I made an appointment for an oil change & my car was making a sound when braking. Carlos went above and beyond to have my car inspected & find out exactly what the problem was. I have never been disappointed. I know I?m in good hands with Carlos!

Napleton Buick Service Department
Kept me informed of status of repair so I could decide if I wanted to wait for the repair. Customer waiting area always clean and comfortable. If the repair extends longer than I can wait, will provide.a ride home which is a great service. Always explains what is needed and what can wait until next service date so I can be prepared for future maintenance. This helps me keep my car in great shape and prevents major issues.

It is a service business.
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
