Used GMC cars for sale near Rock Island, IL

We had a very pleasant buying experience.

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. :)

Quality of used vehicle was what was advertised. Salesman were friendly but one was a little pushy to close the deal. My payment is higher than I originally wanted. All in all I would buy there again.

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!

Was very good and Justin was very friendly and knowledgeable exceptional in helping me find exactly what I was looking for very happy.

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.

Worked with JT and Max for the purchase of a 2020 GMC Acadia. We went in with a set monthly payment idea and they worked with us until we got to where we wanted to be. 10/10 customer service experience! Even if things wouldn’t have worked in our favor, we would have left knowing they did everything they could and actually care for their customers! Highly recommend!

Excellent and reliable, only thing buyers have to do is buy a AFM disabler that you can stick into OBD2 port to avoid lifter failure (longer story, nobody wants a V8 to run in V4)

Best people great inventory more than flexible finance got me a great deal exactly how I needed it. Would recommend to all friends and family

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.

The sales team and management are amazing.!! Bought a brand new car from Calieb and he made this a great experience! All I had to do is come in and sign papers and I was out the door.. Thank you Calieb!

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.

Love my 2012 Escape and My Mustang I purchased from people I trust to Maintain and Service them.

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 good customer service! This is the second vehicle that we have bought from them, and so far so good!

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 !

Bought a used BMW Z4 from an online ad from this dealership and had them deliver it to me. The car arrived and is just as advertised. The entire process was easy and I felt like everyone was honest and upfront about everything. I got an awesome car at a price that was appropriate. I would not hesitate to buy from them again.

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!

Great people, great service and great waiting room where I can drink my complimentary coffee.

Does anybody else’s truck just sit there after you put it drive? I have to bump the accelerator to have it go into gear. ??????????????????????????????????????????? ?????????????

We had an excellent experience, we will definitely go to Clinton when purchasing our next 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

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 have purchased all my vehicles from here and they are phenomenal!! Great customer service, attentive but not overbearing, very knowledgeable about the vehicles they have on the lot and what features they have. Staff that we interacted with were patient and understanding and great with my kids who have special needs, That really means the world to my family! When getting service done on my previous vehicle it was fast and convenient, even when we were waiting for parts they kept us updated with where they were in the process. They really go above and beyond to make sure we are happy and just make us feel welcomed when we stop in. Very happy with my new Electric Blazer!

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.

Very Satisfied, great group of employees. My experience is appreciated. Look forward to the relationship with this location during to my recent purchase of a brand new vehicle.

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

This was the least stressful purchase at a dealership that I've ever had! No surprises.

Perfect . If you want to get good emotions then you need this GMC Yukon Denali XL . L M k if you have any questions please

Salesman great but no financing . I would have bought the rogue! Thank you for all your help.

I always bought the GMC Acadia (4 times) but decided to try the terrain. I absolutely love it and it's a great car for zipping around in town. I would take it for a weekend trip but not on a long trip as it doesn't have a lot of cab room, but for two people it is fine

I have been a return customer to Zimmerman for over 15 years! Matt Rizzo is an amazing sales person and is so easy to work with! He makes the purchasing and leasing process simple and non-stressful!

Absolutely LOVE this car is one of my favorites by far. Midsize SUV with all the features of a full size luxury vehicle. Can’t beat the heated seats, power lift gate, and the amazing panoramic sunroof they added on these models. Will continue to buy this model for years to come highly recommend an affordable and practical vehicle!

After several years of helping me keep my 2013 Tahoe rolling smoothly down the highway; Jay, Randy and the Key Auto Mall Team helped me select my next ride -- a 2023 Yukon XLT AT4. Customer service is first and foremost with this team. I recommend all my friends and family to give them a call. I appreciate their hard work and will continue to bring my vehicle for service because that department rocks too!

So far I have been enjoying my 2025 GMC Canyon Denali. It has a great ride and is very comfortable. The Canyon drives very nicely and has plenty of power for my usage (I don't tow anything). It tracks well and has a very smooth ride that rivals previous BMWs (328 and X5's). I have had zero issues but the vehicle is only 1.5 months old (approx 1,700 miles on it). THe only downside (which many people agree on) is that it is seriously lacking storage space. Center console storage is about 1/2 what it was in my 2020 Jeep Wrangler and under seat storage (rear seats) is almost useless ..very little space. That being said, I'd still recommend the GMC Canyon and hope it continues to impress me.

Greene’s sales representatives were extrmely helpful in guiding me toward the used car that my specifications called for. This is unlike what I have experienced elsewhere. I’d recommend Greene!

2019 Canyon Denali. All sorts of bells and whistles, several that I don't really need. Biggest complaint: no memory seats and no Homelink garage opener. Ridiculous. What accountant made that decision?

Could not ask for an easier, less stressful experience for buying a vehicle. Carter Marten was our salesman and he was one of the best I have worked with. He let us take our time looking at our new vehicle and we did not feel rushed even when it was close to their closing time. We will be back for our next vehicle purchase!

I brought this truck in 2019. I kept taking it back to the dealership to get tweaked several times. Once it was figured out, never got any problems ever again. A little weak on the power side, but, other than that, its a magnificent vehicle. A total work horse. Great on gas. It is totally worth it.
