Used GMC trucks for sale near Cullom, IL

Great service. I love my ford escape. Will definitely do business there again. Shout out to Jeremy for all the help.

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.

A bit short handed on the last day of the year so took a little longer than anticipated. But buying experience was enjoyable. Great people, great dealership.

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.

Alan W. was great to work with. Jason the manager was also extremely fair and worked with me. I live 2 hours away and bought from them because they lived up to their good reviews. Quick response and friendly service.

Our AT4X has been an excellent mid-size truck. The ride is shockingly smooth and the engine has a lot of torque. Wish the interior had less plastic and GM's failure to have a rear view camera mirror or controls for garage/gate contols is inexcusible. Overall, could not be more pleased with this truck.

Heller was great! Bob was very friendly and helpful. Low stress environment and made everything very easy.

One very awesome vehicle. Checks all the boxes you need in a truck and exceeds expectations on quality, performance, and looks great ,too. Love my nre truck.

Excellent overall knowledge and customer satisfaction

I've owned every other American truck and this is my first GMC. I bought the 2500 HD Texas Edition. I absolutely love this truck. It's everything I could have hoped for and more. It is able to pull my 30' travel trailer with no problems. So now when we go out with our trailer I'll have no worries. The look and feel of the truck is outstanding. The 6.6L gas engine actually gets great gas mileage. It gets about the same as my Ford f150 ecoboost. Probably better on the highway. Looking at about 13 miles in the city and 15 plus on the highway. Definitely got a better truck for the price compared to any other american models with the same characteristic and options.

I had a good experience with this dealership.Friendly atmosphere,no rush service,not pushing you to buy!good prices,great cars. If I’m looking for a next car I definitely will check this price first:)

I have loved and owned Chevy and GMC midsized trucks since 98 when I purchased a used S-10. My latest purchase is a 2021 GMC Canyon Denali bought brand new. It's been a great truck until my power steering unit went out due to corrosion. It only has 32,200 miles on it and I have never gotten it wet other than car washes and driving in the rain which is normal conditions. I had purchased a mid grade extended warranty through GMC after my lease was up and purchased the truck. I am being told this is NOT covered due to it being external wiring. So I feel this is a manufacturing malfunction and bad engineering for water to be able to get in to cause such corrosion so beware. This is an open case filed with GM currently to hopefully rectify the matter.

First time dealing with Heller Motors and everything went well. I would recommend visiting this dealership in Pontiac, Illinois.

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

Country Chevrolet is amazing! Steve and his service department have always gone above and beyond 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.

Everything was done as I had asked. Always great service!

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.

Hello, how are you all doing today? I would like to say that it was a pleasure calling this Heller Motors dealership today, 10/17/2025, specifically because of Mr. Don, who didn’t hide any information from me and was 100% honest with me the entire time. It is an honor to work with such a kind and honest Heller Motors dealership, and I would like to give my thanks to Mr. Don for helping me out a ton. I did not purchase the truck yet, but I will, but I have to say this about this dealership and Mr. Don

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

I was shock on how fast my tire came in an was done. Plus they checked on the mice been having problems with them.

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?

Always professional and friendly. Good hometown service with hometown guys. They are always there to help.i would highly recommend this dealership to any of my friend and family and to strangers.

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

I have had my 2011 GMC Sierra for a few years now, i love it. i have hauled multiple loads of wood with the truck loaded too the max and a small trailer loaded to the max. can definitely feel the weight but my truck never hesitates at all. Very impressed with the performance of these trucks. i have worked at a ford dealership for years, but ill always drive a GMC.

I just had my 02 Blazer in for a grease oil and filter and new tires and Corey the technician found problems with the steering components and the radiator leaking and brought them to the service manager John's attention and John gave me several options on repair excellent Service as always I highly recommend this crew always done very well by me

2021 GMC sierra 1500, 5.3, crew cab 4x4, 21000 miles. brakepad monitor lites up. dealership says needs brakes and rotors in back. one mo. on warranty. our rural roads dirty up the monitor. Needs new monitor. brakes look great to me. No noises. dealer says parts on order GM strike. Can't replace myself cause of computer...

I?ve bought vehicles from other dealerships with poor experiences. So I stop buying vehicles from dealers and work on my own for about 20 years. Driscoll motors repaired my truck exactly the way I would?ve done it myself. I value that !!

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.

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.

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!

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.

I paid over $106,000 for this truck with warranty. Do not care much about miles per gal. at that that price range. Just too much truck for me at my age.
