New and used 2026 GMC Acadia for sale near Genoa, IL

Bill was fantastic to work with! Whole process took only a couple of hours and everyone was very helpful. Pricing was transparent and they worked with me to get me best interest rate possible.

Chris does an outstanding job every time I visit. He is very accommodating and always aware of my needs and my time. Only place I service all my vehicles (3) and drive 30 minutes even though there are 2 Chevy dealers much closer.

Marquartd of Barrington is an amazing dealership because of their integrity and great customer service! I bought my new car 2017 and have relied only on them to maintain it. They are trustworthy and truly care about the customer. Their work ethic and philosophy reflect heavenly standards. I will never go anywhere else!

Excellent as well as timely service. However, was not told in advance that paying with Credit Card would have a 3% fee.

Super honest deal. Used car as advertised, no surprises, no pressure. They detailed it for us while we did the paperwork.

Easy to schedule service. They shuttled me to my home and back and were super fast and on time!

Thank you to the service team for your getting me all set for my roadtrip!

Great service and people fast and easy buying process will recommend to other family and friends fun environment and provide coffee and water will be back for all my service needs and repairs

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.

Great people. Great service. Highly recommend Erick and team. They will give you a solid deal

I have brought my vehicle in for every oil change I have needed. Always courteous and professional, my car gets a diagnostic check every time and is freshly washed. I like that the Service Department send out coupons, and making an appointment is easy online or with a phone call.

Most pleasant waiting room anywhere and the friendliest service people.The mechanics always attempt to fix problems before they start. Also wait time ia always fair.

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

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.

As always, service and service reps were great-wonderful dealership and service department?have purchased cars from dealer for many, many years and will continue to do so.

Very smooth experience. Seann is an excellent young salesman. Darien will do anything to work with you. Erick, the manager is very accommodating. A++++ dealership.

Frank was friendly and helpful. He look up my records to make sure I was not receiving and paying for unnecessary service. He provided a coupon.

Brian at Marquardt service department was extremely helpful to get my car all ready for winter with a new set of tires. I appreciate having a great dealership near by to handle my car needs.
