Turned into a great visit
Thank you so much for a great experience. Chad, the salesman, that I worked with was great. I was a bit nervous before coming in this morning due to my daughter's experience with a salesman at the Kunes next door to this one. But it quickly became a great visit. He was patient and did everything he could so I could drive the car off the lot today. Everyone was very helpful and friendly. He also promised to get me a manual for the Hyundai Tuscon I bought that is missing. I hope he keeps that promise. The salesman, Roel, who was the one next door that my daughter had was not so good. He was demanding and was not very truthful. I believe that he would sell anything or say anything just to make a sale. He demanded that I get in there to cosign for my daughter for a car that was way over her means. Cosigning for someone is a very huge thing and should never be demanded even by a salesman.

Excellent service
Anytime I call and let them know that there’s a problem with my vehicle I bring it in and they take care of it. Found out yesterday that there’s something wrong with my transmission. Thank God for their warranties. I have a special needs son and I need a bigger vehicle and because of them I have that bigger vehicle.

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.

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.

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!

My sales person at Castle Chevrolet was Tony Twall.
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.
