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

Excellent customer service and great to work with! They even delivered my vehicle to me. Nick in sales is the best from start to finish!

So far so good! This truck is the nicest truck I have ever driven. The stance, ride comfort and options are top notch. I went from a 2023 High Country that was having drive train issues but had all the creature comforts that you would expect in a top of the line truck. With the lack of confidence in that particular models 10 speed transmission issues, it became necessary to reestablish my confidence in my General Motors product.

Team was Great James and Financing department went above and beyond for us

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.

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

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.

They picked up my car from home and had it back to me so quickly!!!

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.

Manny make mine car buying experience, very simple and efficient I will definitely come back to him again when I need another Buick.

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.

This was my 6th Buick Envista purchase with Manny from Woody is very knowledgeable and professional.

Have trusted this dealership for over 25 years. I wouldn’t think of bringing my 2 Buicks anywhere else. They only do necessary repairs which I appreciate and will give you a timeline as to what to expect down the road when it comes to doing work. They value you as a customer and do everything they can to help you in all aspects serving you.

I have never been happier since I bought my Buick at The dealership in Barrington Illinois Tim McIntyre was our salesman and Dave the manager Patrick in the finance department Went far above any expectation I had for any dealership we had been looking for a car for several months I’ve never bought a Buick It truly is The best car I have ever owned This dealership Made this purchase so enjoyable I recommend them to oeveryone

Brought my my car in for normal service and Mark Took care of me. He was great. He pulled up my history on my car and made recommendations for what I needed and explained everything they would do. Also gave me approximate cost of service which was Very close to his quote. Work was done very quickly. Just a great experience. I will be back for my next service when needed. Also everybody that works there were very friendly .

Andrew Allen was amazing partner in my purchase so patient and great knowledge related to my Encore and Buick. The walk through was very thorough even providing me with his direct access for all future questions.

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!
