New and used 2025 GMC Sierra 2500 trucks for sale near Weldon Spring, MO

From the first time I set foot on the Buick car lot, Beau set off a great car search experience for me and my family. Not only was he awesome but everyone I met there was warm, friendly and caring. The O'Fallon Buick GMC not only brought back my faith in a car salesperson but also purchasing at a car dealership. From the salesman to the financial department each person took time to make sure you understood exactly what was happening. Hopefully, I want have to purchase another car for a while, but if so, I know where to go.

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.

Service Advisor, Kevin Gromer, was very helpful and professional. The tech, Ryan Hellrung, worked through lunch to complete the repair that day. Hats off to both of these Lou Fusz employees.

friendly, reliable service, never have had a problem getting an appointment. I drive twenty miles just because of the good service received.

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

As usual, very good service. Chad Boxdorfer was there as soon as I got out of the car. He was very polite and courteous. Got the car serviced and ready to go in the time he told me. Dave H.

Brought my daughter to look at a new car. Put her in touch with Brook Winter. She walked away with a new GMC Arcadia. She is so very happy with her new SUV. She also was so pleased at the service she received from the time we entered the door until we left 3 hours later. We now have 2 Cadillacs and now she has her SUV. Will always recommend to someone looking to buy.

Great Place. Nicholas had such good customer service, Thank you. These guys know what they are doing in a friendly relaxed way. Not only the service is expert and fast, price is fair. They take time to educate you. A Friend recommended them to me, and I am passing this along. Thanks

Always a pleasant experience. I never have any complaints about service or customer service.

After putting off looking for vehicles, as in the past it was usually not a pleasant experience, we stopped at Behlmann GMC. We were fortunate to have been greeted by Doug Johnson. Doug is very knowledgeable and easy to work with. In fact, we ended up buying two vehicles. We recommend anyone thinking about buying to go see Doug.

Everything was great from a service prospective. Took off a star for the 3% credit card fee. Service is not cheap at the dealer and to tack on an extra 3% is unnecessary. In addition I have a GM credit card and to charge an extra 3% at the dealer pretty much makes the card useless. I?ll probably just cancel it

From purchase to first service, no complaints. My purchase was smooth and easy with Nicki, and my service was fast and efficient with Heather! Thank You!

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

The salesman I dealt with, Rob Fulmer is one of the best. Strait forward, tells you how it is without any hidden surprises. He was honest, patient and very professional. He easily addressed all my concerns and questions and I would highly recommend asking for him to be your salesman. He was very quick in responding as I was inquiring about a car out of state and he made everything very easy and simple to understand. Out of the other dealerships I inquired about, it was like night and day. I ended up replacing my engine in my old vehicle, so I didn’t actually buy from here but everything was set up to go I just had to sign. He was honest about out the door pricing and the dealership he works for doesn’t try sneaking ridiculous hidden fees like some of these other places. This review is the least I could do since I pretty much wasted his time. Thanks Rob and sorry again!

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.

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.

Got transportation to home while repairs were being made with a nice guy. The repair was not as scary as I thought it would be.

Easy process. Dmytro was very helpful and accommodating. Follow up was timely. Found the car I wanted online, submitted a request for information, received a call back immediately.
