Used GMC Sierra 1500 SLT for sale near O'Fallon, MO

We recently purchased a 2014 Mazda 3 from Lou Fusz Mazda on Lindberg. My husband and I visited every Mazda dealership in the Saint Charles/Saint Louis area. Our salesperson, Chase Winters, was very knowledgeable about the Mazda 3 and was a pleasure to work with. He lets you make up your mind with no pressure to buy. Chase stayed late after the dealership was closed to make sure all the paperwork was completed and the car was cleaned and ready for us. Everyone we dealt with at the dealership was friendly and helpful. We will come back to Lou Fusz and Chase Winters the next time we are in the market for a car.

Great truck to own. The 2023 GMC Sierra Denali with the 6.2L engine delivers excellent power, smooth performance, and a refined driving experience. The ride quality, interior comfort, and overall build quality are outstanding. I have had no issues whatsoever, and it has been a reliable, enjoyable vehicle from day one. I would highly recommend it to anyone looking for a premium full-size truck.

I had an excellent experience working with Rodney Brown. From the very beginning he was knowledgeable, attentive, and genuinely interested in helping me find the right truck. He provided clear, honest recommendations, and I never felt pressured to make a purchase.

Let me start by saying I have the AT4 model with the Duramax 3.0L diesel. I had a 2024 Elevation with the 5.3L V-8 that I bought to pull my 22’ camper. While the Elevation pulled my camper fine it drank the gas like it was on a binge. And with a 26 gallon gas tank it seemed I was filling up every couple of hours. After one trip to Nova Scotia I knew something had to change. I pulled my camper out west to Yellowstone and back through Arizona. It pulled like a champ and fillups were a lot more manageable. Even driving the speed limit out west I still got four to five mpg better than with the gasser. I liked the Elevation but I love the AT4. Way nicer ride and great handling. I get 30 per gallon of diesel on the highway if I drive the speed limit but I got it to tow with. I added a Titian replacement fuel tank so I have 43 gallons instead of the 26 it came with.

Thank you to Saint Charles for my new rogue! AJ was great to work with

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.

Had such a positive experience. Luke LaFond greated me when I came in the door and spent the day working to find me the right car within my budget. He was kind and very patient. I wouldn't hesitate to contact him in 2024 to lease my next car. By the way, I could not be happier with my Kona. It is sharp looking. When going to take care of the payment, Joey also bent over backwards to make me comfortable. Pam Marquitz

I love it the look the interior mine is a red one and it looks so good and it’s my baby and it runs so good and the technology is off the chain

We live on the Illinois side and this was the third vehicle that we have purchased from Bommarito VW. My wife just loves VWs. The pricing and the inventory are just better as well as their Service Dept is just top notch in our opinion. Andre Branch is who we worked with on our last two purchases, which includes our most recent purchase of a 2021 Premium Atlas. Andre is a great guy with an awesome personality. He is not pushy, he is very professional and courteous. Andre just wants to make sure that you have a good experience and help you get what you want. His care for you doesn't just end at the door with the sale, he continues to follow up with you afterwards to make sure that things are going well. We will ask for Andre every time we need to conduct business at BVW. This last experience was our best one yet! Thanks Andre, keep up the Great work! See you next time....

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?

I bought my used vehicle at Sunset. Brad Johnson was an outstanding salesman to work with. No pressure, explained process and took his time. I'm very happy with the entire purchasing experience. Go to Sunset and ask for Brad when you look for your next car.

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

Great staff - great inventory 30k cars in 300 stores in 30 states. No one does it better than AutoNation!

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.

Bob Reason did amazing job with helping buy my Dodge Durango. I drove one car and he could see I wasnt happy with, so I asked if there was anything else in my price range he pointed me two others and when I came back from driving the Durango he knew it was it. Very helpful and pleasant.

Am in disbelief every week at the Gas Pumps. Thou a big truck, mileage per gallons are 18 +. Last week it was 22.8. This week 19.78.

Great truck, solid engine, comfortable, smooth, and it handles great for such a large vehicle. Get one and enjoy miles of roadtrips with all you can tow or haul.

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

We just replaced our 2022 Buick with a 2024 Buick Encore GX. Vivek Abraham is very helpful and does a wonderful job as a sales person. Crystal Mc Elroy is a wonderful sales manager and she is the reason we keep going back for more cars. The entire staff is helpful and we had an easy buy. We do our service at Suntrup Buick GMC too They have been very fair on tires and overall maintenance for our cars over the last 15 years.

I own a 2023 Sierra 1500 Elevation equipped with the 2.7L TurboMax, and it’s been outstanding. It currently has 23,000 flawless miles. I’ll admit, I was skeptical of the 2.7 at first, but I jumped in feet-first and have never looked back. Living in Colorado, I regularly tow a 5,000-pound travel trailer through the Rockies with zero performance issues. The truck pulls confidently, handles grades with ease, and still delivers impressive fuel economy—23–24 mpg on the highway and about 18 mpg in town. I couldn’t be happier with this setup. If there is a negative to mention, that would be that after three years of ownership, the black wheels havent grown on me, and Im beginning to hate em. :) Lastly, the mpg while towing drops to 9mpg which is similar to that of a V8. All said, its been a great truck. :)

Exceptional experience very good price Brian Ries is a excellent salesman had vehicle equipped exactly what were looking for

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.

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!

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.

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!

handles and drives great, the electronics don't always work, mirrors don't always work, spray with wd 40, check engine light, EVAP culprit, auto nation has no luck with this, will drive it till the warrenty expires and its back to ford for me

Work was done on Schedule, actually completed prior to estimated completion time. Both my Service Advisor Jerry and the Tech, came to me afterwards to make sure everything was Satisfactory. Thank You

Great team! I Was a walk-in. Friendly helpful staff - went into look at a Canyon. I found the truck online. Salesman TJ helped with locating the truck and brought it up to the showroom. Even washed it prior to me seeing it ! Great financial staff. Quick and easy!! I Will return in the future for more vehicles.

Mike was very helpful. We weren’t sure what type of SUV we wanted and Mike helped us decide which one was best for us. So far so good.

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

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.

Got transportation to home while repairs were being made with a nice guy. The repair was not as scary as I thought it would be.

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!!

Engine light came on, rough shifting, Adam in Service dept fit my truck in for diagnostics within a week. Tech found bad coil, replaced and repaired, also suggested new wires and battery was needing to be replace really low crank, all work completed and again on the road after 310,000 miles. I have had only good experiences with the service department staff and techs. Sometimes it cost some money but its a machine and if you take care or it, it will last.

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.
