Great Dealership!
This was my family’s second vehicle purchase this year from the Kunes family of dealership’s. Can’t say enough about the customer service and professionalism. Mike Meyers did a great job of finding the truck I was looking for, quickly and at a good price.
This truck has a jerk when changing gears sometimes.

A one-of-a-kind car salesman
I was referred to Anastos by my aunt, more specifically to Mourice. The first night I was there, he found me the perfect car. Exactly what I was looking for. Then, he proceeded to do everything in his power to make my payments affordable, being that I'm a full time student and cannot work as much as I should. I came back a few days later to inquire more about the vehicle to find out that not only did Mourice accomplish exactly what he said he would, he went beyond that. The loan payments... including a 100k mile warranty, came to be 2/3 the price of the exact same car without a warranty from a different dealership a mile away. Aside from Mourice giving car salesmen a great rep, he was an all around great guy. Before we even spoke of the car, he displayed genuine interest in my schooling and plans for life, showed me some of the owner's specialty racing cars, and invited my mom out for pasta and wine. Which I approve of. Needless to say, if you want a car.... You want Mourice.
Great Buy!
This truck is amazing. Turning heads all over as we tour the area. Those riding with is also enjoy the comforts and safety features. Great Buy!

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.

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.

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.

The entire team at this location far exceeded our expectations! Our sales consultant Sandi was extremely easy to work with, and he had our best interest in mind when working on a deal for a new truck. When it came time to financing, Alex ensured we got in and out with exactly what we needed. He provided us personal stories bridging to his recommendations that help guide my wife and I in a direction that surpassed what we originally had in mind. Finally, throughout the visit Edgar and Manny ensured we felt comfortable as we worked though a deal that would ultimately have us driving home without any doubts in a vehicle that can grow with my family. They were the cherry on top to an already excellent experience. Thank you from the bottom of our hearts for such a great team!
