Used GMC cars for sale near Powder Springs, GA under $1,000,000

Andres was great and very helpful. Although we didn't purchase we would definitely work with him again. We highly recommend him. He's honest and not pushy.

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

Very nice and knowledgeable one of the best experience I’ve ever had at a dealership, hands-down

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!

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 love my Acadia Denali. It is fully loaded with anything you can think of.I love the V6 engine and how smooth it drives and rides

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.

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.

I have enjoyed my vehicle. It is comfortable and drives very well. I like the color also. It is very roomy, takes off fast and the safety features are very beneficial.

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

This is a luxury suv with plenty of room. I'm still learning the features. It is a smooth ride with a great interior. Great for towing a popup camper.

Read many reviews and researched this vehicle and that helped me decide on this vehicle. Traded in a older suburban for this updated Yukon. Look forward to driving 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!

Took in to fix light coming on re: Anti-lock brakes and Traction control. Didn't realize it was still under warranty, but was informed it was. They also identified a problem with the battery and replaced it under warranty as well. Parts were not in stock, so I was given a loaner at no charge. Also had some 30,000 mile maintenance done on the car. Staff was pleasant and knowledgeable.

This Yukon XL has exceeded our expectations. We upgraded from a 2014 XL and it's like apples and oranges. From a size standpoint, the new design allows my 6'6 son to sit in the 3rd row. Not possible on the 2014 xl. Also, they have upgraded all of the finishes and with the new 10 speed tranny the XL drives and feels amazing. We also opted for the 3.0 diesel as that's what was available. We didn't even test drive one as they are hard to find - but man are we happy with the engine, gas mileage, and just how quiet it is. In city driving we're getting about 22 mpg, and then on highway expect to get about 27. Safety features and heads up display all work great. And, the sunroof thing is amazingly huge. Well done GMC and I highly recommend the Yukon XL to anyone that needs to move people in comfort. :)

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!

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

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.

Perfectly satisfied with their service. I have been using John Thornton and their predecessor dealership at this location for over 25 years. I have never had an issue, and I trust their advice about my service needs and their honesty in recommending when a service is not necessary. Their service department is a factor in why I buy my GM vehicles from them.R

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.

Great Experience overall. Great deal. No pressure. Business done the right way. I am a repeat customer who drove over 2 hours away. Highly recommended.

Just purchased this vehicle a little over a month ago. Love the ride, the comfort of the seats, and, the body style. My only complaint is that it drifts to the right and the steering wheel is several degrees to the left after two trips to the dealer where we purchased it. I will probably have to pay to take it to a known, excellent alignment shop.

I ended up going another route but the interaction I did have with them was positive!

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.

It was a smooth and fair deal ! I?m very happy !!! Thanks to Jake Dodson , Mike Conners , and Luke Darby !!! Everyone was very friendly , honest and was not pushy in any way ! Above board honesty and no high pressure ! I loved my experience John Thornton GMC BUICK CADILLAC !

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.

Great experience! Would highly recommend! Looking forward to my next purchase. Easy from beginning to end! Nathan was very professional and very experienced. Perfect Transaction!

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 love the Yukon. It needs a few censors changed out but it drives so smooth. Very glad we made the choice to purchase it
