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

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!

I Think Frederick Stewart is one of the best. He’s passionate and will do whatever he can to help you get approved for a vehicle. Thanks for all your help and hard work.

I love that Ford now offers mobile service, having a tech come to my home for oil changes is a game changer. Scheduling is simple, and the convenience is unbeatable. No more waiting around at the dealership.

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.

I have enjoyed my vehicle. It is comfortable and drives very well. I like the color also. It is very roomy, takes off fast and the safety features are very beneficial.

I had the GREATEST experience here. Quality customer service, very professional! My sales consultant Wallace is AWESOME!! He made the process very easy and I was driving off with my car in less than 2 hours from arriving there. I would definitely recommend this Carmax and Wallace to anyone searching for a car! Please make sure you ask for Wallace, you won't be dissapointed!

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.

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!!

The Yukon checked all of my needs, I have plenty of room for my children and my Great Danes. I enjoy driving the Yukon and how it handles, overall love this vehicle!

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 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

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.
