Used GMC Sierra 2500 trucks for sale near South Fulton, GA

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!!!

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.

Everyone was friendly and very helpful. My salesman Riley was especially helpful and patient with me making choices and costs. He also walked me through setting up phone ,etc.

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.

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.

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 love my 2021 GMC Denali 2500HD. I have gotten more complements on this truck than any other vehicle that I have owned. I get great highway fuel milage average 19-26mpg,which is great for a heavy duty truck!

The staff was super friendly and explained everything dealing with my vehicle also the process was completely hassle and stress free. I was also offered a shuttle within a 10 mile radius if I didn?t want to stay at the dealership.

I paid over $106,000 for this truck with warranty. Do not care much about miles per gal. at that that price range. Just too much truck for me at my age.

Everything was fine except, of course the long wait time. However, this time when I got my truck back it had an unpleasant odor in it. I drove home with the windows down and then washed the floor mat and it's much better.

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.

The service advisors are always pleasant and thorough but basic maintenance services take some time so exercise patience if you can. About 2.5 hours for an oil change and tires rotation. Should not take that long with an appointment in my humble opinion. I only visit occasionally for this reason and go elsewhere the majority of the time.

Love my GMC. Owned a Chevy and this absolutely beats it hands down. Never had any issues. Inside is very comfortable and can't imagine driving anything else

Had Marcus as my salesman. Very awesome experience. Help me get the truck I wanted worked with me and got the deal I wanted. Never pressed or made me feel like I had to take the deal.

Love everything about this Duramax Denali except the fuel mileage. 13-14 Mpg tops when not towing. Bought truck cause previous was stolen. Wish I still had my 6.2 High Country!

Thank you Radi for your help! Radi is always professional and friendly. Whenever I come here and makes sure that everything is done with quality and efficiency. This is greatly appreciated!

Bought 2025 Camry, we found it online and verified all the information over the phone. We set up an appointment for later in the day to complete the transaction. Our salesperson Inero was friendly and helpful and the final numbers were just as the manager, Thomas, had presented over the phone. At the end the financing manager did do his little sales pitch for all the extras (gap, extended, etc) which we all turned down, but he was friendly and understanding with our 3 little ones running around. Time we arrived til time we left was a little under 2 hours.

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 am really impressed with all the help from Mr Rocky Smith. Awesome person. I brought my vehicle at the end of Aug. I was having a problem with getting information about my tags and title. Mr Smith not only helped me with great information 👍. He makes sure to call me and text me with updates on my situation 🙂. He is a great asset to this company. Keep up the great work👍

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!

This truck is the truck that all others should look up to. It rides great, will tow a house, runs smooth, and gets great fuel economy. The Allison transmission is so smooth. The AT4 looks great too.

My car came in with the engine light. The service department found the issue, unfortunately was not able to fix it due to my warranty. Great customer service and assist me every step of the way

On 8/23/25 After an exhausting search, we were blessed to be connected with Lloyd (Lincoln side) of Hennessy Ford Atlanta. We were looking for a specific used car I saw online (that we learned was located on the Ford side) but our GPS took us to the Lincoln side. The entire process from start to finish went smoothly and Lloyd made sure we felt valued every step of the way. I experienced a level of customer service with Hennessy Ford that is definitely lacking at other dealerships.(If you've ever been to Gwinnett Place Nissan you understand). Even though it was a used car and not their brand, Lloyd still thought it not robbery to call us to see how things were going with the vehicle. Now, that's service! I highly recommend Hennessy Ford and Lloyd to anyone needing a new or used vehicle.They really do care about their reputation!

Gustavo is awesome! Very helpful and was able to fit me in to get the rod to my alternator rethreaded and secured. Im very pleased with my experience and will be coming back.

We did almost everything over the phone and it was so easy. Bennie was an awesome salesman He listened to what we wanted and made the experience very enjoyable.

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.

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!!!!
