Used GMC Sierra 1500 trucks for sale near Morrow, GA

Had a great experience with this dealership. My sales consultant Dexter Meadows was very thorough and made the sale very streamlined. Thanks

Great truck, solid engine, comfortable, smooth, and it handles great for such a large vehicle. Get one and enjoy miles of roadtrips with all you can tow or haul.

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

I purchased a new 2019 SLT with the X1 package. It has the Red Quartz Tintcoat paint. I usually never leave reviews, but honestly this is the most comfortable, nicest loking truck I've owned , and I've ownwd alot of them. The only issues I've had was the brake software was flawed, took it to the dealer on recall and they installed a new software patch, Other then that I love the styling, performance and the interior is very nice. No regrets

Quite effective customer service, I was contacted very quickly, they responded instantly and are very friendly

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

Todo estuvo muy bien y muy f�cil la compra Geovanny realmente nos ayud� mucho

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.

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!

Looked at more expensive truck with less options, bought the GMC SIERRA AT4 Turbo Diesel 6. I now only put fuel im once a month. And long distance trips are easier due to better fuel economy. One of my best investments ever.

I had a great experience buying my car - our salesman, Derrick, made the process easy. He was very knowledgeable & answered all our questions. Highly recommend giving Derrick a call.

I bought a 2019 GMC Sierra Elevation. I traded in a FULLY loaded 2015 Sierra SLT, that I was really sad to see go, but the Elevation really sold me on styling and ride quality. I lost a couple high end bells and whistles, but the overall performance and look of the truck make up for it big time!

The services on my car were detailed and transparent. The speed of service was solid. The work was done professionally too. Service Department treats me very well too, very friendly group of folks!

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!

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.

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 !

I recently purchased a vehicle from this dealership, and my experience was mixed. Conner, the salesperson, was excellent. He was kind, patient, and very knowledgeable about the car. He took the time to thoroughly explain the vehicle and even went above and beyond by finding a charger adapter for me so I could charge the car. His customer service and professionalism were greatly appreciated and made the buying process on the sales side very smooth. Unfortunately, my experience in finance with Brian was extremely disappointing. When I declined add-ons such as GAP insurance and the extended warranty, his demeanor changed completely. He became belittling and spoke to me in a condescending manner. When I directly told him that his behavior was rude, he began slamming papers and a stapler, clearly trying to rush me out of the finance office. This was uncomfortable and unprofessional. In addition, the vehicle was not properly cleaned upon delivery. The interior seats and floor mats were visibly dirty, which was surprising for a newly purchased vehicle. I haven?t purchased a car in a while, and this experience showed me how much dealership culture has changed ? especially in finance. The overall purchase itself was relatively quick (about an hour, two hours max including a two-day process), but the behavior in finance and the condition of the car at delivery left a negative impression. Conner deserves recognition for his professionalism. However, the finance experience and vehicle cleanliness need serious improvement.

Got the duramax diesel and getting 24 city and 32 highway is very good. Truck drives nice and is very comfortable. My 2 issues with this truck is the backup camera at night is useless (very dark) and interior lighting is not very good. You would have thought a 78k truck would have footwell lights, but it doesn’t.

Esthephany was amazing to work with! Super friendly, answered all my questions, and made the whole process easy. Highly recommend asking for her!

When a company understands the consumer and can be honest about capabilities they can commit to, and perform for the coustomer. Why go anywhere else?

I bought this after going to the dealer just to look at colors. I had a 2016 Chevy 1500 LTZ that I loved. There was my down payment and took this Denali home. Only 2 options. Paint and moonroof. I thought my chevy with 3.42 gears was quick. This one goes with 3.23's. The ride is great. Fit and finish are perfect. My only complaint is this Bose/Apple play radio is not what the 2016 Bose was.

I had the GREATEST experience here. Quality customer service, very professional! My sales consultant Wallace is AWESOME!! He made the process very easy and I was driving off with my car in less than 2 hours from arriving there. I would definitely recommend this Carmax and Wallace to anyone searching for a car! Please make sure you ask for Wallace, you won't be dissapointed!

Its not easy buying a car these days…especially for a woman! Michael Tate sold me a car and really he did all the work!!! I signed a few papers and was driving away in my new ride. Professional and knowledgeable!! See Michael Tate for a great painless experience 😊

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.

Found the car I was looking for . Thank you so much. Great making business with y’all . The progress was fast and easy. Thanks

2021 GMC sierra 1500, 5.3, crew cab 4x4, 21000 miles. brakepad monitor lites up. dealership says needs brakes and rotors in back. one mo. on warranty. our rural roads dirty up the monitor. Needs new monitor. brakes look great to me. No noises. dealer says parts on order GM strike. Can't replace myself cause of computer...

I love my car, I love Mr. Dameon ! He’s such an amazing sales man !!! He did an excellent job. Go to ALM Newnan and see him!!!! K. McAlester

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?

Easy transaction, online paperwork. Great service and gave us an efficient buying experience. Would use them again

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.

Manasseh was healthful showed me how the vehicle worked and made the process seamless as possible

Hennessy Cadillac is by far the best experience I have had ever in buying a vehicle. This is actually my second Cadillac I have purchased from them and I have nothing but great things to say! From the sales department to service it has been nothing short of amazing. I am not easily impressed but everyone I ever encounter at this dealership handles me with care and respect. Entering a dealership as a single woman could be intimidating but not here! Terrance and management went above and beyond to make sure I leave happy every time. I pay attention to how others are treated and I will say I haven’t seen anyone actually upset even in the service department. The concierge level service of greeting me opening doors all things I expect from Cadillac are given every single time. It is always neat and clean on the premises. And most importantly my deals are fair and respectful. Desmond is usually my service guy and he is absolutely always honest and makes sure I am kept up to date with any thing my truck needs without feeling pressured to buy or upsale anything to me. Even once sending someone to pick up a key for my truck when the other one didn’t work. I went to another dealer recently and found a truck I really liked and test drove that I could have purchased but didn’t because honestly I didn’t get the same concierge service from that Lexus dealership. Hennessy and Terrance made sure all my experiences were top tier. I have owned a lot of cars in my life and have had good and bad experiences on every level but Hennessy has not disappointed me one time. Check them out ask for Terrance in sales and Desmond in service and I promise you won’t be disappointed.

I have a 2023 GMC Sierra 1500 Denali with the 3.0 Diesel engine. I have 20,000 miles on it at the time of writing this. Never owned a diesel before and now i don't think i will own another one without it. I LOVE the engine in this truck. Only complaint would be that it likes DEF fluid while towing so pick up some extra DEF before you head out to tow something. Put about 8K miles on it this summer without adding any DEF fluid. seems to use a little more in the winter or when towing. Very quiet for a deisel and the fuel economy is awesome. Driving 70 mph down the freeway this truck gets about 30mpg, Drive 55mph on regular highways and this truck gets almost 40mpg. All around driving for me is about 26mpg. I used to fill up twice a week with my gas motor and now only once a week. Wireless Apple Carplay works great and the voice texting and mapping is a big plus. I also have the new SuperCruise feature which is awesome. Get on the freeway and set the supercruise on and the truck drives itself until i get to my exit (about 28 miles from home to work). Bose stereo is out of this world and all the storage is great to. I have a swingout bed toolbox, aluminum roll up tonneau cover, Lighted black GMC front emblem, Gloss Black 22" wheels, All Black decals and my dual exhaust bezels are black as well. I rotate the tires and change the oil every 5,000 miles. Couldn't ask for a better truck. Might get the ultimate next time as that has the messaging seats which i kinda wish I had.

Dealing with the Dena Motors crew was fantastic! Everybody was really kind, approachable, and quick to answer any questions I had. It's clear that they genuinely care about their clients and want to ensure a positive experience. Highly recommended! They are a very professional and friendly group of people.

Great performance, hard to clean, everything, I expected. Getting lots of compliments and head turning. Stomping with thee BIG DAWGS!!!! Good gas mileage on highway.
