New and used 2026 GMC Sierra 1500 Elevation trucks for sale near Trout Valley, IL

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.

Easy purchase experience, would recommend to anyone looking for a new car. Everyone there was friendly and made the whole process as smooth as possible

Chris Lahey was an exceptional person to deal with and got us the car of our dreams!

A little expensive, but comfortable, quiet, smooth ride. Great performance out of the 6.2L and better than expected fuel economy in the low 20s. Outstanding interior and good looking exterior, especially in the Downpour Metallic color. I don’t have 700 miles on it yet and have owned it for 3 weeks. Therefore, I can’t pass judgement yet on the reliability, but so far I am very satisfied. This replaced an 8 year old Ford F150 that served me quite well with only a couple of issues in the 100,000 plus miles.

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.

It was such a good truck honstly the greatest thing I have ever drove in my entire life I am so happy that I have been blessed with this being my first ever car

Super honest deal. Used car as advertised, no surprises, no pressure. They detailed it for us while we did the paperwork.

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.

I have worked with Dan Salisbury for years in regard to leasing various cars. Dan works very hard to find what I am looking for within the payment range I need. Dan never makes me feel bad for additional requests or continued questions. If there are any problems they are quickly resolved. During this last lease I had pleasure of also working with Alfonso Gomez. He was very quick at resolving small issue that I had immediately. Jason Garon in the service department is always amazing about getting my car for any oil changes or needed work. I am happy to recommend this team to others.

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.

This was my first time buying a car at a dealership and I feel really grateful that Jamie was my salesman the day I went to purchase my car. He matched my energy and determination to get the car that I had my eye on. Not once did I feel pressured about anything and he made me feel so comfortable to ask any questions about the whole process. It was a very quick process running numbers and everything and I really do thank Jamie for that because he got straight to the point and I loved his transparency. 10/10 would absolutely recommend working with him.

I brought my car in for an oil change and multi point inspection. the inspection dealed that I a front brake issue. Mike, the employee I dealt with describe the issue and what it would take to repair it and how long I would have to wait he offered free transportation home if I wanted. because of the distance that I would have to travel there and back to home, I opted to delight the two hours in the lounge. I had coffee and water and I was fine. Mike came in several times to talk about the repair. He also said he had a rebate coupon I could use and he pointed out. I had points in my Buick awards account that I could convert to dollars to pay for the repair. That was very good service save me money and the car is running fine

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.

When looking for a new vehicle contact Rocky! He is the man for all your car needs. He’s very good at his job and he makes sure you leave the dealership satisfied with your purchase and with a great deal. Wether you’re in the market for a new or used vehicle he will help find exactly what you’re shopping for. Recommend 10/10

Elliott was incredibly helpful. He had patience and don’t oversell. This allowed us to find the truck that we wanted vs feeling like we were pushed to make a decision. Would buy from Elliott again.

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.

Alex is the man to see he knows his vehicles. Easy to talk to great customer service, he finds the vehicle you need. Alex help us in every aspect. Would highly recommend this dealership and recommend you all to see Alex.

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.

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!
