Used GMC Sierra 1500 SLT for sale near Randolph AFB, TX

Excellent experience every time I go. My service rep Lynda and the dealership are the reason I keep going back. I?ve been a faithful customer for more than 5 years.

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. :)

Great dealership to buy a car from. My car buying experience was quick and easy.

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.

Hassle-free buying and excellent customer service. Best online shopping experience. Transparent pricing. San Antonio Buick GMC is the BEST!

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

The team at Auto Nation San Antonio was great! My trade in was handled quickly with a fair price and they fill the tank up on the new purchase. They made it super easy.

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 !

Great experience! Salesman Nate, was superior! We are very pleased with our purchase! Many thanks to Ancira!

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!

The service was good and the financing was excellent overall the visit was good and the staff was very friendly and helping I would go back

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.

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 service, knowledgeable, and helped me get approved. I had a hard time getting approved and the team got it done. Loving my new Mercedes.

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 recently had a truly outstanding experience at the dealership, thanks to the exceptional service provided by Jordan David. He took the time to understand exactly what I was looking for, answered all my questions with patience, and made the entire process feel effortless. His knowledge, honesty, and attention to detail built immediate trust, turning what can often be a stressful experience into an enjoyable one.

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 recently purchased a pre-owned vehicle from Cavender Cadillac in Converse, and I received outstanding service from Antonio Slaughter from start to finish. He made the entire process smooth, stress-free, and enjoyable—from the test drive, to the final purchase, and even the special finishing touches at the end. My car was washed, filled with a full tank of gas, and he even placed my plates on my beautiful new ride before I left the lot. Antonio went above and beyond to ensure I had an exceptional experience, and I truly appreciate his professionalism, patience, and attention to detail. I highly recommend purchasing your next vehicle from the Cavender Cadillac Converse location—and be sure to ask for Antonio Slaughter!

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.

Our service rep is fantastic. He takes care of the details and is professional. Efficient and friendly.

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...

The whole shopping experience was excellent. Benjamin as always was patient showing us several SUV?s. He is very knowledgeable therefore knew what I wanted. We experienced professional and friendly service the whole time we were at Mercedes. Thank you

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.

I had a good experience making a deal with Mr. Arony & Isidro, both have helped me with all the questions I had. I will really recommend them to my friends and relatives who want to purchase a GMC.

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.

John consistently provides exceptional service by attentively listening to our concerns responding with patience and resolving issues efficiently. I will definitely recommend John to my friends and family.

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

Pleasant experience sales person was helpful I?m very knowledgeable about making sure I was comfortable with the car before I left setting up the Bluetooth on star.

My truck has a great appearance, inside and out. It is a pleasure to drive; and rides and performs great. It is the best truck I've ever owned.

I had a great experience. Jacob was very helpful and up front. Both he and Anna the finance manager worked with me to make the process easier. Thanks

This is the nicest truck I have ever owned. Lots of features. Takes a while to learn what all it does but a really enjoyable vehicle.

I was taking care of right away even when I was early, the wait was not terrible. My service advisor was friendly, I would recommend this place again.

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!

I bought a 2023 Tundra TRD OR pickup this past weekend. I drove over 4 hours to make this purchase and everything from my first call to driving off the lot was remarkable! My salesman, Roger S was very personable and took the time to make sure everything was ready when I arrived. I was in and out in less than an hour and back on the road to head home. I would certainly purchase from them again. Great folks at San Marcos Toyota!

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?

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.

This truck is amazing. Turning heads all over as we tour the area. Those riding with is also enjoy the comforts and safety features. Great Buy!
