Used GMC Sierra 2500 trucks for sale near Milton, GA

I had a very positive car buying experience working with CJ. From start to finish, he was attentive, objective, communicative, and transparent. He took the time to answer all my questions, kept me informed throughout the process, and made sure everything went smoothly. I really appreciated his professionalism—no pressure, just helpful guidance. Highly recommend working with CJ if you're in the market for a new vehicle!

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.

Excellent personnel with professional and personable approach who want to work with you for your business. We visited twice and decided to go with Mazda Mall of Georgia after seeing the less than authentic and straightforward approach of other dealerships. Chris Myrick was patient and understanding as our circumstances changed and we needed to go with a used Mazda instead of a new one. Excited to make this our dealership of the future when I’m ready to trade for the upgrade. Excellent experience!

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.

This was the best experience I have ever had buying an automobile. My salesman was very honest with me and very knowledgeable.

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.

Damien Brown was super helpful on the phone and even more so in person. This dealership has a huge inventory and he was very knowledgeable about all of the different cars available. There were no pushy sales tactics, and I never felt pressured. I would absolutely seek him out again if I were in the market to buy another vehicle.

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 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!

Dwayne was our service rep today. He was beyond expectations. He was very responsive and professional, making sure we were kept informed and that we understood the repairs. Great service!

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.

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.

Very helpful throughout the process. Definitely recommend Ben if you are looking to purchase vehicle.

Very tentative staff and great pricing. I dealt with Zack Pirkle for the second time now and process was smooth and quick just as it was before. My go to dealership from here on out.

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!

Nader was very easy to work with. He listened and answered all my questions. Only snag I ran into was a fee that was tagged on was not mentioned until time to sign paperwork. When questioned rate was reduced. I love my odyssey

I visited this dealership and had the best customer service experience from a chick named Bri. We love the new car and will definitely be spreading your name and the dealership name as well throughout the ATL. area!! Thanks again Bri you definitely did your job!! Sincerely, JB&Family!!

Kentazne and Jim was great they helped me get my dream car and I appreciate them for going above and beyond the whole team was helpful

Aaron, and his team, Josh are amazing service team and excellent customer service. They will go over and beyond the call for giving excellent service. John W

I love how the truck pulls and rides when towing. It will give any driver the confidence to tow anywhere. I haven't had a single issue with it. I love the way it looks and couldn't be happier.

Great service. Prompt service and did an excellent job. Job completed as promised. Service advisor Casey kept me advised of service that was needed and let me know when the vehicle was ready.

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.

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!

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!
