New and used 2025 GMC Sierra 2500 trucks for sale near East Dundee, IL

Matt, Azbel were top with great first impression, and even better lasting impression! Great Service also from Moshe, Jeremy, Tino, Tamu, and welcoming crew. I am happy with my beautiful and spotless new car and dealership is the same. Friendly and very knowledgeable crew! I send everyone there for a great car, caring and trustworthy staff who will help you select the vehicle that's right for you!

I worked with Sabrina S. She made the entire process seamless and comfortable. I never felt pressured or haggled at any point. Thank you to Woody, and thank you, Sabrina.

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.

It was a pleasure working with Sam at Woody Buick GMC in Gurnee. The whole staff is friendly and professional.

Have trusted this dealership for over 25 years. I wouldn’t think of bringing my 2 Buicks anywhere else. They only do necessary repairs which I appreciate and will give you a timeline as to what to expect down the road when it comes to doing work. They value you as a customer and do everything they can to help you in all aspects serving you.

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

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

Brought my my car in for normal service and Mark Took care of me. He was great. He pulled up my history on my car and made recommendations for what I needed and explained everything they would do. Also gave me approximate cost of service which was Very close to his quote. Work was done very quickly. Just a great experience. I will be back for my next service when needed. Also everybody that works there were very friendly .

I have brought my vehicle in for every oil change I have needed. Always courteous and professional, my car gets a diagnostic check every time and is freshly washed. I like that the Service Department send out coupons, and making an appointment is easy online or with a phone call.

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