Used GMC Sierra 2500 trucks for sale near O'Fallon, MO

I was very happy with my time dealing with Charles. He had the truck I wanted to test drive ready before I arrived at the dealership. I felt like family. Charles was very, very patient with me the whole time.

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.

The technician was amazing gave me updates along the way I will definitely come back because of him

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.

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.

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!

Awesome your staff is the best I've ever !!! Will always you BELLEMANN its literally the best customer service group I've seen Worth the extra mile to get there!!!

I love how the truck pulls and rides when towing. It will give any driver the confidence to tow anywhere. I haven't had a single issue with it. I love the way it looks and couldn't be happier.

Kenny M. helped me with the purchase and made the entire process very easy. Thank you again for all your help, I love the my new car!

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!

I always dread the car buying process, it’s long and you need to play the game. But Emily listened to my wants and needs. Honored my wishes on certain cars. She worked for me not for what the finance company wanted. Thanks Emily!! For the easiest car buying experience ever!

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

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.

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.

Just the truck I was dreaming. Auto world experience is great on product knowledge high recommend 2500 Hdz Denali truck you won’t regretted price product and drive experience

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.

I've owned my truck for nine years now it is never once let me down. I'm about to put my first set a tires on it and brakes other than that I don't plan on getting rid of it it's never let me down and after reading all the other reviews it makes me realize they don't make them like they used to as they used too!

We started our car shopping experience online due to a negative experience during our last purchase at a different Nissan dealership. We had never done so much online before and weren't sure what to expect. We were matched to Tyler C and when we arrived on the lot for the first time and Tyler greeted us it was as if we were already part of the Bommarito family. The experience could not have been better. When it came time to complete financing we were passed to Greg F who was equally amazing. He took us through the process with such professionalism that we knew we had picked the best team to give our business to. When the day comes that we need another vehicle you can believe we will be calling Tyler, Greg, and the rest of the Bommarito Hazelwood team. Until that day we'll say thanks for exceptional customer service by sending anyone we know looking to purchase a vehicle their way.

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.

Our salesman, Ben Vogt worked with the Sales Manager, Steve Weis to give us acceptable offer for our trade in.

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.

Love this dealership! The new location is wonderful - I send my family here. My brother bought a car, and loves it!

Mark was great to work with, explained all the features and quirks that our car had. Would definitely recommend. Thanks Mark.

Excellent service. Approved immediately. Thank you, Peter, for your help! There are many options to choose from.

I recently purchased a car from this dealership, and I cannot say enough how wonderful the experience was! From the moment I walked in, I was greeted with a warm and friendly welcome that immediately put me at ease. Every step of the process was smooth, straightforward, and stress-free. The customer service here is nothing short of fantastic. The staff was knowledgeable, patient, and truly seemed to care about helping me find the right vehicle. Special thanks to the general manager, Scott, who went above and beyond to make sure everything went as smoothly as possible. He made what can often be a stressful experience feel easy and enjoyable. I would highly recommend this dealership to my family and friends because I know they would have a great experience, just like I did.
