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

My experience with Kunes belvidere
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.

We purchased a used car from Robert and he was extremely respectful and went out of his way to be helpful. We needed to get a car trailer to get the car back to Louisville Kentucky. He was able to find one and reserve it for us. Everyone at the dealership was very nice and helpful. We enjoyed dealing with everyone. We will always remember the great service and friendly staff. We will remember them if we make any future car purchases.

I have to say that Ryan and the staff at Napleton sure know what they are doing. They were quick to answer any questions I had and took away the fear of buying a car! They were friendly and knowledgeable and NOT pushy like most car salesmen. I walked away with a vehicle that I love and a great experience!! Thank you Ryan for all your help!!

Buying my Camaro from Castle Chevrolet in McHenry was an
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.

My sales person at Castle Chevrolet was Tony Twall. He was awesome to work with. He answered all my questions and was very knowledgeable. I have to say that this was the best vehicle buying experience I have ever had. My next purchase will be with the Castle dealership in McHenry IL and I will ask for Tony to be my sales person.
