Used GMC Sierra 1500 SLT for sale near Plano, TX

David Boyce and George, the finance manager, did a great job, very pleasant and easy experience overall! They were both very detailed and patient during the entire sales process1

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.

Pleasant, cordial, and very courteous. Very informative. Keep me updated. Thanked me for being able to serve me.

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. :)

Nice people will recommend this dealership.The sales associate was very helpful and understanding and cooperative

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.

I had an excellent experience purchasing my new truck, and a huge part of that was thanks to my salesperson, Pedro. From start to finish, Pedro was professional, knowledgeable, and genuinely focused on making sure I was comfortable and confident with my purchase. He took the time to answer all my questions, was transparent throughout the process, and never made me feel pressured. The entire experience was smooth, stress-free, and actually enjoyable—something you don’t always hear when it comes to buying a vehicle. If you’re in the market for a new truck and want someone who truly cares about customer service, ask for Pedro. I highly recommend this dealership and would absolutely come back again.

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

I have purchased several cars in the past few years with kids turning 16 and helping family members. I wanted a Santa Cruz and Clay Cooley has several of the 2023's. I called and spoke to Devaunta Cuba and he said he had the car I saw on Cars.com. I drove down the next day and working with this dealership was pleasant! No high pressure, no hidden added fees, no this price is only if you finance with us and a fair price on my trade in. Overall a very good experience! If you want a Hyundai, this is the place to go first!

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.

Great Experience! Everyone was very nice and helpful from the beginning. The process was smooth, easy and most of all I got what I wanted! Let the team know I am a very satisfied customer!

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!

From the time we walked on the lot to look at their luxury SUVs..we felt welcomed and our sales experience exceeded any other dealership. We ended up buying a 2025 QX80 Luxe Model..absolutely gorgeous car They went as far as bringing us the vehicle when we started the financing process. I can't say enough about the customer service. If you ever decide to buy a luxury vehicle please go to Crest Infinti..you will blown away with the service they provide.

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?

Although I have not purchased a vehicle from this establishment; (yet) I still want to highlight my experience. From the get go, I worked with Jennifer. She was amazing!!! I asked a lot of her with pictures and such, as I live in CT! She got back to me promptly and courteously. Always following up with me to assure I received them. Thanks Jennifer!!

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 !

Bought a car here. After several years I traded it in and bought another. Values were fair on my trade-ins. Vehicles on the website are really the ones they have on the lot. No pressure, no negotiating, huge selection. Paperwork process like normal. I did have to refinance after I left there because the interest rates were steep and I got better deal from credit union. Overall recommend. Had a car accident, will return to Carmax.

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

Oh my Goodness.. I just trade in my last Prius 2021 with 183000 miles for a 2023 Prius with 7500 miles. My Sales Consultante was John Vakili. He was a nice guy and I had all my questions responded. I high recommend.

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.

Adam and the rest of the staff are amazing. Helpful, and very knowledgeable 5 out of 5 stars

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!

A Truly Exceptional Car Buying Experience with Ray Fuentes at Auto Merchant! From start to finish, my experience at Auto Merchant was nothing short of outstanding — and that’s all thanks to Ray Fuentes. Car buying can often be stressful, but Ray made the entire process smooth, transparent, and even enjoyable. From the moment I arrived, Ray greeted me with professionalism and genuine kindness. He took the time to really listen to what I was looking for, answered all my questions thoroughly, and never once made me feel pressured. His deep knowledge of the inventory and the auto industry as a whole gave me complete confidence in my decision. Ray went above and beyond to ensure I got the best deal possible and walked me through every step of the financing and paperwork process with ease. It’s rare to find someone so committed to customer satisfaction — he truly cares about his clients and it shows. I left Auto Merchant not only with a beautiful new car but also with a great sense of trust and gratitude. If you’re in the market for a vehicle, I highly recommend asking for Ray Fuentes. His professionalism, integrity, and exceptional service set a new standard for what a car buying experience should be. Thank you, Ray, and the Auto Merchant team, for making this such a positive and memorable experience!

The buying process was pretty good the make ready part needed some work, we had to wait way to long

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!

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.

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 truck, solid engine, comfortable, smooth, and it handles great for such a large vehicle. Get one and enjoy miles of roadtrips with all you can tow or haul.

Lots of Cars available Easy to maneuver web site prices are reasonable . I did not purchase at this time but would consider I have a later time

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.

The owner and all the salesmen were nice and professional. I worked with Mr. Steve. I will be back once I get my credit handled. They had a very good selection of trucks. Go check them out.

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.

I recently had the pleasure of working with Makhi Bailey at Brandon Tomes McKinney Volkswagen, and I couldn't be more satisfied with the experience. From the moment I walked in, Makhi was attentive, knowledgeable, and genuinely interested in helping me find the perfect car. He took the time to understand my needs and preferences, and his expertise made the entire process smooth and enjoyable. I highly recommend Brandon Tomes and Makhi to anyone looking for a top-notch car buying experience. Thank you for your outstanding service!

Maria Cordova always does an exceptional job taking care of my car while being serviced. I appreciate the timeliness and care she gives to me, valuing my time, and trying to make me a satisfied customer.
