New and used 2025 GMC HUMMER EV SUV for sale near St. Charles, IL

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 initially called this dealer when I saw an online used vehicle for sale. The sales person that answered the call and helped me was Sam. From the initial conversation up to making the purchase of the car Sam helped me in every step. Very knowledgeable and helpful person. I would trust this guy for any other purchase here for sure.

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.

Purchased a Camaro from 900 miles away. Anthony and Dan did a good job and made the purchase easy. They also assisted in shipping the car to me.

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😀

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

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

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

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.

The Advisor Tony and mechanic Technician Klaus are the best. I give both of them 10 Stars for such great service. These two both strive to achieve the performance level of Excellence in their jobs everyday. Thank you for such great work
