Used GMC Sierra 2500 AT4 for sale near Chamblee, GA

Good job thank you!! He was very great. Got me the truxk I wanted verry happy.

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.

Great service Great response time Loaner car provided I would recommend this location Hours are good and convenient And their service consultants are very knowledgeable

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!

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.

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.

Vladimir was excellent, he was very professional and kept me informed of the progress. The mechanic did a great job and even provided a video. They fixed the issue very quickly and it was one of the best dealership experiences I've ever had! Five stars to Vladimir and crew!

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.

Only dealt with them via text. Very responsive to our needs. Decided not to buy anything at this time.

Cars and prices appear ok. I was looking may purchase later this spring or summer

Awesome experience! Jody and team were highly professional, honest and great to work with. My wife and I were extremely satisfied with our purchase and the overall customer experience. Thank you Team Palmer!

The people were a pleasure to work with. They Had the truck ready when I arrived. I showed up finished the paperwork and drove out

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 vehicle was taken in for service and the service advisor told me of a possible future failure of the serpentine belt. The service was done in a timely manner.

Josie fue un amor trabajar con ella. Ella fue muy atenta y servicial. Recomendación a todos que pregunten por ella. 100 de 10.

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.

Nolan Knox from Carl Black, Roswell, was so easy to work with in purchasing our new Sierra 1500 denali ultimate. Nolan was so professional and knowledgeable as he answered all our questions. I highly recommend Nolan Knox. Thank you for making this whole purchasing event less stressful. Charles & Deb

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

Good service, customer service and good folks to deal with. I appreciate their business very much. Benjamin, and Gabriel were much help!

This was an online purchase with salesman Roq Micheal’s. He was very helpful and made this online deal flawless. Reached a purchase price with Jonathan and felt confident to put down a $1000 over the phone. We had already did test drives in Chattanooga TN. ALM couldn’t even be beat even by Marshall Mize Ford. Great job ROQ.

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!

Melvin helped my younger brother with service on his first car . He was super friendly and had a great attitude.

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 was looking to upgrade my truck and met Nolan Knox who helped me look for the right truck. He was patient as I tried to make the best decision for me. He responded to all my questions even when he was off. I would recommend Nolan to help anyone with car or truck buying from Carl Black GMC of Roswell.

I recently purchased a truck with Ben, and the experience was excellent. He was highly professional, knowledgeable, and genuinely great to work with. I would absolutely recommend asking for Ben—he’s a fantastic salesman. Nathaniel Faulkner

What a gorgeous truck, runs good, sounds good and has all of the amenities I need although I am looking forward to their next interior upgrade.

We purchased a 2025 GMC Yukon from Nolan Knox with Carl Black. Nolan was great, kept us well informed. The purchase was simple and painless. We will purchase our next vehicle from Nolan and Carl Black.
