Used GMC Sierra 2500 trucks for sale near Saint Charles, IL

Agnes was very helpful through out the buying process and went above and beyond to make sure that I was taken care of during the whole purchase process. I can’t say enough that she is the best in the business and will not lead you on or waste your time.

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.

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.

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!

I highly recommend Golf Mill Ford. It was my first time purchase here and it was by far the best. All the salesmen were very friendly! Ruben went above and beyond to make the purchase and experience very pleasant and I really appreciate that. Great dealership!!

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!

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.

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.

The staff is very experience and professional. The estimate for repairs were in line with the services. I compliment the facilities with free coffee, water and soft drinks.

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

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

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 salesman Esad was great. He was very knowledgeable. Everyone was very friendly and helpful.

Very comfortable buying experience! I had never purchased a vehicle completely by myself belore, so I was quite nervous going into the process. D'Arcy Mitsubishi and Jesus Rodriguez helped me through everything, showed me my options, let me test drive three vehicles, answered all my crazy questions, and made the purchasing process simple. Thanks to them, I absolutley LOVE my new Mitsubishi!

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!

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.

One of the best dealerships out there with some great quality cars along with best customer service. Loved it

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.

But a very nice Nissan Sentra from them I was looking around and found out that they have very good prices and the quality is good too so thank you Andrei for helping me out!

I've owned my truck for nine years now it is never once let me down. I'm about to put my first set a tires on it and brakes other than that I don't plan on getting rid of it it's never let me down and after reading all the other reviews it makes me realize they don't make them like they used to as they used too!

Felt welcome as I entered the door. Staff was available and when I asked for the sales person that I had been communicating with, salesperson was waiting.

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.

Could never buy another truck after owning this. I'm only getting rid of it cause I ordered a 2021. Hands down, this is the best of the best!!

Great Prices, staff and selection of vehicles to choose from! Thanks Jose for an amazing experience

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.

John Giuffre made the buying process stress free. I would recommend going here for your next car buying experience.

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 .!
