New and used 2026 GMC Acadia SUVs for sale near Union, IL

My service advisor, Michael, did a great job of communicating the progress of my service appointment. Not all the necessary parts were in stock after the diagnosis, but he kept me apprised of the status of their arrival and made sure I had a loaner when they came in. The technicians did a great job and returned my vehicle in great condition.

Great vehicle. Has great features and it is a very smooth ride. It is quiet on the road. Great gas mileage (over 28 mpg combination town and road).

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.

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.

The best ever, I recommend everyone to go the to buy from them. Wonderful customer service!

Service team thorough and helpful. Efficient check in and updates provided throughout the service. Nice to be able to select the service person when setting the appointment.

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

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.

Aleksei and the rest of the team were great. No pressure environment. The process was efficient. Team was very friendly and courteous. Highly recommend.

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.

I was very impressed from start to finish. Shelley Barr & all her associates were very knowledgeable, kind, helpful, and honest. I appreciated everything they did to make buying a new car enjoyable and not stressful.

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!

Shelley Barr was the very best salesperson I have ever dealt with and I have purchased lots of vehicles!!

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.

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.

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 really appreciate the straight-forward buying process I found at Napleton Schaumburg GMC. Thank you to Yiannis for answering all my questions! Best- Mark
