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.

Wonderful people. Kind & very knowledgble. Would recommend them to anybody.

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!

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.

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.

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.

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

I wanted to purchase a new vehicle and Terry was the sales man who also sold my mom a car his kindness and understanding made me me feel comfortable. His customer service was spectacular. The finance person was also so kind. I will recommend this dealership to others. They know how to make their customers feel valued.

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.

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.

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.

Great dealership from top to bottom ! I will always use them for all my automotive needs.

The dealership is awesome great people . I didn’t have to do a thing every thing was done by the comfort of my own home. I would recommend this dealership to anyone looking to purchase a car !

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.

Brad is always great to work with. The dealership is clean and everybody is friendly. The guys were prompt getting my alignment done and checking for any recalls.

The Dealership was great to work with from my initial contact through the buying process. They took about a hour training me on all the features of the car. Their follow-up asking me how I like was an added touch.

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!

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 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!
