Used 2023 GMC Sierra 1500 trucks for sale near Lancaster, TX

Working with Ethan on my 1st ever online purchase - was the 1st experience everyone wants! He was efficient with communications, but never pushy. He was flexible and open to any questions, while walking me through the process! Friendly, knowledgeable, and great to work with. The financing process with David's help was a breeze! The process was time efficient and pretty flawless. He was on point with communication and very knowledgeable. Still loving my new car 2 months later- it exactly what I wanted and drives like a dream!!!

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. :)

Rusty Wallis is the way to go! Went in just to look and walked out with a brand new car with the help of LUCIANO who is a great salesman. He really took the time and considered staying within our budget ! Couldn’t be more happier with our purchase thank you to Luciano and management for the help!

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!

Great service and no pressure. Thank you and hopefully we’ll be back. David & Stephani Huffman

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 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.

Great customer service from Robert Sherman from beginning to end. Explained the process of what would be done communication was great I felt relieved knowing how long it could take and cost. Great work all around with a Smile.

Does anybody else’s truck just sit there after you put it drive? I have to bump the accelerator to have it go into gear. ??????????????????????????????????????????? ?????????????

Jose the Sales Manager listened to what I wanted and found the vehicle at another dealership and brought it over. Briana in Sales showed me all the features and explained how everything works. She even helped me get the app set up on my phone. David in Finance was so friendly and made the process easy. I have told all my friends how nice everybody was to me and this was really a no-stress day. I love them. I wish I could buy a new vehicle every year so I can go back over and over.

Great experience buying a car! Great staff and great service. Thanks reliable for all you help

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!

Aaron’s assistance in the process was great and we liked the car we purchased. I did not give all 5 stars because EchoPark pushes an obligatory $699 protection plan that should be optional.

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.

Very satisfied with the outcome of our purchase. Salesman Craig Atkin helped us get the vehicle we wanted at a great price. Any issues we had were resolved to our satisfaction

Very professional and made me feel right at home. Bought my son his first big truck today and drove back thru a blizzard. They hurried it thru and done everything possible to get us home safe. Also bought a truck 5,000 under what anyone else was asking! Could not ask for a better bunch of guys!!

For some reason Mark's name is not on the list where it says, "Choose their name," but Mark was so helpful, patient, explained the process clearly and was very professional. I highly recommend him and would work with him and his team again. I would hope for a promotion for him Hyundai. :)

salelady was very nice and answer all my questions . she helped me with getting a great car .

I was in and out what seem like an hour to hour and a half at most and no haggle pricing and with great discounts.

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.

Very professional and satisfying. We changed our mind last minute on the car we wanted and they remained patient until we decided what we wanted. We are very happy customers!
