Used GMC Sierra 2500 trucks for sale near Deer Park, IL

It was amazing. Efficient, pleasant, and quick. We love our new Buick. We usually do not look forward to the process of purchasing a car. It was actually enjoyable.

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.

Eduardo gave me an amazing service at the dealership and helped me find a car.

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.

Fast, efficient, friendly, wonderful, second time buying from this dealership. I highly recommend Denise, she is wonderful and Dennis in finance was great whole thing took 2.5 hours and we were off the lot smiling.

Jordan was amazing. He made sure we felt comfortable and provided us with all our options. He even spent time with us after the purchase to ensure we knew all about our vehicles features. 10/10 would recommend!

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.

Ted was great it was a great experience this is my fifth car I bought from this place

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!

My first experience at this dealership will definitely bring me back. We are so happy with our purchased! We had Alex Alverio from Sales, he was very professional & helpful, has awesome customer service & we highly recommend Alex. Thank you so much and keep it up!

An advisor of mine recommended Countryside Nissan as a reliable, trustworthy place to buy a car, and this was reflective of my own experience purchasing a car there. Chuck Ippolito is the salesperson I worked with and he was personable, professional and friendly. He consistently worked to make sure we had all the information we needed. Everyone we met at Countryside Nissan was kind, and helped make the experience of purchasing a car less stressful.

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!

Matt in sales is extremely professional. His knowledge of the vehicle was obvious. He throughly explained the car's features with me. I'm glad he was my sales representative with the Castle Subaru dealership.

What a gorgeous truck, runs good, sounds good and has all of the amenities I need although I am looking forward to their next interior upgrade.

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 really appreciate the straight-forward buying process I found at Napleton Schaumburg GMC. Thank you to Yiannis for answering all my questions! Best- Mark

Thank you to the service team for your getting me all set for my roadtrip!

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.

Jon David is an asset to your company he’s a gentleman and a scholar. He put a deal that I won’t forget, and I won’t forget him. My son was very happy and he treated him with courtesy.

Although I didn't buy a high end exotic, I was treated like I was buying one. The 2007 XKR was wonderful and Jackson went above and beyond to answer all my questions, inquiries and upfront about everything with respect to the car. It was prepared beautifully and the transaction was as smooth as could be for an out of state buyer. I would recommend them to anyone looking for a specialty vehicle and hope to deal with them again in the future.

Happy that I purchased at this dealership rather than others in town. Turned out to be better deal and better car!

This is the first diesel I have owned. The power is amazing and I really like the room inside the cab. This truck is a beast... Love it!

I bought a 2011 VW Routan from Auto Gallery. Steve went above and beyond to make my car buying experience painless and easy. Great guys to work with. Will recommend to friends and family.

Worked with John B for a new Bentley. He was quick and efficient, answered all my questions and the car is in mint condition. Car was fully serviced and I love it

Great Cars and also good service. Vincent Vega was very helpful thank you Vincent for all your help. This is our third car from Castle Buick GMC. We loved thank you .!

Awesome service from Huntley ford and it's salesman Rob specifically. Huge selection makes car shopping in one place easy and convenient!

Thanks to Woody Buick GMC for another great experience in purchasing a new SUV. We’ve had the pleasure of leasing and purchasing 8 vehicles through Brian Newcomb over the years and he never disappoints! He always finds us just what we are looking for and makes sure we walk away as happy customers. If you are looking for a new vehicle, Woody Buick GMC is it!

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.

We really appreciated how dedicated the staff at Huntley Ford were. We spoke on the phone and visited to check out a few vehicles with Daniel. He was very patient and wonderful to work with. Although we didn't purchase a car during our visit, we would recommend that anyone visits the dealer for a great experience.
