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

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.

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 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.

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!

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.

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

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.

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.

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.

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!

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.

Thank you, Derek, for setting the gold standard in customer service!

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.

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

My second vehicle from this dealership. My second Buick Enclave and it keeps getting better.
