Used GMC Sierra 1500 AT4 for sale near Heath, TX

Mr. Adriano Silva really surprised us with his excellent customer service! Something you don't get to experience very much anymore. I was extremely impressed with his professionalism. He politely approached us and talked to us before we told him what we were looking for, once he knew what we wanted he went straight to finding exactly what we wanted! That place is full of cheerful people and all willing to help you, no rolling eyes when I asked a question, no interruption while I spoke, overall, it was a great experience!

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.

Took my Mini in for a service at Mini of Dallas. They are courteous and friendly. They produce a video informing me of any repairs that are needed, all the while, I sit in a very comfortable lounge with free coffee and snacks

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 !

Best experience I’ve had and I’ve had several in my life. I also had several prior to buying this vehicle. Kariel Nieves was my sales guru. Totally awesome gentleman and knows his stuff. Great attitude and huge knowledge of all things Lexus. Good communicator and worked with me to get my scheduled test drive and had everything ready. A++++++++ I’m sure they have many excellent associates but I’ll only work with Kariel from now on. Top noche.

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 bought my 2020 with 36k miles a couple of years ago and I now have 60k miles of trouble free very enjoyable driving. It was expensive, but worth every penny. The ride is so quiet and comfortable my wife and I prefer traveling in it instead of our 2018 Acura MDX which we also love. The 5.3 V8 has plenty of power and towing ability. The multi-function tail gate is genius, I hope to never be without one again. We so enjoy all the bells and whistles, especially the wireless phone charger. So glad I bought this truck!

First-Class Experience ⭐⭐⭐⭐⭐ I can honestly say this was one of the best car-buying experiences I’ve had. Madi Mustafa took great care of me from the start. He really listened to what I was looking for and helped me find the right vehicle without making me feel pressured at any point. Everything felt relaxed, professional, and straightforward. When it came time for financing, Dylan made the process just as smooth. He explained everything clearly, answered all my questions, and made sure I was comfortable with every step. It was efficient and easy, which I really appreciated. Overall, the experience felt elevated and well handled from beginning to end. If you’re looking for a team that values professionalism and truly takes care of their clients, I highly recommend working with Madi and Dylan.

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.

Good experience in dealing with Kerron at dallas lease returns, would Definitely buy another vehicle from him !

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

Easy purchase experience, would recommend to anyone looking for a new car. Everyone there was friendly and made the whole process as smooth as possible

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. :)

Shout out to Derrick Scott he was my car. He was not pushy at all. He was very, very respectful and fun. It made my car experience, go by smoothly as we know car buying can be stressful. I recommend this establishment as well. Everyone had an upbeat personality. Shop with them you won?t regret. I drove two hours to get to them.

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.

Very responsive, answered all my questions. Vehicle advertised online was exactly as described. Process was easy and accurate. Very pleased overall with my purchase.

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.

This is my third purchase at this dealership, and each time has been an amazing experience. They listen to what I want and have not once talked down to me because I?m a woman. I feel like I?m a valued customer from the moment I step foot inside to purchase or to have my vehicle serviced. This is the only dealership I will go to. Thank you Eldorado Cheverlot!

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!

Nathan always gets us in and out with great service! Quick oil change, tire rotation, and air filter were done. This is the only place to go!

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.

On March 18th 2026 Ray Rodriguez our sales Consulant and Blake our Finance Consulant were both just great, easy to work with, great customer service, friendly and made the buying of our daughter's new car a comfortable and enjoyable experience, thanks to both of you, we will recommend Reliable Chevrolet to friends and neighbors.

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.

Tommy was a very knowledgeable salesman and also patient and not pushy. It was such a breath of fresh air buying a car this time around. Also nice that each of your sales agents have their own desk and space instead of negotiating at an open table. The facility was very clean, updated, and functional. Our finance agent was also patient and answered all my question. He did not rush the process and went out of his way to help us find a good rate. I will be back to your dealership next time in market for a GMC or Buick.

I was very impressed that they had the car prepared for a test drive even with a very short notice. Chuck

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.

I used CarGurus and I discovered my new-to-me 2025 Ram 1500 Limited at El Dorado Motors. I called ahead and Ms. Daniela Lopez helped me out right away. She was friendly, quick, and straight to the point. She gave me all the details I needed and even provided a full out-the-door price breakdown over the phone, which ended up being an incredible deal for a truck with such low miles. I ended up driving about 7 1/2 hours to pick it up, and everything was exactly as she described. No surprises, no gimmicks, and no last-minute changes. The truck was in excellent condition and matched the listing perfectly. They also gave me a blind estimate on my trade before I arrived and honored it without any hassle. The entire process was smooth and honest. My salesman was fantastic. She was professional, not pushy at all, and genuinely easy to work with. From start to finish, the experience was straightforward and stress-free. I was in and out in about an hour. If you’re looking for a dealership that does business the right way, no nonsense and fair pricing, I highly recommend El Dorado Motors.

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.

We were treated very professionally and any issue that we had was handled with respect. Lucky and KP handled the end-to-end dealing, Randy ensured the financial aspects were good to go, and Frank handled any services that we requested.

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?

I found the personnel at international auto to be very friendly and helpful. We did have some issues with our salesperson being out of office and getting someone else to help us when we needed it. The actual car buying process, once we got to that point, was well handled and professional.

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...

Had a great online experience. Fast and easy buying process with fair prices. Salesperson and staff were helpful and not pushy. Would definitely recommend and buy there again.

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.

I recently purchased a 2020 Mercedes G550 from Top Line Auto, and I couldn’t be happier! The car is absolutely phenomenal—every detail exceeds my expectations. The service I received was exceptional, going above and beyond to ensure a seamless experience. If you’re in the market for a vehicle, I highly recommend Top Line Auto. They truly deliver excellence in both cars and customer care!

I purchased pre-owned 2020 1500 SLT in February of this year. The truck rides comfortable and has plenty of room front and rear. My and I both enjoy it. My only drawback is the turn radius (lock to lock). It lacks compared to my wife's 2018 Yukon SLT, or the 2016 Ram I traded in. Have to many times maneuver twice to park it going forward or reverse. Otherwise happy with our purchase.
