Used GMC Sierra 1500 trucks for sale near Morton, IL

Didn't buy a vehicle from Heller but they were very attentive to my inquiries about a vehicle.

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.

Recently bought a new chevy trax. Tyler was very helpful and the whole process was very quick. This is the fourth car i have bought from them and the customer service has always been great

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

Uftring's in Washington is by far the best dealership around, only place I will ever let take care of me, they care! GREAT people! Nick C in Sales, and service dept.

Am I the only one that has had the instrument panel completely fail? Mine did YEARS ago. So why is my reliability rating 5? The computer still works, I know how fast I'm going, the Miles remaining on the fuel economy is accurate, and it runs. Everyday. Replaced one hub and bearing, water pump, starter, ignition. A/C doesn't work, but I've got windows (which work if you know exactly where to push the button.) Oh, and the Engine light is always on, because the throttle body really needs a thorough cleaning or replacing. Motor and transmission have been crazy reliable for 20 years on truck bought new October '0 3. Nothing a few hundred dollars wouldn't fix. Though there are several of those, they don't keep me from getting from A to B.

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!

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.

Got the duramax diesel and getting 24 city and 32 highway is very good. Truck drives nice and is very comfortable. My 2 issues with this truck is the backup camera at night is useless (very dark) and interior lighting is not very good. You would have thought a 78k truck would have footwell lights, but it doesn’t.

Anthony Krizman helped me get into a new 4xe and was great to work with. I really appreciated his knowledge related to the Wrangler, his positive approach, and genuine interest in my experience. Everyone at the dealership was kind and they even delivered the vehicle to my home. Highly recommend this team!

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.

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 a 2023 GMC Sierra 1500 Denali with the 3.0 Diesel engine. I have 20,000 miles on it at the time of writing this. Never owned a diesel before and now i don't think i will own another one without it. I LOVE the engine in this truck. Only complaint would be that it likes DEF fluid while towing so pick up some extra DEF before you head out to tow something. Put about 8K miles on it this summer without adding any DEF fluid. seems to use a little more in the winter or when towing. Very quiet for a deisel and the fuel economy is awesome. Driving 70 mph down the freeway this truck gets about 30mpg, Drive 55mph on regular highways and this truck gets almost 40mpg. All around driving for me is about 26mpg. I used to fill up twice a week with my gas motor and now only once a week. Wireless Apple Carplay works great and the voice texting and mapping is a big plus. I also have the new SuperCruise feature which is awesome. Get on the freeway and set the supercruise on and the truck drives itself until i get to my exit (about 28 miles from home to work). Bose stereo is out of this world and all the storage is great to. I have a swingout bed toolbox, aluminum roll up tonneau cover, Lighted black GMC front emblem, Gloss Black 22" wheels, All Black decals and my dual exhaust bezels are black as well. I rotate the tires and change the oil every 5,000 miles. Couldn't ask for a better truck. Might get the ultimate next time as that has the messaging seats which i kinda wish I had.

He gave great service. He was Personable and had a good knowledge of the vehicles.

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.

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

Awesome experience, Cliff was the guy that helped me purchase the car, super nice guy

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.

I was shopping online Black Friday week and the big cities had all kinds of specials with fine print and ‘select vehicles’ . I wasn’t sure I wanted to deal with a fast paced dealer where I was just a number. I saw a 2017 Lincoln online in Chillicothe so I sent a request for information. Jeff responded right away and provided me with the service information, Carfax, and brochure. I made the 45 miles drive and was the best decision I could have made. It was a great experience. I was very comfortable with Jeff and Chase. I would highly recommend shopping here for a new or used car. Honest and trustworthy people. I will buy my next vehicle from Riverside Chevrolet.

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.

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.

The service advisor explained service options clearly. And made sure work is completed on time as promised

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?

Austin is a great salesman. Very caring and worked hard on getting us a good deal. The finance dept was good too. It was a quick process.

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 service, good experience Tobe did a good job helping me! Thank you!! Good cars

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.

Sarah helped me get my first car. She was so nice and very knowledgeable about the car. She’s amazing at what she does. I will definitely be coming

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

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.

Car is awesome. Super clean car. Great deal. Service team was amazing. Third car we bought.

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

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.
