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 wife and I recently purchased a new car for her at Kunes of Belvidere. I am in sales and I have purchased many cars over the years. I’m not easily impressed but, I have to say, “Mo” Owaynat the general sales manager and numbers guy went over and above to get a deal done for me and my wife. On top of being a really nice guy, he worked hard to get a deal done that fit our needs and I felt the whole time like he was working as much for me as he was working for the dealership. He is a good human being. Go talk to him and you’ll see what I mean. And our experience with our sales person, Robert “Brinck” Brinckerhoff was fantastic. Being in sales, I very much appreciated his congeniality, low pressure approach, and his customer centric interaction. I felt like I made a friend. If you’re in the market for a car, go see “Brinck

This is an update to previous review. I bought the cerma plate protection package but was unhappy with the interior. I took it back and it turned out that nobody even worked on the interior. They did it while I waited. If I hadn't taken it back I would have paid for something I didn't get. The service dept. was a little upset with my mood and attitude, but when they found out no-one had even worked on my interior they were very apologetic and nice about it and thanked me for bringing it to they're attention. I don't like dealers and this is a perfect example of why.

Great customer service, was wonderful working with Jessica and Moe. I will be back again.

Lamia was Amazing!! She was so friendly, personable and I walked out with the car I wanted!!!

Great people to help in getting the car I wanted. The service to make things happen that insured trust and honesty was greatly appreciated. Thank You.

Great people. Great service. Highly recommend Erick and team. They will give you a solid deal

Very smooth experience. Seann is an excellent young salesman. Darien will do anything to work with you. Erick, the manager is very accommodating. A++++ dealership.

We had an incredibly smooth and pleasant experience at this dealership from beginning to end. The entire process was seamless from start to finish. Every staff member we interacted with was helpful, courteous and professional. Buying a vehicle from Seann Omara was particularly wonderful— he is knowledgeable, helpful, and genuinely committed to making sure we got the best deal possible. We left very pleased and would happily recommend Napleton Buick GMC to others!

Most pleasant waiting room anywhere and the friendliest service people.The mechanics always attempt to fix problems before they start. Also wait time ia always fair.

As always, service and service reps were great-wonderful dealership and service department?have purchased cars from dealer for many, many years and will continue to do so.

Brian at Marquardt service department was extremely helpful to get my car all ready for winter with a new set of tires. I appreciate having a great dealership near by to handle my car needs.
