Used GMC Sierra 1500 SLT for sale near Dunlap, IL

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.

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.

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.

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. :)

The experiences we have with LIghthouse Buick GMC and our salesman Keith Edelman, is ALWAYS top notch!! Honesty, friendliness of everyone who works there is a great reflection on the owners of Lighthouse and how they treat their staff. We wouldn't go anywhere else to purchase or service our GMC vehicles and encourage others to give them (and Keith) a try for a vehicle shopping experience that makes you want to go back, as we do everytime!!

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 !

I live in FL and was searching all over the Southeast and Midwest for a very specific spec of truck that only a few dealers had. After talking to at least seven other dealers I ended up purchasing from Riverside. Jeff and Chase were both exceptional to work with! From providing pictures, FaceTime walk around of the vehicle, handling all the DMV paperwork (I was shocked that several dealers wanted me to do it once delivered), and the logistics of getting the vehicle delivered (extra kudos to the delivery driver for getting it to me at 8pm on a Sunday), they truly made the process so easy I couldn't say no AND the deal itself was still inline or better than the other dealers I was working with! In all my years of buying vehicles and dealing with dreaded dealers, this is the first time I'm genuinely happy with the service that was provided! Honestly I cannot say enough good things about my experience!

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 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!

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 would like to thank Keith Edelman for his professionalism and compassion during a trying and stressful period of time. My wife was hospitalized following a serious accident that totaled our vehicle. During her first week to 10 days after release she required close attention, and we needed a replacement vehicle. Keith had been our contact for three previous vehicles so I called him. I had seen a unit on Lighthouse’s web page and wanted his opinion of it. I then asked him if he would/could set things up so I could drop by at an established time and date, sign necessary papers, complete the deal, and drive it home. Keith, and others on the team, did just that. I do believe it to be above and beyond normal procedure and I truly appreciate Keith’s efforts in this matter. Thank you Keith and Lighthouse GMC!

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.

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 appreciated the quick service! Fair price for my trade in. Knowledgable friendly sales staff. Very professional! Keith Edelman and Jon Tharp did a great job!! Answered all my questions. Well organized! I will definitely by here again!! Thanks so much!!

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

Kieth was great to work with. He explained every part of the transaction and really helped on all the technology that the new Buick has.

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.

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

This truck is the base model and that is exactly what we were looking for. A good solid truck without all the fancy technology. It drives like a dream, handles just as well and the interior is sleek and well designed. Perfect black on black exterior.... a man's truck.

Great very welcoming. Offered beverages and snacks. Got our salesman quickly so not much of a wait.

We have owned our GMC Sierra 1500 for approximately 9 years now. The only real disappointment with the vehicle is that we had to have a full transmission replacement Just after the 100k mile without any warning whatsoever. The truck now has 107k miles on it and now , again out of nowhere, we are experiencing slipping in the trans and the engine light is now flashing. Very disappointing since we are starting to feel uncertain about the reliability of the vehicle now. The truck itself is gorgeous and shows ZERO signs of its age, sporting new rims and tires and a lifted body and no rust on the body at all. We hope there are no major issues with the engine as the vehicle has always been maintained as needed and on time for regular servicing at the dealership.

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.

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.

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.

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

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 bought a 2019 GMC Sierra Elevation. I traded in a FULLY loaded 2015 Sierra SLT, that I was really sad to see go, but the Elevation really sold me on styling and ride quality. I lost a couple high end bells and whistles, but the overall performance and look of the truck make up for it big time!

Came in looking to buy a 2 year old Ram Truck, the salesman and sales manager were very helpful and honest by getting me in a new truck for less than it was going to be to buy a new one

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

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.

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!
