Used GMC Sierra 1500 SLT for sale near Duluth, GA

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!

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.

Al and Brooks are excellent service advisors. You will be pleased with their professionalism. You will not be disappointed in this dealership or their service bay

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 !

Very helpful, eager to help me find a car for my needs . Prompt and knowledgeable

Let me start by saying I have the AT4 model with the Duramax 3.0L diesel. I had a 2024 Elevation with the 5.3L V-8 that I bought to pull my 22’ camper. While the Elevation pulled my camper fine it drank the gas like it was on a binge. And with a 26 gallon gas tank it seemed I was filling up every couple of hours. After one trip to Nova Scotia I knew something had to change. I pulled my camper out west to Yellowstone and back through Arizona. It pulled like a champ and fillups were a lot more manageable. Even driving the speed limit out west I still got four to five mpg better than with the gasser. I liked the Elevation but I love the AT4. Way nicer ride and great handling. I get 30 per gallon of diesel on the highway if I drive the speed limit but I got it to tow with. I added a Titian replacement fuel tank so I have 43 gallons instead of the 26 it came with.

Autonation made servicing my VW ID.4 a smooth, hassle-free experience. The staff were very accommodating, and my service representative was professional, friendly, and easy to work with throughout the visit. I?d definitely recommend Autonation to anyone looking for reliable service.

I own a 2023 Sierra 1500 Elevation equipped with the 2.7L TurboMax, and it’s been outstanding. It currently has 23,000 flawless miles. I’ll admit, I was skeptical of the 2.7 at first, but I jumped in feet-first and have never looked back. Living in Colorado, I regularly tow a 5,000-pound travel trailer through the Rockies with zero performance issues. The truck pulls confidently, handles grades with ease, and still delivers impressive fuel economy—23–24 mpg on the highway and about 18 mpg in town. I couldn’t be happier with this setup. If there is a negative to mention, that would be that after three years of ownership, the black wheels havent grown on me, and Im beginning to hate em. :) Lastly, the mpg while towing drops to 9mpg which is similar to that of a V8. All said, its been a great truck. :)

Capital Buick Service Department has truly outdone themselves with strong regards to a remarkable Customer Experience, superseding mediocre Customer Service - because, yes, there?s a distinct Difference!!! They?ve been servicing my vehicle for the past six and a half years and I?ve Never, nor Will Ever consider patronizing any other dealership or auto body shop. The dedicated assessment, consideration and astute attention Team Leader Doug Aldridge provided, gave me peace of mind in preparation for my extensive ?road-trippin? ? journey ahead. I highly recommend entrusting this establishment with all of your car maintenance, detailing and repair needs. Thank you Doug and Allen for being Professional, Accommodating and Reliable - you both are Greatly Appreciated!!

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!

Even the service was good. The technician left trash from his snack in my vehicle. An didn't put back my battery cover under my passenger seat

This truck is the base model and that is exactly what we were looking for. A good solid truck without all the fancy technology. It drives like a dream, handles just as well and the interior is sleek and well designed. Perfect black on black exterior.... a man's truck.

Good afternoon everyone, yes, I’m a lady and I’m an owner of a 2017 GMC Sierra 1500 Denali, it has a V8 motor fully loaded sunroof & also it has heated seats & steering wheel for the cold winter months & in those hot summer months you have A/C seats nothing better than that am I correct? It’s been times like that wouldnt trade for the world!! So for all you ladies who think BIG TRUCKS are just for men, go out there & buy one have them put on some electronic slide in/out rails & go out & show the shows the boss!! lol 😄 I’m out looking for a new one now either a 2500/3500 pearl white

Been buying from Hardy Chevrolet since 1982 and never had a bad experience

Smooth ride strong motor decent gas mileage inside cab is loaded and very tastefully done along w easy access to knobs. Plenty of room. In back seat ! Aclassy looking Truck with a tacky looking owner!!

Motorpoint Roswell is a unique used car dealer. A great number of their vehicles are one-owner, very unusual for a small dealer. Alyque and Rich were great to work with, and took time to answer any and all questions. Good, honest hard-working guys who are definitely turning the perception of a used car dealer to a positive. If you are looking for a CLEAN used vehicle, people who will shoot straight with you, then you MUST contact them!

Am in disbelief every week at the Gas Pumps. Thou a big truck, mileage per gallons are 18 +. Last week it was 22.8. This week 19.78.

Everything has been good so far.. I love my new ride. Im Just waiting on tag, title, plate etc.. I'll give a full review after that..

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.

Overall I am very happy with my new Truck. GMC however needs to address their software glitch where the display screen intermittently stops working or the audio cuts in and out. I keep hearing a software update is being worked on but that was a while ago?

Call to about a concern with my check engine light. Was done fast an efficiently was a power train issue and was fixed correctly. Truck is running fine.

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.

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!

handles and drives great, the electronics don't always work, mirrors don't always work, spray with wd 40, check engine light, EVAP culprit, auto nation has no luck with this, will drive it till the warrenty expires and its back to ford for me

Michael Rogers did a great job helping me acquire a 2026 Corvette. He went out the way to make the purchase work. He is a very good communicator and very knowledgeable about the Corvette. I would recommend Michael to your next car purchase!

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

Very very satisfying. One can truly feel confident with a Service Director as Mr. Quinton steadily proves; your Vehicle - Truck or Car - is in the best of hands at Capital GMC / Buick.

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.

Had a great and outstanding experience with Troncalli CDJR!!! Was looking for a used, safe, and reliable used vehicle for my daughter. Went to a lot of vehicle dealerships to look for her used vehicle, however Troncalli CDJR, was the dealership that really stood out. From the super nice and helpful receptionist to their nice, understanding, and accommodating manager (Brett), to an amazing salesperson and Veteran (C.J. Seaberry), to finance officer (Anthony). They did not do any high pressure sales, they address our concerns and request, and we feel really comfortable with our purchase and price, condition, and quality of my daughter’s used vehicle with this dealership. Thank you Troncalli CDJR for giving my family a very pleasant experience with buying our daughter her 1st vehicle. Definitely, hoping to buy all our kids their 1st vehicles from this dealership.

My GMC Sierra is the best ride I have had in all the years that I have been driving. I started driving in 1977. I love my new Sierra.

About two weeks ago, I found a Lexus RC 350 at CarGurus and I stopped by for some window shopping and ran into Lou, who was helping another customer at the time. Even though the showroom was busy, He took the time to greet me and reassured me that someone would be with me shortly. That simple gesture really stood out and made me feel valued, even before I made a decision. After doing my research, I decided to return to ALM Marietta, and I'm so glad I did! I had the pleasure of working with Lou again, and I also had the chance to meet some fantastic folks in both the management and finance team.

Alan was great to work with and made it very easy to buy my car. His follow through was exceptional. The car took almost a week to arrive at dealer, but Alan stayed in contact with me. I would recommend buying a car from Gravity. The prices are lower then a lot of other dealers. Overall good experience. Would buy from them again. Thank you!

Worked with Jessica- she was great and knew her stuff! Buying a car is a stressful experience, Jessica put me at ease and answered all my questions. Highly recommend

The truck has more features than I need. It is quiet and comfortable. it has plenty of power to pull a work trailer. Overall a nice truck
