New and used 2025 GMC Sierra 1500 trucks for sale near Johnsburg, IL

Jose is the best i have bought multiple cars from him in the past years. when you get here make sure you ask for him.

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

Kim was incredible in helping me get my repairs covered by my extended warranty! Details of service were provided and car was ready when needed.

Thank you so much for a great experience. Chad, the salesman, that I worked with was great. I was a bit nervous before coming in this morning due to my daughter's experience with a salesman at the Kunes next door to this one. But it quickly became a great visit. He was patient and did everything he could so I could drive the car off the lot today. Everyone was very helpful and friendly. He also promised to get me a manual for the Hyundai Tuscon I bought that is missing. I hope he keeps that promise. The salesman, Roel, who was the one next door that my daughter had was not so good. He was demanding and was not very truthful. I believe that he would sell anything or say anything just to make a sale. He demanded that I get in there to cosign for my daughter for a car that was way over her means. Cosigning for someone is a very huge thing and should never be demanded even by a salesman.

Anytime I call and let them know that there’s a problem with my vehicle I bring it in and they take care of it. Found out yesterday that there’s something wrong with my transmission. Thank God for their warranties. I have a special needs son and I need a bigger vehicle and because of them I have that bigger vehicle.

Excellent, from the day I walked in to finance my truck every member from Sales to Finance were 100% committed to the sale. My process was hassle free

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.

Excellent service from start to finish. They have the best selection of truck campers and they set me up with everything I needed and demonstrated how it all works. Very Nice :)

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.

We purchased a used car from Robert and he was extremely respectful and went out of his way to be helpful. We needed to get a car trailer to get the car back to Louisville Kentucky. He was able to find one and reserve it for us. Everyone at the dealership was very nice and helpful. We enjoyed dealing with everyone. We will always remember the great service and friendly staff. We will remember them if we make any future car purchases.

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.

I arrived late to pick up my vehicle. Fortunately one of the Service writers noticed my arrival as he was leaving for the night. He came back to the dealership and secured my vehicle and billing. Great service.

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.
