Used GMC Sierra 2500 trucks for sale near Flanagan, IL

Jarrod made the car buying easy and painless. Got the cars we wanted try. Great buying experience.

I love my 2021 GMC Denali 2500HD. I have gotten more complements on this truck than any other vehicle that I have owned. I get great highway fuel milage average 19-26mpg,which is great for a heavy duty truck!

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

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.

Great experience. I always feel very well informed and appreciate the Barker Team.

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.

We found our vehicle on line and messaged about it. We were told it was sold, However, the next day we got a call from Hunter stating that it was in fact, not sold and to come as soon as we could. He had the vehicle warmed up for us and ready to take on a test drive. Cory Who is the sales manager was also wonderful to work with. Holly and their finance department is an amazing person. I would recommend anybody who needs a car to go to Heller. When you buy from them, it’s like you’re buying from family.

This truck is the truck that all others should look up to. It rides great, will tow a house, runs smooth, and gets great fuel economy. The Allison transmission is so smooth. The AT4 looks great too.

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

Great people. Todd so professional & nice to speak with. They like to work with customers and make it happen.

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.

Mr Heller and his sales staff and financial staff are top notch. My salesman was Ian. Fast and easy no xx and no pushy attitude. Knowledgeable in their inventory and allowed me to take my time. I signed all documentation online and they delivered the truck to me. Outstanding service.

I work with Chris the sales manager and he was real professional sold me a Cadillac Escalade the truck was in great condition treating me like family

We recently purchased a used Jeep Wagoneer from Heller Ford in El Paso, IL, and the entire experience was nothing short of fantastic. Huge shoutout to our salesperson Onie Maisonneuve, who went above and beyond from start to finish. We live about an hour and a half away, but Onie made the process incredibly easy by handling everything over the phone ahead of time. By the time we arrived, all that was left was a quick test drive and a bit of paperwork—start to finish, we were in and out of the dealership in around 30 minutes! A couple of days after taking the vehicle home, a mechanical issue popped up. Onie was immediately responsive and had a loaner vehicle arranged and delivered to us the very next day. The service department didn’t miss a beat either—they had the necessary repairs completed quickly and efficiently, making sure we had our Wagoneer back just in time for a planned family vacation. I can’t recommend Heller Ford highly enough. If you’re looking for a dealership that truly stands behind their vehicles and values customer service, look no further. Ask for Onie—he’s the real deal!

So far so good! This truck is the nicest truck I have ever driven. The stance, ride comfort and options are top notch. I went from a 2023 High Country that was having drive train issues but had all the creature comforts that you would expect in a top of the line truck. With the lack of confidence in that particular models 10 speed transmission issues, it became necessary to reestablish my confidence in my General Motors product.

Love my GMC. Owned a Chevy and this absolutely beats it hands down. Never had any issues. Inside is very comfortable and can't imagine driving anything else

I did not end up purchasing a car with this dealership however I did not because of the honesty of the dealership. The dealer fully disclosed prior damage the vehicle had and the repairs. It was my decision to not purchase because of the damage.

We have purchased four vehicles from the Sam Leman group. We have purchased two vehicles recently from Isaac. Isaac is super responsive, punctual, honest and hard-working. He is a pleasure to work with especially under the pressure of purchasing a car. Overall, the experience is wonderful, the dealership itself could use an upgrade.

Wonderful truck. Has had zero problems. I am trading for a new one. Truck is all original with no modifications. Truck is in excellent condition.

this truck fits my needs better than the other 2500 models. Its hauling and towing performance along with its many people comforts will satisfy us for a long time to come.

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.

Love everything about this Duramax Denali except the fuel mileage. 13-14 Mpg tops when not towing. Bought truck cause previous was stolen. Wish I still had my 6.2 High Country!
