Used GMC cars for sale near Union City, GA

Awesome. Simplicity. Elegance. Lloyd and Andrew solved all our problems with a wonderful solution. All of which made my wife happy. I looked like a hero.

I recommend going to Jim Ellis in McDonough. Shanya is the rep that helped me and I have nothing bad to say at all she was exceptionally helpful with the process of getting me a car.

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.

Great service , definitely recommended to my family and friends. Will go back if I need anything else. Thank you cars.com for the best experience

Great truck to own. The 2023 GMC Sierra Denali with the 6.2L engine delivers excellent power, smooth performance, and a refined driving experience. The ride quality, interior comfort, and overall build quality are outstanding. I have had no issues whatsoever, and it has been a reliable, enjoyable vehicle from day one. I would highly recommend it to anyone looking for a premium full-size truck.

Tim H. continues to provide honest and excellent customer service. He is very knowledgeable and strives to make customers safe and happy. I appreciate all the help!

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!

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!

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.

Purchased new in October 2024. Total miles driven 9,276. Just completed a 4,734.2 mile trip through 9 states. Just a pleasure to drive. My wife and I were on the road 16 days, with only 8 driving days, longest day was 674 miles. Average driving speed was about 72+ miles per hour. Seat comfort was amazing, no discomfort, great considering having 4 back surgeries. Very solid on the road with little or no driving fatigue. Performance was great. Of the total miles, about 500 were in town driving and 300 miles was in 4x4 in a snow storm coming across Northern Texas in April. Average MPG was 26.4 with my best 500mile drive at 33mpg. The diesel engine is very quiet requiring me to check the tach sometimes to be sure I had pressed the off button. Very quiet on the road as well. This is my first diesel and I would highly recommend it. Plenty of power, great fuel economy, quiet and very responsive when you need that quick acceleration. amazingly nimble for a big SUV. The adaptive cruise works great. My previous GMC was a 2009, 6.2L V8 Yukon XL. I drove that one 140K miles over 14 years with nothing but routine maintenance, a great vehicle as well. Very happy with this 2024

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!

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

Any reviews on this vehicle is not correct. We are first owners and it’s been an excellent truck. We hate to see it go !

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.

I bought my 2020 with 36k miles a couple of years ago and I now have 60k miles of trouble free very enjoyable driving. It was expensive, but worth every penny. The ride is so quiet and comfortable my wife and I prefer traveling in it instead of our 2018 Acura MDX which we also love. The 5.3 V8 has plenty of power and towing ability. The multi-function tail gate is genius, I hope to never be without one again. We so enjoy all the bells and whistles, especially the wireless phone charger. So glad I bought this truck!

The customer service was great. I have tow complaints: 1. A 3% surcharge when using a credit card which everyone pays with. 2. The waiting room was freezing. I know it?s extremely hot outside but it was very uncomfortable in the waiting area.

2021 GMC sierra 1500, 5.3, crew cab 4x4, 21000 miles. brakepad monitor lites up. dealership says needs brakes and rotors in back. one mo. on warranty. our rural roads dirty up the monitor. Needs new monitor. brakes look great to me. No noises. dealer says parts on order GM strike. Can't replace myself cause of computer...

I came from Columbia SC to look at a Jeep Sahara I saw online. Greg greeted us at the door and got us into a test drive and then purchasing the vehicle without any issues. He was friendly, efficient, and made my car buying experience a breeze. I would recommend ALM Marietta to friends and family, and ask for Greg!!!

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

Awesome experience with Greco. He explained everything and was very cleared and transparent. I would recommend him to whoever wants to buy a car. Greco was very professional and kind

My truck has a great appearance, inside and out. It is a pleasure to drive; and rides and performs great. It is the best truck I've ever owned.

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.

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.

It was a wonderful experience. Jon was very informative and helped us find exactly what we wanted!

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.

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!

The salesman was wonderful, fast, smooth process great experience. Finance processes quick and easy can?t say enough about them. I would definitely purchase from this dealership again.

Nice styling,interior has a new design dash which is beautiful and convenient,safety features and cameras are great and easy to used and the active cruise is awesome.

Cory and the whole staff were very kind, welcoming, and very informative. I had a wonderful experience. The facility was clean and the snacks were tasty!

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.

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.

2024 GMC sierra 1500 duramax 3.0 is great truck. Great ride and great MPG. 100% recommend to any prospective buyer. Love the truck and how it perform.

The service department was awesome. Lamarcus Tenny checked to make the service visit was top notch. I plan on bringing my car back in the future!

As always quality service. Knowledgeable people handling vehicle. Great waiting area and the offer of water. Sales floor could be a little more accommodating to the customers needs.
