New and used 2026 Buick Encore GX ST for sale near Valley 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.

Bo is a asset for your dealership with his professional manners of taking care of customer needs when they are purchasing a car to fit their budget of completing a deal of customer satisfaction of driving it off the lot.

I purchased a new Samsung S25. The Google GPS app on the phone would not connect to the GPS display in the Equinox. The Phone store where I purchased the phone could not get it to connect and neither could I. I and others thought possibly GM software was out of date. So, I brought the car to Sapaugh GM. The tech determined the software in Equinox to be the most recent upgrade. And after some troubleshooting decided to problem might be the phone's Google GPS app. He removed the GPS app from the S25 and reloaded it...the result was the GPS is now operational. I appreciate and respect the troubleshooting and repair capability of the Tech which extended past the GM boundary to an associated vendor. I use the GPS and consider it a tool for convenient, safe driving. Thank you Dan McHale

The customer service was great and very polite and easy to work with and talk to about buying my new vehicle . I would definitely recommend them to anyone and everyone

Scheduled Maintenance, arrived on time, service was completed in the time frame given and on the road again.

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.

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.

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!

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!

Best car-buying experience I have ever had in over 50 years of buying automobiles. It was simple, straightforward, honest, no-frills (read no added costs), and the large selection meant that I was able to get exactly what I wanted. Online shopping and negotiating was very easy with no surprises when I reached the dealer to make the purchase.
