Used GMC Sierra 2500 trucks for sale near Marlborough, MO

I bought a 2025 Ford Ranger Lariat. All the all, the process was very easy and quick. Denesha was wonderful to work with and a great salesperson. I recommend contacting her for your next purchase. We arrived in the early evening (around 6:00) to purchase the truck she and David, the finance manager, stayed late to get the paperwork done and get us home with it. They are great people and made us feel very welcome.

This truck is the truck that all others should look up to. It rides great, will tow a house, runs smooth, and gets great fuel economy. The Allison transmission is so smooth. The AT4 looks great too.

This is the 3rd vehicle I have purchased and currently leasing a new vehicle from Sapaugh. Rich Konold is the best sales consultant. He knows the vehicles and can help you match your wants/needs to the best vehicle for you, and get you the lowest price.

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.

Easy to deal with. Texas was very knowledgeable and caring and listened to my needs. Fast easy process highly recommend! Great place to do business!

I paid over $106,000 for this truck with warranty. Do not care much about miles per gal. at that that price range. Just too much truck for me at my age.

Tommy was very helpful and had prompt communication. He followed up and provided additional photos of vehicle.

One very awesome vehicle. Checks all the boxes you need in a truck and exceeds expectations on quality, performance, and looks great ,too. Love my nre truck.

Everyone at Sunset Ford of Waterloo was above and beyond helpful with our purchase. The professionalism was greatly appreciated along with the cleanliness of the dealership.

I love my 2021 GMC Denali 2500HD. I have gotten more complements on this truck than any other vehicle that I have owned. I get great highway fuel milage average 19-26mpg,which is great for a heavy duty truck!

Jeff Reed provided great service. He is attentive to what we want to know and goes the extra step to make sure he provides that. All the people we spoke to were professional and friendly.

Tim was great . The process was easy and fast I was in and out .he got me approved on my first car!

Shawn did a great job working with us to get us the terms we wanted.

I've owned every other American truck and this is my first GMC. I bought the 2500 HD Texas Edition. I absolutely love this truck. It's everything I could have hoped for and more. It is able to pull my 30' travel trailer with no problems. So now when we go out with our trailer I'll have no worries. The look and feel of the truck is outstanding. The 6.6L gas engine actually gets great gas mileage. It gets about the same as my Ford f150 ecoboost. Probably better on the highway. Looking at about 13 miles in the city and 15 plus on the highway. Definitely got a better truck for the price compared to any other american models with the same characteristic and options.

Taking a 12-year-old CTS Sport Wagon to a Cadilllac dealership for service tends to make one brace oneself for the onslaught of potential sales pitch that naturally occurs when an older model comes in for service and the dealership is in the business of selling brand new ones. To my pleasant surprise the approach was quite the opposite and Terry, along with members of the sales staff, all seemed genuinely happy to provide service work without the sales pitch. The work was completed quickly and the car remains the reliable and fun-to-drive car that has been a testament to the make's time-honored claim as "Standard of the World". Even when I mentioned that a new Cadillac might be in the cards someday, the staff was happy to know they were helping keep one of the most iconic models that Cadillac has produced in recent years on the road. Thank you, Terry and the staff who worked diligently to get my car repaired and back to me well within the time frame that had been promised.

This truck is everything I wanted! GMC, 4x4, Lifted, Low milage. It's going to be great for my hunting and 4 wheeling! I love it!

I had the absolute best experience at AutoNation in St. Peters, MO. My salesperson, Anthony Smith, was upfront, knowledgeable, patient, and kind throughout the entire process. He never pushed me into anything—he made sure I was comfortable at every step and even gave me helpful tips on what to look for during a test drive. I later learned Anthony is somewhat of a local celebrity here in St. Louis, and it’s easy to see why. His approach and personality made the whole experience authentic and enjoyable. I also want to recognize Nate, the sales manager, who worked hard on my behalf to lock in the best deal for my situation. He truly went above and beyond to make sure everything lined up in my favor. And finally, Cameron in finance made the paperwork side of things stress-free. He explained warranties and add-ons so clearly that there was no need for pressure—the way he laid everything out spoke for itself. Because of his clarity, I was able to confidently choose what mattered most to me without feeling pushed. Altogether, this was hands-down the best car-buying experience I’ve ever had at a used car dealership. Anthony, Nate, and Cameron earned my trust, and I won’t hesitate to follow Anthony wherever he goes when I’m ready for another vehicle.

ABSOUTELY WOULD RECOMMEND!! JIM, KAYLA & BRETT HAVE ALL BE BEYOND AMAZING TO MY SON & I. PROBABLY, LITERALLY THE BEST CAR DEALERSHIP I HAVE EVER BEEN TO. THEY MADE US FEEL COMFORTABLE AND WORKED BEYOND THEIR DAINLY AND NORMAL SCHEDULE TO STAY LATE AND MAKE SURE I WAS TAKEN CARE OF. MY SON WHO DREADED GOING WITH ME, WAS ACTUALLY HAPPY HE WENT. THESE 3 PEOPLE, I CANNOT SAY ENOUGH ABOUT. THANKS YOU AL SO MUCH FOR EVERYTHING. YOU'RE THE BEST 100%.

Has everything we never knew we needed. Reliable and heavy duty. The bed is so convenient and we didn't have to chose between any options, this truck has it all.

Wonderful truck. Has had zero problems. I am trading for a new one. Truck is all original with no modifications. Truck is in excellent condition.

Everyone was nice and the place was extremely busy. We worked with Nick who was working with 2 sets of customers at the same time, he did a pretty good job of handling both. We test drove a truck and tried to work a deal, but it just did not get down into our price range.

Great experience with Bruno and Columbo when I bought my Denali. I was able to do most everything online and it was very easy and quick at the dealership. I drove 3 1/2 hours for this great deal and I will definitely shop here again.

Love everything about this Duramax Denali except the fuel mileage. 13-14 Mpg tops when not towing. Bought truck cause previous was stolen. Wish I still had my 6.2 High Country!

Everyone has been very conscientious and courteous checking back with me to determine what I want and if I was aware of the age of the vehicle. They also informed me that their service department wanted to work on some issues with the car and that they would let me know what they did and what work they believe still needs to be completed.

Hands down the best buying experience I ever had, Paul Johnson and Frank in Finance were extremely easy to work with, I felt it was going to be a great experience from the moment I walked into the dealership and was greeted. hanks Guys for making it easy!

What a gorgeous truck, runs good, sounds good and has all of the amenities I need although I am looking forward to their next interior upgrade.

Nick Pashos did an amazing job taking the time to make sure I was happy with my purchase. Michael Minner was great in finance with explaining all the details and working with me financially.

Buying a used car from Carl Schaeffer at Nissan autocenter couldn't have been easier, a truly pleasureable experience. Definitely worth the drive to Herculaneum to see the car in person and test drive it. The car was exactly as advertised on cargurus!

I felt they were honest 1st of all. Can't say that about very many dealerships. They gave the best trade-in value on my 2015 Tahoe (by far). I searched Missouri and Illinois for about 8 weeks and Sapaugh was the best experience Hands-Down. My ONLY fault with my whole experience was getting my paper work finished. It was a cash deal with a trade-in. NO financing needed. But it was a holiday weekend (01/02/2026) only one guy doing the paperwork processing instead of two. NOT a giant deal.
