Used GMC cars for sale near Dunwoody, GA

I have purchased new and used cars before, from different dealerships all over the Atlanta area. A total of 10 counting this one. Plus 2 bikes, but I'm not counting those. I have had absolutely TERRIBLE experiences, and I have had okay experiences. This was, without a doubt the best of them. What made the difference- Sam Rangel. My wife shopped around online and found a van she wanted to look at, and it happened to be at the Hardy Superstore. She went by herself to check it out. She met Sam. Sam was the opposite of what many come to think of when they think of a used car salesman. Sam was very kind and helped her. He listened to her and genuinely desired to help her find what she was looking for. I know most good sales people are like that, but there are some that don't have a customer service quality to them, but Sam does. She never felt pressured. Sam made us feel like he was on our side of things- whether it was the vehicle, the negotiation, the financing, or whatever. He was our representative. I love looking at cars, and investigating them, but absolutely HATE haggling and the actual car buying part. Sitting and waiting forever, going back and forth. Then when you are done, you have to wait for the vehicle to be cleaned and gassed...ugh. Did I say I HATE car buying? So this time, I done the whole deal with Sam through text messaging! A first for me. Whenever I asked for something, Sam replied. Sam's manager, and Finance closer- Mitch Feraco made a great team. And he had the van ready so when we got there, we signed and drove away! So, if you find a vehicle at the Hardy Superstore, or need someone to help you find one, call Sam Rangel- you wont regret it. Tell Sam I sent you, he will take great care of you!

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.

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

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.

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 experience was excellent with Ted. The videos from the technician ere very informative. My son-in-law had a previous car worked on here and also purchased a new one from Ellis GMC.

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.

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.

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

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!

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.

Manny Platero is an excellent service advisor! He was friendly, helpful, and went above and beyond to make sure I was taken care of. The service was great, and I truly appreciate his attention to detail. I will always choose Manny for my service needs

Love ever single thing in this but the auto stop function really annoy the heck out of me I do t really care about the gas mileage cuz if I can spend $70k then I don’t mind couple $$ extra for gas otherwise I would buy a Tesla

Come see Robert for your car needs !! Great great great service!! Fast and easy service

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.

The oil change was performed to a high standard, and the staff were all excellent. I was able to get in and out quickly. They where very helpful

Notes on the multi point stated my vehicle needed a lot of service, but none were explained. The receipt mentioned the rear differential but also not explained.

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.

Had a good buying experience.Trey the salesman was helpfull in my negotiation and ensured my purchase was ready for pickup.Vehicle was as described on the outside,unfortunately the inside had a few more scuffs than I would have wanted,regardless it had nothing to do with the salesman.Vehicle was shipped from another location and is in new condition regardless.

Jeff Williams provided outstanding customer service. He went above and beyond in ensuring my truck was taken care of. He showed personal caring and commitment!

I needed a new pickup and while I wanted a Ford F150 I could not find one set up how I wanted. When I did the Ford dealers didn't want to give what I felt my trade in was worth. I got what I wanted and got a great deal on a 2024 GMC Sierra 1500 Elevation. It is even set up better than the F150's I was looking for and at a better price. I'm very happy with my purchase.

Easy and fast tire install, will be back for future service needs.. Quick, Affordable, Balanced, Tires, Workmanship, Quality.. Aquaman was great to work with, Thanks again!

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?

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!

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.

I have now bought 2 cars from here ! Thomas was amazing. He was very helpful and kind.

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. :)

I can’t say enough about how wonderful the service was. Helpful staff made the process easy, even when buying from out of state. I would definitely recommend Beaver Toyota.

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

Very good workforce at this location. Sales and financing was top notch service oriented. The overall process was smooth and did not require a whole day to complete. Looking forward to buying more cars from them in the future.

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!

Cory and the whole staff were very kind, welcoming, and very informative. I had a wonderful experience. The facility was clean and the snacks were tasty!

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 have bought a few cars from them and have my cars serviced there as well. They are the best! I wouldn?t go anywhere else.

Heather is always very professional and knowledgeable. I trust her opinion and recommendations. She meets the customer needs and makes you feel as, valued customer.

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.
