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

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.

GMC Diesel Canyon AT4. I've had this truck for a year-11,000 miles. I love it. The Denali and Elevation trim looked like junk. The AT4 can't compete with the Tacoma off road but, It holds it's own off road. The Diesel pulls like a beast and the exhuast brake, on all the moutain passes I drive, is worth it's wieght in Gold. I trailer the max. capacity regularly and it's smooth sailing. I traded in my 2500HD Silverado with the vortec 6.0 for this big, little truck. Best decision I've made in a while. I had this truck on order for 8 months and Gm never accepted the order. I finally found exactly what I ordered, just off the truck that morning that I called. 1300 miles away, I jumped on a plane to go get it. Crying shame GMC discontinued the diesel. The extra $ per gallon right now is easily washed by the increase in mileage, 32+ higway, 19 trallering almost 8000 #'s. I wouldn't want the truck without it. Wouldn't want the Elevation or Denali. Diesel AT4 is the truck. I'll keep it the rest of my life barring accident. I'm sure I can get 40 years out of this truck doing 10-12k a year. The regeneration of the exhaust has never come up but, I only do a little round town driving. Most of my miles are highway and hauling a load. I've heard horror stories about regen. from city folk, commuters... You get what you aim for. If you've given it a lot of thought and the diesel AT4 seems right for you, you won't be disappointed. Good luck finding one. GM - You've a winner here. don't let it get away. Ps. Cars.com doesn't have a choice of how I use this truck for WORK. And wouldn't let me submit this review without selecting one of thier 3 inadequate choices. So, I selected having fun cause I believe everything should be but, this is my WORK TRUCK!

I came from Columbia SC to look at a Jeep Sahara I saw online. Greg greeted us at the door and got us into a test drive and then purchasing the vehicle without any issues. He was friendly, efficient, and made my car buying experience a breeze. I would recommend ALM Marietta to friends and family, and ask for Greg!!!

Jason went up above and beyond to help me! You’re a rock star ⭐️. Thanks!

I love my new Hummer, I have had it 2 weeks now and it’s an Amazing vehicle. Looks great and is a lot of fun to drive. I love that I can take the 4 tops off and it’s a convertible suv. So far so good with no problems. It charges overnight and is ready to go. I would highly recommend.

I didn't buy anything from them but they seem to be and excellent dealership.

This was an excellent choice. I really appreciate the patience of the dealership working with me. I think, thought, and over thought this purchase trying to look at every possible angle of why get this vehicle. They had no pressure to buy. They answered any and all questions. They kept offering water/snacks and other amenities for comfort. But no pushy pressure. Patience should be in their title. It was a better experience than I’ve had at other dealerships. Final choice was the iD.4 which they explained everything up front and worked with me to iron out a deal. I tried to look for clues to them being shady or sneaky but it wasn’t there. I feel good about my purchase and would highly recommend them to others. Well done.

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.

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.

great styling and interior. nice features and acceptable performance. overall my Denali is a superior product to similar vehicles. I would recommend this GMC Acadia.

I was very pleased with the service department. Everyone was very helpful and professional. I went there a long time ago and decided to go back. I am glad that I did! I will also recommend them to others. Mr. Golden was very nice and helpful!

Thank you Radi for your help! Radi is always professional and friendly. Whenever I come here and makes sure that everything is done with quality and efficiency. This is 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!

I enjoy coming to buick they are really polite, and make you feel very comfortable. I have been telling people all about them, and I'm even recommended family to go buy a car

I fell in love with my GMC Terrain when I test drove it and have not lost that loving feeling! I have received tons of compliments on it.

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.

The salesman was wonderful, fast, smooth process great experience. Finance processes quick and easy can?t say enough about them. I would definitely purchase from this dealership again.

The Yukon checked all of my needs, I have plenty of room for my children and my Great Danes. I enjoy driving the Yukon and how it handles, overall love this vehicle!

The facility was being remodeled. Enjoyed working with G and Jon. Got a great car at a good price. It was worth driving two hours.

We drove two states over to McKenzie Buick GMC in Milton, FL to meet with Nick and make a purchase on our new Yukon Denali. Customer service was top notch. We were going for their 2019 Yukon Denali to replace a 2008 Tahoe LTZ. We are very pleased with the vehicle. The upgrades are wonderful. Love the cooling seats, the wifi, the HUD and even days after our purchase they have reached out to check on how we were and mailed us a small gift that meant so much. We will definitely use them again if they ever have what we’re looking for on a future purchase. - Brandon Howell 2019 Yukon Denali

I have purchased a number of vehicles from John Thornton Chevrolet and one from John Thornton Cadillac/GMC and have had great experiences in every case. They are the only dealership I use for service for my Georgia based cars.

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

Every one was pleasant but the truck I was interested in was sold. I looked around at some cars and trucks and left

GMC Canyon Denali with the 2.7 Duramax diesel is a loaded power house with great fuel economy. 4x4 has a towing capacity of 7000 pounds, the best in class. 31 MPG on the highway! Previously owned a Tacoma but it would not pull our travel trailer with the V-6. Highly recommend the Canyon diesel, if you can find one!

A smiling face met us at the front door and that set the tone for the rest of our visit. Everyone we encountered was patient, helpful, and genuinely nice. Great experience.

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!

Grant, Cody and Jeremiah were great. Years ago I had a horrible experience at this dealership but todays experience was awesome. They each took very good care of me and made my buying experience memorable. With this team I would purchase from them again.

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 was totally satisfied with buying a car at Nalley Toyota Roswell on September 26, 2025. The process actually exceeded my expectations and I recommend to anyone looking to buy a car to definitely try them first. Great job Titus, Brandyn and Arnold Harrison!

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.

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

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.

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 our new GMC Terrain… We had an awesome experience buying our car. The car was better than what I thought it would be!! Inside, It has great space.
