New and used 2025 GMC Sierra 2500 trucks for sale near Kildeer, IL

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

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.

I have bought high quality two used cars from this dealership and gotten service there as well. The care and time that the entire staff gives to their customers is beyond exceptional. They are always fair and always go above and beyond. (Insider tip: Ask for Mr. James!)

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.

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.

Could not have asked for a better experience. The salesman was very helpful and waked us thru everything in a way we could understand. it was a wonderful experience and would recommend this dealership to anyone looking for a new car.

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 have visited more than 10 dealerships for my next lease but they are all not supportive. Here at Arlington Heights Buick, I met Shelley Barr and made a deal !! She is well informed and tried helping me a lot. Just try to go and meet her then you will realize it.

Humberto was great! Good customer service, would definitely recommend the dealership for your next purchase!

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.

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.

Great service! Mark was awesome. My appointment ended earlier than expected too. Plus a comfortable waiting area with coffee!

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.

We had a great experience at Woody Buick GMC. My experience with Mike was Jarvis was great. They explained all that I need to know. We bought a GMC Acadia.

Excellent customer service! Manny and the team were very informative. Thank you Woody Buick GMC!
