Used GMC Sierra 1500 SLT for sale near Forest Park, GA

Great experience with Hennessy of Southlake. Frank Parker was awesome and represented the dealership well. I flew in from Memphis, was picked up from the airport and everything about the car was as represented online.

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

Always very good service. Take very good care of my vehicle

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.

Customer Service was amazing and I will return. Very professional staff and kept you informed of the progress of your vehicle.

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 have the 1500 double cab with standard bed. The reason I have this vehicle is I really like the 6.5 foot bed. The crew cab with same bed is just too long. The things I dislike about this model is that it only comes in the SLE model. For the 2025 that means the external mirrors do NOT have a power fold in and it does not have a seat memory for more that one driver. The power fold in for the mirrors is extremely important to me.

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.

The Sales manager responded the next day to answer any questions and to invite me down to see the vehicle. Very professional and great customer service!

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!

All associates, especially the sales rep, were wonderful, professional, courteous, kind and easy to work with! All of my questions and concerns were answered and dealt with. The vehicle was ready for me to see and test drive. Everything went so well, I bought it!

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!

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

First class group there at Marietta Toyota. Brett, my sales consultant, was very knowledgeable about the car and was excellent to work with. Kudos as well to the management and finance teams for making the purchase process smooth and easy. I was very impressed with the used car sales team at Marietta Toyota and recommend them highly.

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.

I went to Carmax on 4th of July. The place was not super packed, so that was great. We had a little 9th month old on tow, and were nervous that it would take us all day to shop. The only thing that took a lot of time was waiting for a sales man. Apparently, the new young guys at the front were more interested in flirting (yes flirting) with each other and playing around than realizing that we needed help or just plainly asking us if we were being helped. That really bothered me, as we wasted 30 mins just sitting dumb. The front desk girl was no help.. she was the one to tell us to sit and wait and then no where to be seen. Finally someone professional and extremely courteous walked by ... the service manager. He quickly apologized for our wait, and brought along Daniel Claudio. I am SOOOOOOOOOOOooooO thankful he did. Danny was professional, kind, humble, hard-working, and just all the way a pleasure to work with. He represented Carmax the way it should be. He took the details of what we were looking for and walked us around to cars that would fit our needs. The second car (nissan pathfinder) was a recommendation from him... and that was the car we bought. Danny if you're reading this... THANK YOU! You're such a great employee and that deserves recognition.

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.

Alex Fragoso was a really helpful, kind, and understanding person I would definitely recommend going to him for any car purchase!

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.

Alex Fragoso has helped me for the past 10 years and I will definitely keep coming to him! I just bought another vehicle and as always he was super kind and super helpful!

Does anybody else’s truck just sit there after you put it drive? I have to bump the accelerator to have it go into gear. ??????????????????????????????????????????? ?????????????

Brandon Brayboy goes up and beyond to make sure every detail of your buying experience is as it should be. I highly recommend Rick Hendricks and Brandon to walk you through your next car purchase.

My 2022 GMC Sierra 3.0 Duramax pickup truck is a good truck. I work on a farm and I also drive an hour to see my girlfriend. For the farm, it has excellent towing capability and for the hour long drive to go see my girlfriend, depending on the weather for traveling, I can get up to 35 miles to the gallon!

I had a great buying experience with Charles, felt no pressure, and walked out with the exact car I came in to buy. It was a very quick process. Thanks

Excellent comfort and very good truck, it is very functional in every way, both for business and for personal, it can be said that I have the 2.7L Turbo engine and I can move up to 11500Lbs already checked by me

Exceptional! Their customer service is always spectacular! Team members are sincere, courtesy and always provide the best recommendation to fit the need of service at that time. I've recommended Rick Hendrick GMC Buick of Duluth, GA to several friends and relatives.

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.

Ricardo was wonderful to deal with and helped me find the vehicle for me! I would recommend him to anyone in the market for a new or used car.

Waiting for the Refreshed 2022 AT4 was well worth it! With all the manufacturing issues today, building and shipping was slow, but understandable. Love the truck and the features! Fit is perfect and quality is #1. Pricing was too high but all vehicles are running this way. You get what you pay for and this truck is perfect! I have owned many trucks and this by far is the best. The latest features are beyond most other makes and GM has thought this truck through from front to rear.

Hennessy Porsche set the bar across the board for a perfect customer experience. From the moment I reached out with a brief inquiry, Gene McClure was responsive, extremely knowledgeable, not only about the vehicle itself, but in walking me through the entire process. It could not have been more seamless and made the process very pleasant. Their attention to detail and my satisfaction was unparalleled- going above and beyond in every aspect!

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

Kelsey Blair in the Service Department was great to work with and got our truck serviced on schedule while we waited. I would recommend her.

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.
