Used GMC trucks for sale near O'Fallon, MO

Working with Trent and the staff at Dave Mungenast was easier than I had imagined. While looking at vehicles all day, we were exhausted and ready to give up. Finally, after visiting many car dealerships, we found one at Dave Mungenast. Thank you Trent and staff that stayed after hours to help us finalize our purchase.

I bought this after going to the dealer just to look at colors. I had a 2016 Chevy 1500 LTZ that I loved. There was my down payment and took this Denali home. Only 2 options. Paint and moonroof. I thought my chevy with 3.42 gears was quick. This one goes with 3.23's. The ride is great. Fit and finish are perfect. My only complaint is this Bose/Apple play radio is not what the 2016 Bose was.

what a great dealership. there was no selling, they educated me. I know what I wanted almost and they filled the gaps. Every time I go in there I get treated as part of the team

Any reviews on this vehicle is not correct. We are first owners and it’s been an excellent truck. We hate to see it go !

Great sales man. Very nice car. This is the 6th auto we’ve bought from Lou Fuzs

2024 GMC sierra 1500 duramax 3.0 is great truck. Great ride and great MPG. 100% recommend to any prospective buyer. Love the truck and how it perform.

I would like to thank Andre Branch for the excellent service I received during the purchase of my Atlas Cross Sport. This is my first SUV purchase and I love it. Thank you Andre for knowing exactly what I needed. I we continue to support him. Thanks, Vanessa Chambers Browley

Overall I am very happy with my new Truck. GMC however needs to address their software glitch where the display screen intermittently stops working or the audio cuts in and out. I keep hearing a software update is being worked on but that was a while ago?

We had the pleasure of working with Billy Willis. He was so knowledgeable and placed zero pressure on us. It was by far the easiest experience we’ve had. We couldn’t be happier with our 2022 Tucson or with the service we received from Billy!

This truck has a jerk when changing gears sometimes. I enjoy the truck overall easy to handle and comfortable. Drive with ease sight is good when driving.

Great to work with. The access and style of the location are very weird, but buying process went smoothly. Negotiation was fair, and the F&I office experience went great also-no pressure.

My 2022 GMC Sierra 3.0 Duramax pickup truck is a good truck. I work on a farm and I also drive an hour to see my girlfriend. For the farm, it has excellent towing capability and for the hour long drive to go see my girlfriend, depending on the weather for traveling, I can get up to 35 miles to the gallon!

Excellent service, fast process, and very friendly staff. Truly a great experience for a new buyer. I do recommend Angie Flamn!

I have the 1500 double cab with standard bed. The reason I have this vehicle is I really like the 6.5 foot bed. The crew cab with same bed is just too long. The things I dislike about this model is that it only comes in the SLE model. For the 2025 that means the external mirrors do NOT have a power fold in and it does not have a seat memory for more that one driver. The power fold in for the mirrors is extremely important to me.

Everyone at the dealership was amazing! They answered all of my questions, made me feel comfortable, and confident with everything! I definitely recommend this dealership to anyone looking for a used or new car.

Good afternoon everyone, yes, I’m a lady and I’m an owner of a 2017 GMC Sierra 1500 Denali, it has a V8 motor fully loaded sunroof & also it has heated seats & steering wheel for the cold winter months & in those hot summer months you have A/C seats nothing better than that am I correct? It’s been times like that wouldnt trade for the world!! So for all you ladies who think BIG TRUCKS are just for men, go out there & buy one have them put on some electronic slide in/out rails & go out & show the shows the boss!! lol 😄 I’m out looking for a new one now either a 2500/3500 pearl white

This Service Department saved my sanity. I had an issue on a new Ford Focus that no other service department in area could even locate, tried 2 other service departments including original dealer car was purchased from. They found it and fixed it in 2 days.

I purchased a new 2019 SLT with the X1 package. It has the Red Quartz Tintcoat paint. I usually never leave reviews, but honestly this is the most comfortable, nicest loking truck I've owned , and I've ownwd alot of them. The only issues I've had was the brake software was flawed, took it to the dealer on recall and they installed a new software patch, Other then that I love the styling, performance and the interior is very nice. No regrets

Good job as usual! Thats all I have to say so I am wasting time now!!!!!!!!!!

Waiting for the Refreshed 2022 AT4 was well worth it! With all the manufacturing issues today, building and shipping was slow, but understandable. Love the truck and the features! Fit is perfect and quality is #1. Pricing was too high but all vehicles are running this way. You get what you pay for and this truck is perfect! I have owned many trucks and this by far is the best. The latest features are beyond most other makes and GM has thought this truck through from front to rear.

Wonderful staff, easy to work with. Everyone was very knowledgeable and was able to answer all of my questions and concerns through the entire process.

Looked at more expensive truck with less options, bought the GMC SIERRA AT4 Turbo Diesel 6. I now only put fuel im once a month. And long distance trips are easier due to better fuel economy. One of my best investments ever.

Best experience I've ever had buying a car. Great people to work with. Bob Reasoner and Cameron Brodeaux were great to work with. I will definitely buy from them again.

Great service dept, helpful. Sales was helpful in locating the car I have been looking for. Would/will shop atCarMax again. They make it easy and I appreciate the no pressure sales.

Great Place. Nicholas had such good customer service, Thank you. These guys know what they are doing in a friendly relaxed way. Not only the service is expert and fast, price is fair. They take time to educate you. A Friend recommended them to me, and I am passing this along. Thanks

I needed a new pickup and while I wanted a Ford F150 I could not find one set up how I wanted. When I did the Ford dealers didn't want to give what I felt my trade in was worth. I got what I wanted and got a great deal on a 2024 GMC Sierra 1500 Elevation. It is even set up better than the F150's I was looking for and at a better price. I'm very happy with my purchase.

Went to look at a Rav 4. IT greeted me and asked what options were important to me. He answered my questions and explained everything to me. The financing part was painless. IT set up my phone for me and explained all the features of the car and showed me how they work. I did not feel pressure and the entire experience only took about 2 1/2 hours. I hope that my service experience goes as well.

2021 GMC sierra 1500, 5.3, crew cab 4x4, 21000 miles. brakepad monitor lites up. dealership says needs brakes and rotors in back. one mo. on warranty. our rural roads dirty up the monitor. Needs new monitor. brakes look great to me. No noises. dealer says parts on order GM strike. Can't replace myself cause of computer...

My experience was outstanding with Mathis Motors and their sales team. The salesman Jacob was incredibly responsive and knowledgeable. He responded nearly immediately and was able to work the deal in the moment. We were able to set it all up in 30 minutes or less. The SUV is exactly as described and was cleaner than any used vehicle and most new vehicles I’ve ever bought. I appreciate all they did. I would and will give them my business again.

Smooth ride strong motor decent gas mileage inside cab is loaded and very tastefully done along w easy access to knobs. Plenty of room. In back seat ! Aclassy looking Truck with a tacky looking owner!!

The truck Handel's well. Sluggish when in second gear and the transmission thumps mostly when shifting down. Started about 40k. The ride is nice and comfy.

Like this dealer for getting my Escape serviced.......they are really helpful

I bought my 2020 with 36k miles a couple of years ago and I now have 60k miles of trouble free very enjoyable driving. It was expensive, but worth every penny. The ride is so quiet and comfortable my wife and I prefer traveling in it instead of our 2018 Acura MDX which we also love. The 5.3 V8 has plenty of power and towing ability. The multi-function tail gate is genius, I hope to never be without one again. We so enjoy all the bells and whistles, especially the wireless phone charger. So glad I bought this truck!

The staff was very friendly and helpful. I would recommend them to my friends and family. The location is very convenient and the prices are reasonable.

I've owned this GMC Sierra 1500 All Terrain since it was 8 months old. With the exception of two warranty issues (failing power brake vacuum pump and transmission electrical harness), I have been totally happy with this truck. Up until now, my 1996 Chevrolet K1500 Silverado with it's 5.7L Vortec engine was my favorite truck of all time, this GMC (5.3L LS engine, 8 speed automatice) has earned the top spot now of my all time favorite truck. It is comfortable to drive, and runs as good as the day I bought it over 5+ years ago. I've got 71.5K miles on it. My biggest issue is I wished it had the 6.2L engine for better towing capabilities. Other than that ... love this truck.
