Used GMC trucks for sale near Live Oak, TX

I purchased my first truck from Red McCombs and now my second. Great selection of vehicles to chose from. Talented people to work with. Thanks for the opportunity and when I’m in the market again I will look to Red McCombs first.

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.

This is my 2nd vehicle purchase from Seguin Chevrolet. I will continue to keep coming back here and especially to my salesman Arnold Guerra. He is the best and goes above and beyond for his customers. If anyone is in need for a vehicle come to Seguin Chevrolet and ask for Arnold Guerra. The whole Seguin Dealership treats you good and like family.

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.

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 purchased my 2021 Santa Fe Calligraphy in February of 2021. J.T. was my sales person. I cannot recommend J.T. and this dealership enough. My vehicle is currently in the shop after my son had a minor accident. The service department did not have any loaner vehicles available so I decided to call J.T and see if there was anyway he could help. Not only did he remember me from 2 years ago but he worked with Sam to provide me with a loaner from the sales department. I need to also mention that Sam has helped me in the past as well. I am so impressed with the quality of service this dealership provides. They don't forget about you once the papers are signed and you drive off the lot. They are there for you, whether it's J.T or Sam in sales, or Justin in service who has even offered to drive me home after he was off work, I couldn't have asked for a better group of people to give my business to. Thank you guys!!!

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

Best experience my wife and I have had at a car dealership. Did not want to hassle with the games some dealerships play. We lucked out and as we walked in was greeted by the Manager Joe Lopez who took time to ask us if we needed help. He is extremely professional and knows how to work with people. He is transparent and open to questions. Fastest time we have spent buying a new truck. Drove in from South Texas and was out with new 2025 Ford Maverick in less than two hours. Great price and have found the Maverick all it is claimed to be. We highly recommend anyone looking for a new vehicle to stop at Mac Haiks first and ask for Joe Lopez Leroy and Alicia

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.

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 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!

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 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. :)

First off I gotta say I?m over the moon with my new king ranch! Maverick was amazing and very very helpful. He didn?t treat this like it was just another sale and genuinely went above and beyond to make sure I got the best! I will definitely being going to him and autonation for sure!

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...

Jose was assigned to help me. He was very helpful and knowledgeable. I very much wanted to do business with him but they didn't have the exact car I was looking for.

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.

Friendly staff, clear explanations, and a fantastic repair. Communication is great! John is a great service manager!

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!

Hello Gillman, I had to bring my Honda Odyssey to get service plus an oil change. William Franks was my service technician, he explained what to expect and how long it would take. I appreciate William Franks and his great attitude. He has such awesome customer service skills, communication and has the knowledge of Gillman's policies. After my car was ready he explained everything to me that was done and what will need servicing at a later date. Thank You William Franks Sgm

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.

Since buying my 1500 Sierra in November 2021 during the chip shortage from a different dealer 4 hours from my house, I've always taken it to Ancira GMC in Boerne. At 119,000 miles now, it runs great, and I have to give credit to the guys there for being great at what they do.

I have a 2023 GMC Sierra 1500 Denali with the 3.0 Diesel engine. I have 20,000 miles on it at the time of writing this. Never owned a diesel before and now i don't think i will own another one without it. I LOVE the engine in this truck. Only complaint would be that it likes DEF fluid while towing so pick up some extra DEF before you head out to tow something. Put about 8K miles on it this summer without adding any DEF fluid. seems to use a little more in the winter or when towing. Very quiet for a deisel and the fuel economy is awesome. Driving 70 mph down the freeway this truck gets about 30mpg, Drive 55mph on regular highways and this truck gets almost 40mpg. All around driving for me is about 26mpg. I used to fill up twice a week with my gas motor and now only once a week. Wireless Apple Carplay works great and the voice texting and mapping is a big plus. I also have the new SuperCruise feature which is awesome. Get on the freeway and set the supercruise on and the truck drives itself until i get to my exit (about 28 miles from home to work). Bose stereo is out of this world and all the storage is great to. I have a swingout bed toolbox, aluminum roll up tonneau cover, Lighted black GMC front emblem, Gloss Black 22" wheels, All Black decals and my dual exhaust bezels are black as well. I rotate the tires and change the oil every 5,000 miles. Couldn't ask for a better truck. Might get the ultimate next time as that has the messaging seats which i kinda wish I had.

Walter was great. Helped guide us and explain everything to us. Walter was very understanding of our situation and highly recommend.

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.

Robert was great and took care of me right away, siento his afternoon to show me a truck I was interested. Came in and 2 hours later left in a nice truck.

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.

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.

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.

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

My GMC Sierra is the best ride I have had in all the years that I have been driving. I started driving in 1977. I love my new Sierra.

If you’re shopping for a car Diamond Motors is the place for you, ask for Rick the entire staff is friendly down to the mechanic . They genuinely help you get into the vehicle you desire not just something to get you off the lot. Rick helped me out prior to me even visiting the lot , he let me know what he could do for me before I came so no time wasted. I sincerely recommend them over a lot of these other places who just want the sale , Diamond Motors cares.

The truck has more features than I need. It is quiet and comfortable. it has plenty of power to pull a work trailer. Overall a nice truck

Easy purchase walked me through showed me trucks compared and gave me.prices the ones I was looking at showed the difference between the trunks
