New and used 2026 GMC Sierra 1500 Denali trucks for sale near Overland, MO

The customer service at Dave Sinclair Buick was fantastic! They had a lot of work to do on my vehicle. The work was flawless. The level of communication during the whole process was superb. Eric in the auto body shop showed what excellent customer service should look like. I cannot thank them enough for the level of service the team provided.

A little expensive, but comfortable, quiet, smooth ride. Great performance out of the 6.2L and better than expected fuel economy in the low 20s. Outstanding interior and good looking exterior, especially in the Downpour Metallic color. I don’t have 700 miles on it yet and have owned it for 3 weeks. Therefore, I can’t pass judgement yet on the reliability, but so far I am very satisfied. This replaced an 8 year old Ford F150 that served me quite well with only a couple of issues in the 100,000 plus miles.

Walter Washington was excellent. Very nice and kind. I would recommend him to all family and friends.

It was such a good truck honstly the greatest thing I have ever drove in my entire life I am so happy that I have been blessed with this being my first ever car

I always get great customer service from everyone at Laura Buick. My go to guy is David Day. They always do a great job with any issues with my car.

Best kind of dealership. No pressure sales and mindful of your needs as a customer. We will definitely be repeat customers.

Great experience. Jimmy was great and answered all my questions. love my new Yukon XL 2025. I would definitely recommend Jimmy and this dealership to my friends and family.

Nicki was wonderful, I will recommend her to everyone I know that are in the market for buying a vehicle. Jarrod was also fantastic to work with. Both very personable and made the process very pleasant when it had been made dreadful from trying to deal with other salesmen at other dealerships. These 2 were excellent. I've never had a better car buying experience. I'd been to 4 other dealers who wouldn't budge on price for the same vehicle. I was able to drive my brand-new car off the lot for $6000 less than the competitors offered WITHOUT a single haggle!

Gus and his crew were amazing. I bought this pickup off the internet, and they picked me up at the airport and 1 hour and 20 minutes I was headed home.

Very satisfied. Colin went above and beyond to help us. He was so helpful. Very knowledgeable about all the cars we test drove. Would ask for him again next time we are ready to buy.

Wonderful experience! Laura Buick didn?t disappoint as usual! Repeat buyer and will do it again! The staff and facilities are first class! Our salesman Cory Sperry was phenomenal!

Justin was easy to work worth, made buying the 2026 truck quite painless. Very knowledgeable. He was very prompt in returning my phone calls. Would buy from him again.

Bill Erwin was so helpful in our purchasing our new SUV. He had all the answers and helpful attitude to help us make our decision. We have used this dealership for years and have purchased several vehicles from them. The service dept has always been great. Thank you Bill for calling and even following up with us that we were all set up etc. This purchase was handled with ease, no stress. We appreciate Bill and this dealership!

Nikki was extremely professional and knowledgeable about the trucks. The buying experience could not have been easier, and I never left South Carolina! My new Denali Ultimate gets delivered today at 5!

Work was done on Schedule, actually completed prior to estimated completion time. Both my Service Advisor Jerry and the Tech, came to me afterwards to make sure everything was Satisfactory. Thank You
