Used GMC Sierra 2500 AT4 for sale near Flower Mound, TX

This has got to be the best auto dealer I have dealt with. I bought a truck from Anthony here and after I had the truck for a month I had a couple problems , he had his mechanic look at it and fix for me , even after I bought as is and he was under no obligation , he still fixed it , you couldn't ask for a better , honest dealer , thank you

One very awesome vehicle. Checks all the boxes you need in a truck and exceeds expectations on quality, performance, and looks great ,too. Love my nre truck.

Had a great experience there hassle free. Jermey Burrell had everything laid out for me when we got there. I would recommend to anyone. Keep up the nice work.

So far so good! This truck is the nicest truck I have ever driven. The stance, ride comfort and options are top notch. I went from a 2023 High Country that was having drive train issues but had all the creature comforts that you would expect in a top of the line truck. With the lack of confidence in that particular models 10 speed transmission issues, it became necessary to reestablish my confidence in my General Motors product.

I love Shottenkirk CDJR Prosper! I have always had a good experience with them. I won't go anywhere else. They are very courteous & friendly. Just love them!

I've owned every other American truck and this is my first GMC. I bought the 2500 HD Texas Edition. I absolutely love this truck. It's everything I could have hoped for and more. It is able to pull my 30' travel trailer with no problems. So now when we go out with our trailer I'll have no worries. The look and feel of the truck is outstanding. The 6.6L gas engine actually gets great gas mileage. It gets about the same as my Ford f150 ecoboost. Probably better on the highway. Looking at about 13 miles in the city and 15 plus on the highway. Definitely got a better truck for the price compared to any other american models with the same characteristic and options.

I had a great experience at Vandergriff! Damian was wonderful and made the experience personal! I will continue to refer him to everyone i know because of his hospitality

This truck is the truck that all others should look up to. It rides great, will tow a house, runs smooth, and gets great fuel economy. The Allison transmission is so smooth. The AT4 looks great too.

GREAT DEALERSHIP BRITTANY IS A PERFECT SALESPERSON MICHAEL KEEP BEING THE PERSON YOU ARE PERFECT..YOUNG CHEVROLET YOU ARE MY DEALERSHIP FOR LIFE.

Jarrett Abel has been my Service Adviser for several years. He always takes care of scheduling my appointments and getting my Chevy P/U serviced. The service department does a terrific job of getting vehicles serviced quickly.

If you want to sit around all day, haggle for a price, have someone go back and forth and talk to “the boss,” and generally have an all-around traditional car buying experience, this dealer is NOT the place for you! These guys have a niche and they know their stuff; you’re not going to get the run-around here because their prices are already competitive. My salesman, Anthony, was fantastic as was Jeremy, the finance manager. If I hadn’t sat around and visited with them both, I could’ve been in and out in an hour. This is how buying a vehicle ought to be.

I paid over $106,000 for this truck with warranty. Do not care much about miles per gal. at that that price range. Just too much truck for me at my age.

All staff are kind and professional. The facility is clean and welcoming. I love the shuttle they offer to take you to and from your home.

Outstanding service in all departments! They are the epitome of the gold standard. I highly recommend

Vary nice people, vary good at helping In explaining about the car,and the price. I was not able to go to get the car do to Family issues.

I bought a 2024 Silverado 2500 HD from Mike Black. Mike made the process as quick and comfortable as possible. Great product knowledge and easy to work with. Responsive and helpful. Would not hesitate doing business with Mike in the future

The dealer reached out to me on a Sunday evening to work with my on my inquiry and had almost all the offer work done by the time I showed up to look at the car the next day. Made it as easy as possible for me!

Service department is top notch..best of the best! Friendly yet professional, capably handled my every concern. Ride to/from my office very nice and appreciated touch!

Love everything about this Duramax Denali except the fuel mileage. 13-14 Mpg tops when not towing. Bought truck cause previous was stolen. Wish I still had my 6.2 High Country!

Iliana was a great sales rep. She was kind and very understanding of what I needed. She acquired to my needs and didn’t make me feel pressure to make any decisions until I was ready. 10/10 experience with Iliana Davila.

Very helpful staff, I had been to 5 other dealerships prior to coming here they had the best prices in DFW, they also allowed me to do my own inspection prior to purchasing along with multiple test drives I really liked there service no pressure in buying much appreciated!

I love my 2021 GMC Denali 2500HD. I have gotten more complements on this truck than any other vehicle that I have owned. I get great highway fuel milage average 19-26mpg,which is great for a heavy duty truck!

Simply Exceptional service once again! They continue to be a renowned dealer who cares about their customers and reputation. Sewell will always have my business for life.

Love my GMC. Owned a Chevy and this absolutely beats it hands down. Never had any issues. Inside is very comfortable and can't imagine driving anything else

The level of care, kindness, and respect that Tyler Reynolds showed to my wife and I was unlike anything we have experienced at any dealership. Every other person of the Sewell staff was no different. I have always heard great things about Sewell dealerships and we were not disappointed. We worked with Matthew Jobe on the finance end and he was fantastic as well. Both Tyler and Matthew from start to finish provided us a true no pressure deal. I’m convinced that Sewell Buick GMC wants what’s best for my family and budget. It almost feels wrong to say that I really enjoyed the car buying experience at a dealership but it’s the truth. I want to make sure and add that the care and help did not stop when I drove off the lot. Tyler and Matthew have answered every question quickly and professionally since we have had the car. All that being said, my family will never buy from another dealership. These two men have made us Sewell customers for life.

Chris Pingel made the car buying experience fast & easy. Had me leaving with a brand new truck! When you go to Hiley GMC, definitely ask for Chris.
