Used GMC Sierra 1500 SLT for sale near Canton, IL

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. :)

Great car buying experience. My salesman Sam Altpeter, and his mangers were very respectfull and everything went smooth and done in a timely manner. Thank you!

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.

Everyone was so courteous and helpful there oil change and tag tire rotation, and they washed my car for me!

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.

Great service while I waited in a clean and comfortable waiting area!

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

Great group of people, easy to work with! Would recommend them to anyone looking to buy a vehicle. One of the best car buying experiences I have had.

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.

Sherry was an absolute pleasure to work with. She made the process seamless!! Thanks again Sherry!!

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

Bought my car from Eric Martin. He did a great job was very friendly and everything. Not a problem at all would definitely buy again with Ray Dennison.

Stong engine and smooth! Highly recommend for familys or someone who likes a smooth truck. Purchased new and have had zero issues since then. Love it!

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!

Awesome experience. Brian Dennison is a great owner that cares about customers experience in sales and service. The building is currently being updated and the facilities are clean. You will be impressed by the all new Ray Dennison GMC in Pekin.

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!!

Great place to buy and service any new Buick or GMC. Cadillac sales knowledge is off the charts

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.

My daughter bought her first car here! And years later, a great place to buy a car.

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 can't express how great the experience I had with Ray Dennison Cadillac, Buick and GMC. Troy Caldwell was amazing. He explained everything, gave me options and was just awesome. I will recommend this dealership to everyone. Thanks again Troy! I LOVE LOVE LOVE MY BRAND NEW BUICK ENCORE!!!!

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

Everytime i go to the service department all my needs are met and if anything needs fixed they tell me. Shane and kevin the only 2 technicians i use at ray dennison have always taken the time to diag and repair our cars the right way the first time will definately keep returning for service.

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.

Very satisfied with my recent purchase from Ray Dennison. My sales rep Logan was a young, ambitious guy who took great care of me the minute I walked in. They gave me a very fair trade in amount on my truck and everyone was very friendly and made sure the whole process was quick and smooth!

all went well and quick service. They even washed my vehicle when it was done! Unexpected but very appreciated.

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.

Its like the people there treat you better than family .and that's what makes me come back.and the quality of service and maintenance of the vehicles that they have on hand and on record really helped me make my decision for the vehicle that I wanted

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.

Richie Geiger Was a good salesman . Helped me with all my needs and was very understanding and helpful and very patient. Would recommend to anyone.

Easy purchase experience, would recommend to anyone looking for a new car. Everyone there was friendly and made the whole process as smooth as possible
