Used GMC Sierra 2500 trucks for sale near Northbrook, IL

Chris was helpful and patience while dealing with us and help get what we need for trade in and purchase.

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 were literally about to go with the dealership, but thanks to meeting Kostya, we paused and ended up getting a much better deal. Big thanks to him — really appreciate his help.

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.

Great experience. Alex was a charm to work with for the truck I been wanting.

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!

Buying my Camaro from Castle Chevrolet in McHenry was an outstanding experience from start to finish. I worked with Eric Loredo, who set the tone by doing a full virtual walk around and video of the car before I arrived, answering all my questions in real time. When my wife and I landed at ORD, the car was spotless and ready to go. Finance Manager Mike Lazzara had all documents sent ahead so I could DocuSign, making the delivery quick and smooth. Sales Manager Matt Knudson, GSM Jerry Spanier, and Andrew Sytsma (who wasn’t my salesman but still took time to chat and share product knowledge) all played a part in making this one of the easiest purchases I’ve ever had. The team knew my previous car was totaled in a tornado, and they went above and beyond to make this out-of-state transaction simple and stress-free. Eric and the entire Castle team reminded me that buying a car doesn’t have to be a battle. I would absolutely buy from them again.

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.

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.

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!

Steve was a great salesman and helped me find the car I was looking for with everything I needed! Steve and his team were a big help and I’m looking forward to enjoying my new Tahoe. Thanks Advantage!

I brought my car in for an oil change and multi point inspection. the inspection dealed that I a front brake issue. Mike, the employee I dealt with describe the issue and what it would take to repair it and how long I would have to wait he offered free transportation home if I wanted. because of the distance that I would have to travel there and back to home, I opted to delight the two hours in the lounge. I had coffee and water and I was fine. Mike came in several times to talk about the repair. He also said he had a rebate coupon I could use and he pointed out. I had points in my Buick awards account that I could convert to dollars to pay for the repair. That was very good service save me money and the car is running fine

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!

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!

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.

Frank was friendly and helpful. He look up my records to make sure I was not receiving and paying for unnecessary service. He provided a coupon.

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

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

Great power and yet great economy. Love the safety features with the cameras and side vehicle warning. Camera that shows side of vehicle, including trailer when turn signal is on is great. Also appreciate the bed camera for hooking up gooseneck trailer.

I had a fantastic experience at this dealership! From the moment I contacted the dealership while I was in Tennessee, I flew in, and the staff was incredibly friendly, welcoming, and professional. Uri (The rep) took the time to answer all my questions, made sure I felt comfortable, and went above and beyond to help me find the right car. The entire process was smooth, transparent, and stress-free. It’s refreshing to deal with a team that truly values customer satisfaction. Highly recommend this dealership to anyone looking for great service and an amazing team!

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

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.

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

alex gave me a great deal on our new buick..... thank you so much alex.
