New and used 2026 GMC Yukon for sale near Union, IL

If you're looking to purchase a new or used vehicle, I highly recommend Arlington Heights Buick GMC. This was my first time purchasing a vehicle from a dealership and they were great. From the managers and salesman, all the way to the financing department and cashier, everyone was super nice and helpful. Keep up the good work. I will definitely be back in the future! Thanks again A.H. Buick GMC!

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.

Great customer service, was wonderful working with Jessica and Moe. I will be back again.

Lamia was Amazing!! She was so friendly, personable and I walked out with the car I wanted!!!

Great people to help in getting the car I wanted. The service to make things happen that insured trust and honesty was greatly appreciated. Thank You.

Nice updated, clean dealership. Staff is super helpful, not pushy & very knowledgeable. A lot of familiar faces from the last time I was here.

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.

Jim Sprandel sevice mgr. very nice man and also explains everything to you clearly.The rest of the staff was also very pleasant. I would give this dealership 10 stars if I could. My car was washed for me and I needed it considering it was a cold winter day.

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

Salesperson did a great job answering any of my questions and getting back to me!

The Marquardt experience was fantastic. Our sales rep, Fiona, was very knowledgeable and provided world class service. If you are considering a vehicle from this dealership, we highly recommend her.

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

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.

Great staff and very good deals on new vehicles. Quick, friendly and very helpful. I would recommend if your looking for a great deal check with these guys first. They will get you that Great deal others can't.

The Advisor Tony and mechanic Technician Klaus are the best. I give both of them 10 Stars for such great service. These two both strive to achieve the performance level of Excellence in their jobs everyday. Thank you for such great work
