New and used 2026 GMC Yukon XL for sale near Herculaneum, MO

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!

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.

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!

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!

My daughter purchased a new car from Sapaugh last night and the experience was the best I have had buying a new car. Logan Cash and Rick Murray were great to work with and took the time to explain everything to my daughter. If anyone is looking for a new car, I highly recommend contacting Logan Cash at Sapaugh.

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.

Bought a used Toyota Tundra from Bruno Borda . He was professional and got us in and out quickly. Thank you for the great service!

Mr. Goodman was exceptional. He answered all my questions with a smile nd he was just a pleasant person. Customer service is always great. Im excited

Excellent job at looking after my needs and locating a truck to do what I needed it to do. Went through a few trucks till we found one that met our budget and specific needs.
