New and used 2026 GMC Sierra EV trucks for sale near St. Charles, IL

Anthony greeted me in the parking lot and was friendly and professional. He quickly brought the car out that I wanted to see. Negotiations were very fair and the paperwork was done in a timely maner. I love my new/pre-owned HyundaiTucson. Thank you Anthony and the team! I'll see you again when I need my next vehicle.

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.

I live far from this dealership but they had exactly what I was looking for. The whole experience was very favorable . Everyone I has contact with was very professional and courteous. The salesman I worked with Joe Kendall was excellent. The day after the purchase I noticed that a light strip was missing on one of the outside mirrors. The service dept fixed it. In my opinion they are a top notch GM dealership . Keep up the good work😀

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

From originally purchasing my car at Haggerty to having my car serviced at Haggerty, my experiences have all been positive. Everyone is friendly and answers all of my questions. Work is done well and on time.

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.

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.

Very professional, excellent communication Friendly staff, and had the vehicle we wanted, would deal with them again

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!

Todd was very helpful and made sure my car was pulled inside when leaving as it was very slippery outside

Service rep was ?on the ball? Understood my request and my lack of correct nomenclature

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.
