New and used 2026 GMC Sierra 1500 Elevation trucks for sale near Long Lake, IL

The buying experience with Jarvis was an absolutely wonderful experience from first handshake to driving off the lot. His professionalism and knowledge were apparent from the beginning. He also took the time to get to know me on a personal level through genuine conversations. It was beyond easy to see that Jarvis takes the utmost pride in his work. I am grateful for the entire experience with this gentleman. He is absolutely the best around! Highest recommendation on all fronts!

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

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.

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. They are trustworthy and truly care about the customer. Their work ethic and philosophy reflect heavenly standards. I will never go anywhere else!

Jamie was great. No pressure! Went in to buy one car and ended up buying two cars.

I haven't had time to get together with the dealership I am hoping to go in this weekend.

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.

Aleksei and the rest of the team were great. No pressure environment. The process was efficient. Team was very friendly and courteous. Highly recommend.

I was very impressed from start to finish. Shelley Barr & all her associates were very knowledgeable, kind, helpful, and honest. I appreciated everything they did to make buying a new car enjoyable and not stressful.

Shelley Barr was the very best salesperson I have ever dealt with and I have purchased lots of vehicles!!

Fantastic people and service, it’s what brings me back here. I could go anywhere, but because of the people, I come here.

Have never been disappointed in 30 plus years dealing with service department and their employees. If there turns out to be more problems than what you came in for they video the area and you can see it on your phone. Would never think of going to a different place for service.

The best ever, I recommend everyone to go the to buy from them. Wonderful customer service!

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.

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!
