all the moutain passes I drive, is worth it's wieght in Gold. I trailer the max. capacity regularly and it's smooth sailing. I traded in my 2500HD Silverado with the vortec 6.0 for this big, little truck. Best decision I've made in a while. I had this truck on order for 8 months and Gm never accepted the order. I finally found exactly what I ordered, just off the truck that morning that I called. 1300 miles away, I jumped on a plane to go get it. Crying shame GMC discontinued the diesel. The extra $ per gallon right now is easily washed by the increase in mileage, 32+ higway, 19 trallering almost 8000 #'s. I wouldn't want the truck without it. Wouldn't want the Elevation or Denali. Diesel AT4 is the truck. I'll keep it the rest of my life barring accident. I'm sure I can get 40 years out of this truck doing 10-12k a year. The regeneration of the exhaust has never come up but, I only do a little round town driving. Most of my miles are highway and hauling a load. I've heard horror stories about regen. from city folk, commuters... You get what you aim for. If you've given it a lot of thought and the diesel AT4 seems right for you, you won't be disappointed. Good luck finding one. GM - You've a winner here. don't let it get away. Ps. Cars.com doesn't have a choice of how I use this truck for WORK. And wouldn't let me submit this review without selecting one of thier 3 inadequate choices. So, I selected having fun cause I believe everything should be but, this is my WORK TRUCK!

A smiling face met us at the front door and that set the tone for the rest of our visit. Everyone we encountered was patient, helpful, and genuinely nice. Great experience.

2019 Canyon Denali. All sorts of bells and whistles, several that I don't really need. Biggest complaint: no memory seats and no Homelink garage opener. Ridiculous. What accountant made that decision?

Kim Nichols rocks, and Sean is also excellent. I ternrt ad, we have emailed and spoken, but not too much!!! Waiting to hear if I'll be able to upgrade. They str excellent sp far!

Our AT4X has been an excellent mid-size truck. The ride is shockingly smooth and the engine has a lot of torque. Wish the interior had less plastic and GM's failure to have a rear view camera mirror or controls for garage/gate contols is inexcusible. Overall, could not be more pleased with this truck.

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.

It was a great experience working with Allen. He made sure that the process went smoothly and quickly. I'd go back for another car. Everyone was great!

One very awesome vehicle. Checks all the boxes you need in a truck and exceeds expectations on quality, performance, and looks great ,too. Love my nre truck.

Great place. Great people. great car. Allen and vic did everything amazingly. Worked hard to get me a good deal. Ri go was exceptionally enjoyable,friendly, and accomidaring.

I love my car. I love the way it handles, and the confidence I have in it when I’m on the road. The room in it is fantastic. All the room I need for when we travel.

Worked with Tammy in the Service department. everything went well. service was great. received oil change and diagnostic.

This is a luxury suv with plenty of room. I'm still learning the features. It is a smooth ride with a great interior. Great for towing a popup camper.

Grant, Cody and Jeremiah were great. Years ago I had a horrible experience at this dealership but todays experience was awesome. They each took very good care of me and made my buying experience memorable. With this team I would purchase from them again.

This truck is everything I wanted! GMC, 4x4, Lifted, Low milage. It's going to be great for my hunting and 4 wheeling! I love it!

Very pleased with service I received. It honest, helpful and answered my question and concerns. Greg was able to satisfy what I needed and I would recommend purchasing a car from this dealership.

I love my Acadia Denali. It is fully loaded with anything you can think of.I love the V6 engine and how smooth it drives and rides

Notes on the multi point stated my vehicle needed a lot of service, but none were explained. The receipt mentioned the rear differential but also not explained.

I've owned every other American truck and this is my first GMC. I bought the 2500 HD Texas Edition. I absolutely love this truck. It's everything I could have hoped for and more. It is able to pull my 30' travel trailer with no problems. So now when we go out with our trailer I'll have no worries. The look and feel of the truck is outstanding. The 6.6L gas engine actually gets great gas mileage. It gets about the same as my Ford f150 ecoboost. Probably better on the highway. Looking at about 13 miles in the city and 15 plus on the highway. Definitely got a better truck for the price compared to any other american models with the same characteristic and options.

I have now worked with Bryan, Tim Burton, and Drew and they have all been amazing!!!! They were very knowledgeable and helped my find the vehicles that i wanted and made the buying process an easy and smooth process. If you need a "new to you" car go see any of the three of them and they will help you out!!!!

great styling and interior. nice features and acceptable performance. overall my Denali is a superior product to similar vehicles. I would recommend this GMC Acadia.

I would purchase from them again in a minute. Very good vibe. They all obviously have a great culture there. It rubs off on the customers. Good value for the money.

I have loved and owned Chevy and GMC midsized trucks since 98 when I purchased a used S-10. My latest purchase is a 2021 GMC Canyon Denali bought brand new. It's been a great truck until my power steering unit went out due to corrosion. It only has 32,200 miles on it and I have never gotten it wet other than car washes and driving in the rain which is normal conditions. I had purchased a mid grade extended warranty through GMC after my lease was up and purchased the truck. I am being told this is NOT covered due to it being external wiring. So I feel this is a manufacturing malfunction and bad engineering for water to be able to get in to cause such corrosion so beware. This is an open case filed with GM currently to hopefully rectify the matter.

Avery was my service advisor he was great and very knowledgeable and a very nice person all around

Missing a few things that could really make it better. Homelink for garage door isn’t offered? Doesn’t come with a receiver type hitch however what does comes with it is almost the same amount of steel. The phone charger doesn’t work quite right and they know it.

Diana cares about her clients! Diana is customer centric. Transparent. Knowledgeable. Trusting. She makes my problems dissappear. Thank you. Thank you for who you are.

I fell in love with my GMC Terrain when I test drove it and have not lost that loving feeling! I have received tons of compliments on it.

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.

One of the most attractive looking t cars GMC has ever designed. Looks just like a Lexus. Extremely roomy. Love every aspect of my Terrain.

Donte, my service representative was great and he got everything taken care of that I needed. I was able to wait in the customer waiting area.
