New and used 2026 Buick Encore GX ST for sale near Green Park, MO

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.

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

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.

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.

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.

Overall good drove over three hours to arrive, pain that policy is they don?t accept checks or certified checks when purchasing outright. Did money transfer before leaving home and waited an hour at dealership for verification of transfer total four hours (ridicules). Other than that process was simple enough.

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

Great service!I was picked up at the airport in a very timely manner.I recommend this dealership to anyone I meet that is looking for a vehicle.

It was a great experience, I purchased the 2020 GMC Canyon Denali from Laura Buick GMC, I love the vehicle and service rendered by the dealership was incredible. They are a great dealership to patronize because they make their customers feel valued.

Justin Scheaffer supported my acquisition of a 2025 GMC Denali truck with total customer care in mind. From finding the exact vehicle I wanted to it delivery, Justin was there, front and center - An Outstanding job; definitely a go-to professional who gets my highest rating!! Thanks Justin - Will stay in touch!

Bruno was awesome and determined to get me the vehicle that I wanted. Which he did. he was selfless and made sure that everything was convenient for me. I highly recommend anyone seeking a new car to go to Bruno.

Our salesman Bruno was the best by far! We didn’t feel pressured to buy a vehicle, but at the same time we felt safe buying a car from him. He was very informative and made sure all our questions were answered. He called a week later to check on the car and let us know if we need any further assistance to reach out. I have recommended my family to go see Bruno at Cardinal Buick!

Total definition of teamwork love it very understanding and will work with you!!!!!! Love my car family

Go to Cardinal Buick/GMC! The staff is amazing and our salesman Bruno was amazing! Professional and understanding of what we came to buy! Love this place! Sent my brother in law to them and he bought a car too! I’m sure we’ll be back to buy our next vehicle too😊😊

This was my second vehicle purchase with Cardinal GMC, and I have to say, the experience this time around was a huge step up, all thanks to Matt Columbo. My first purchase didn?t go as smoothly, but I met Matt when I came back for service, and he immediately stood out. He took the time to notice an issue I was having and actually helped make it right, which left a lasting impression. So when it was time to buy again, I didn?t think twice, I went straight to Matt. He made the entire process easy and stress-free. He was knowledgeable, patient, and genuinely cared about getting me into the right vehicle. I love my new Buick Envision and couldn?t be happier with how everything turned out. If you?re heading to Cardinal, ask for Matt. He really goes the extra mile.
