2023 Terrain
Had an AWESOME sales experience when we purchased our 2023 Terrain. Stephan took great care of us and was very knowledgeable. Robert & Ryan in the finance department were easy to deal with and very responsive to what we were looking for. Did not feel pressured at all. Overall a great interaction with Kunes Lake Geneva.

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 arrived late to pick up my vehicle. Fortunately one of the Service writers noticed my arrival as he was leaving for the night. He came back to the dealership and secured my vehicle and billing. Great service.

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!!

I had the BEST car shopping experience here.
I had the BEST car shopping experience here. I never felt pressured to know exactly what I want or to buy a new top of the line right then and there. Steve was a gem and listened to what I wanted and kept my budget in mind. He was realistic with expectations and never pressured me into anything. With other dealerships, I felt trapped like I couldn't leave until I bought something from them. Not here. Steve understood that buying a car was a huge commitment and let me have my time to think about what I wanted and what was available in my budget. I was able to leave the dealership to think about my options and wasn't hounded with calls and messages asking me when I was going to buy or what the dealership could do to make me a customer. I had space to think and make a decision that didn't feel forced. Even when I bought my new car, everything was explained in detail and they made sure to give me time to ask questions so I knew EXACTLY what I was getting into. As a first time car buyer, this was a dream of an experience. I had been to 3 other dealerships and Lou Bachrodt is second to none. If you live in the Rockford area, this is the place to shop for a car and make sure to ask for Steve!

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

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.
