New and used 2025 GMC Sierra 2500 trucks for sale near Flower Mound, TX

Great dealership! Very professional and Mike went out of his way to make sure we reviewed all the cars we wanted to see.

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.

The best experience buying a truck. Honest, fair, and no pit bull following you around!

It started in the service department after I arrived in my 2019 GMC Sierra 1500 with 175,000+ miles. There was a problem with the transmission. After consulting with a few service techs, I decided it was time to buy a new truck. They introduced me to Thomas Swink in the sales department. He was very knowledgeable about all the trucks and he was an excellent salesman. Not pushy at all, but knows how to close a deal. Negotiations were quick and easy. I was able to drive away that same day in the new truck.

The salesperson Norman was great to work with. The dealership had the vehicles that I needed. Easy to get in and out with little wasted time. Highly recommend Norman and Hiley GMC

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.

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.

Jeremy was incredible and made the process of buying a new car so easy. When it’s time for a new car, he will be my go to salesman.

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.

I've been going to this dealer for the 6 years I've had my Buick. Mary was outstanding and a great employee. Great experience again!

Robbie, my salesman, was outstanding!! He made it painless and is absolutely customer focused. Pricing was ultra-competitive. Dealership was clean. We will definitely go back.

We just bought a used car from HILEY- Buick- GMC-of-Fort Worth with John Talley. We had shopped extensively and found good deals at 3 different dealerships. Although one of the other dealership's offer was slightly better than Hiley's, we were completely swayed by John's knowledge, experience, and trustworthiness. We liked everyone we met at Hiley, but out of all the salepeople we met at all of the dealers in west Fort Worth. John Talley is the main reason we bought the car we did. And then Ron and Taylor in Finance made us glad John was at Hiley (they give Finance people a good name!}.

Service was very good. It exceeded all expectations, which were very high to start with. I was met right away at my door and was walked through the whole process. Even on the pick up , I was greeted at the door and helped until I left. I apologize for not responding earlier.

I hate singing the service for an intermittent issue likely caused by a computer chip, on board computer or software but it a serious issue when the Adaptive Cruise control just locks the brakes up at cruising speeds over 55 MPH. I am hopeful they will eventually figure out the issue. This time I requested they just deactivate Adaptive Cruise as I?m worried about serious injury. The last time the brakes locked up out of the blue, I almost lost control of the vehicle and it slide sideways almost flipping at 70 MPH.

Great experience from start to finish. Our salesperson, Clayton Haas, was straightforward and efficient, and got us to the price we wanted

They had the vehicle I wanted so it was fast, easy on the paperwork, and I got a good deal. Bruce is an excellent salesperson!

Several sales personal where informative and knowledgeable in customer service. I didn’t purchase a vehicle but will give Vanguard the first choice at sales.

Very good service, and while they were performing the service you could see the inspection that was performed by video. Most places don't show that to the customer.

Nice sales people. Easy to work with, but would not move on the price of the car.

Very good and courteous staff. Had difficulty locating my appointment but all went smoothly afterwards. Picked up my car in no time. It is always washed for me!
