Used GMC Sierra 2500 AT4 for sale near Suwanee, GA

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!

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.

I recently purchased the 2023 Mercedes-Benz GLE 53 AMG, and the entire experience has been nothing short of amazing. Not only is the vehicle a true standout in performance and luxury, but the team at ALM Roswell made the process seamless and enjoyable. The combination of the 2023 GLE 53 AMG's performance and luxury, paired with the outstanding service at ALM Roswell, made this an unforgettable experience. A heartfelt thank you to ALM Roswell for making it so easy to get behind the wheel of this incredible SUV. Highly recommended! Big thank you to Bri and Marquese Norman

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.

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.

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.

here at Gravity you are in good hands. rest assured you will drive home with your new vehicle . adam in sales is who you should look for indeed

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 experience 5 stars all around they have some of the best prices in the market.

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!

The staff at Dena Motors is exceptional! They were prompt, courteous, and attentive from our first encounter. The employees sincerely care about giving guests a positive experience and communicate effectively. Everything appeared well-planned and professionally done. A dealership that is this responsive and easy to work with is uncommon; they are undoubtedly a team you can rely on!

Ben was amazing. There was some hiccups, but he treated us with respect and honesty. It was a great experience overall.

Benjamin Clark was an excellent young salesman. My wife and I were very impressed with his professionalism and courtesy. I’m satisfied with my purchase and have peace of mind from my shopping experience.

Service reps are always cordial and friendly! They go out their way to make sure customers are pleased and comfortable. The manager, Aaron, along with Josh and others are always pleasant and caring. Mr. Niko, the driver who takes customers to various destinations, is always smiling and making sure you are satisfied with service, etc. Always excellent service in any category!

My rear tail light was out so I scheduled my appointment with my advisor Melvin.

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.

Pay attention what get in your hands paperwork throughly read it carefully and see everything they put in it such extra extra cash that you didn’t say and extra money makes it go up higher that you can’t afford the extra payment.Now you see how much gap insurance $$$ added in the paperwork and makes sure you get a lawyer go with you when getting used filthy car full of dog hairs.Makes sure you have mechanic on hand too.They will sell you a car without license which is illegal.Don’t use no co-signer.Don’t use Ally financing on new or used vehicles.Even if you pay it off tell you getting gap refunds on mailing letter.they will keep it cause you don’t qualify for it.Keep up with all your paperwork in a file and payment history on papers like print out.Get your payment down as low as you can and 84 months is long ways to go.Do research how to save money on used or newer car without all that crazy extra add on.They’re trying make money of of you even on the elderly people.Have a great day everyone

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.

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

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 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!

Kenmanuel did a great job working on getting me the truck. He explained everything to me and made sure I understood what was going on.

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!
