Used GMC cars for sale near Mableton, GA under $899,990

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 bought this 2017 Tahoe w LT trim new. Have 60K on it now and have had no issues with it. We are not towing with it or doing high speed racing so we find the 5.3L Motor is smooth and quiet (and have not had any lifter issues which others have reported). Transmission and suspension also smooth. We keep Michelins on all our vehicles and have found this Tahoe very quiet and comfortable for road trips with 4-6 people and luggage. The LT trim pkg deleted some comfort items I wish I had (like heated steering wheel) but it still is pretty much leather-and-loaded so it was a good value at the time. I have had Suburbans for 35yrs before purchasing this Tahoe and I will probably go back to a Suburban for the extra cargo space when I trade this Tahoe in. But this has been a nice and reliable vehicle for us. No complaints.

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!

Stong engine and smooth! Highly recommend for familys or someone who likes a smooth truck. Purchased new and have had zero issues since then. Love it!

Outstanding professional. Patient and accommodating. Excellent customer service. A pleasure to do business with. Great attitude.

check the oil every tank fill, dealer advised if it dropped too far it would scrap the timing chain, interference engine lock up. a 6 inch strip of paint blistered off the roof, the rear deck won't set down horizontal (everything slides to the rear. rides like a limo, handles like a dream, no real probs. 168k on the odo.

Peter was the first person who helped me and was very helpful, when I had a family emergency he held my Mustang till I could get in to see it. Kern was the individual who I saw when I was able to see the car. He was very helpful and got me quickly through the process. The only problem I had was the rocker stripe was missing on the passenger side is missing and they have not been able to get it replaced. Hopefully it will be resolved soon.

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.

The salesman I interacted with throughout the process, Stan, was awesome and worked hard to find the vehicle I wanted. I had a jeep wrangler 4door and wanted a 2 door. We got the deal done and while driving home I had some buyers remorse not because the car wasn’t what they said it was but because I was just a bit attached to the 4 door and didn’t know it. After being approved for financing, signing the papers and nearly getting home with the jeep, I turned around and went back telling them that I wanted my jeep back. The management there was super understanding and quickly accommodated me when they didn’t have to. I was very grateful for that. One negative thing I would say is that my trade in was worth more than the vehicle I was getting from them. When I arrived I was wanting some money to boot from them or at the very least trade them straight up but instead they came to me with a 6k balance that they eventually worked down to just below 3k. They talked me into financing 3k. I told Mike (the finance guy) I would likely be turned down because I pay cash for everything and he said my approval was guaranteed because “I had equity” which is directly telling me that my car was worth more than the one I was getting and yet there I was being talked into financing a balance. They coulda traded me straight up and still made money. I likely wouldn’t have brought their jeep back if they woulda done that. I don’t understand why they would force me to finance to get the car that’s worth less than mine. There was plenty of meat on the bone.

Beautiful facility. Employees very courteous and professional.

This was the easiest car buying experience I have had. They took me to the car I was interested in. Keys were there, we drove it right away. The price was competitive, the financing was lightning quick. They washed it while I was signing and I was out of there in under an hour. They even drove me to turn in my rental car so I could just drive my new car home and surprise the family. First class business.

As we age, our reaction time may become slower. This vehicle is loaded with features that make me a safer driver. It connects wirelessly with my iPhone for hands-free Apple CarPlay. Love that! And the Acadia is a dream to drive. It’s the perfect size for me and my family

We had a great experience with Grand Motorcars. All the sales staff were friendly and made us feel welcome. Jhordan and Erika helped make us a great deal. We would buy from again!

I had amazing Fast Pace experience even though it took me 3 days to get my car due to My inability to provide the documents they needed.however going on the lot getting pre-approved over the phone walking in and walking out with my vehicle was the easiest process I've ever faced. John was very helpful and Adrian was the greatest he worked with me every step of the way and he made sure I drove off the lot with the car i wanted. Even more so when I didn't even think or believe they can get me financed and not to mention they put a bow on the car I felt very special and the customer service made me feel very confident I am so grateful for you guys thank you so much CarMax!!!!!!!!!

I've owned this GMC Sierra 1500 All Terrain since it was 8 months old. With the exception of two warranty issues (failing power brake vacuum pump and transmission electrical harness), I have been totally happy with this truck. Up until now, my 1996 Chevrolet K1500 Silverado with it's 5.7L Vortec engine was my favorite truck of all time, this GMC (5.3L LS engine, 8 speed automatice) has earned the top spot now of my all time favorite truck. It is comfortable to drive, and runs as good as the day I bought it over 5+ years ago. I've got 71.5K miles on it. My biggest issue is I wished it had the 6.2L engine for better towing capabilities. Other than that ... love this truck.

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

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.

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.

GMC Canyon Denali with the 2.7 Duramax diesel is a loaded power house with great fuel economy. 4x4 has a towing capacity of 7000 pounds, the best in class. 31 MPG on the highway! Previously owned a Tacoma but it would not pull our travel trailer with the V-6. Highly recommend the Canyon diesel, if you can find one!

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.

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.

Alonzo Gamble, and Nadeem Khan such a good dealer , am happy with their services . Thank you AX Auto.

This truck has a jerk when changing gears sometimes. I enjoy the truck overall easy to handle and comfortable. Drive with ease sight is good when driving.

Excellent choices to choose from and very easy to buy and sell your next car … and and the site has great options at the tip of your fingers thank you cars.com for a great experience…

Everything I want in a vehicle. I love the interior and the slick look of the overall vehicle itself. Oh can’t forget about all the different options Available on this truck. It has so much to offer!

America’s Xtreme Autos provided exceptional service from start to finish. The staff was friendly, knowledgeable, and attentive to my needs. I found the perfect car at a great price. Highly recommend!

We drove two states over to McKenzie Buick GMC in Milton, FL to meet with Nick and make a purchase on our new Yukon Denali. Customer service was top notch. We were going for their 2019 Yukon Denali to replace a 2008 Tahoe LTZ. We are very pleased with the vehicle. The upgrades are wonderful. Love the cooling seats, the wifi, the HUD and even days after our purchase they have reached out to check on how we were and mailed us a small gift that meant so much. We will definitely use them again if they ever have what we’re looking for on a future purchase. - Brandon Howell 2019 Yukon Denali

This was an excellent choice. I really appreciate the patience of the dealership working with me. I think, thought, and over thought this purchase trying to look at every possible angle of why get this vehicle. They had no pressure to buy. They answered any and all questions. They kept offering water/snacks and other amenities for comfort. But no pushy pressure. Patience should be in their title. It was a better experience than I’ve had at other dealerships. Final choice was the iD.4 which they explained everything up front and worked with me to iron out a deal. I tried to look for clues to them being shady or sneaky but it wasn’t there. I feel good about my purchase and would highly recommend them to others. Well done.

Just trade in my 2015 GMC Denali with 140000 miles on it and still holding strong at trade in best SUV I ever had upgraded to the new 2021 Denali and boy do I love this SUV from comfort to outside design just an amazing new well designed SUV.

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.

I didn't buy anything from them but they seem to be and excellent dealership.

What a spectacular experience. I usually buy used cars, but went ahead and purchased a new 2023 Q8 Prestige. The ONLY person to work with here is Ahamed Eboo. He is wise, professional, transparent, and listens to each and every one of your wants and needs. This level of professionalism has, for the most part, dried up in the car business, not with him and not with Audi of Marietta. This place is very modern and amazing. Before the purchase he guided us every step of the way. Then upon arrival of our 2023 Q8, we went to the dealership and he made the purchase 1000% pain free. I would buy again when I am ready. He sits in the car with you for 45+ min and shows you each feature. Which you usually take 6-12 months to discover by yourself. Not with him, it was important to him to make sure we saw all that this amazing beast of a vehicle has to offer. Come here, ask for AHAMED EBOO, he is the only person with a desk inside the show room, goes to show you how long he has been great here.

Just purchased this vehicle a little over a month ago. Love the ride, the comfort of the seats, and, the body style. My only complaint is that it drifts to the right and the steering wheel is several degrees to the left after two trips to the dealer where we purchased it. I will probably have to pay to take it to a known, excellent alignment shop.

About two weeks ago, I found a Lexus RC 350 at CarGurus and I stopped by for some window shopping and ran into Lou, who was helping another customer at the time. Even though the showroom was busy, He took the time to greet me and reassured me that someone would be with me shortly. That simple gesture really stood out and made me feel valued, even before I made a decision. After doing my research, I decided to return to ALM Marietta, and I'm so glad I did! I had the pleasure of working with Lou again, and I also had the chance to meet some fantastic folks in both the management and finance team.

I love it the look the interior mine is a red one and it looks so good and it’s my baby and it runs so good and the technology is off the chain
