New and used 2026 GMC Sierra 2500 trucks for sale near Lake in the Hills, IL

It was a pleasure working with Sam at Woody Buick GMC in Gurnee. The whole staff is friendly and professional.

I have to say that Ryan and the staff at Napleton sure know what they are doing. They were quick to answer any questions I had and took away the fear of buying a car! They were friendly and knowledgeable and NOT pushy like most car salesmen. I walked away with a vehicle that I love and a great experience!! Thank you Ryan for all your help!!

Made a online appointment came in and they did a oil change and tire rotation. Happy with the service.

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!

Jarvis was the best salesman I’ve ever had and made my experience buying my new truck truly enjoyable. I highly recommend them.

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.

Overall, the service was professional, informative and understandable from beginning to end. I came in explaining what I was looking for and that’s how it was through the process.

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 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.

This is an update to previous review. I bought the cerma plate protection package but was unhappy with the interior. I took it back and it turned out that nobody even worked on the interior. They did it while I waited. If I hadn't taken it back I would have paid for something I didn't get. The service dept. was a little upset with my mood and attitude, but when they found out no-one had even worked on my interior they were very apologetic and nice about it and thanked me for bringing it to they're attention. I don't like dealers and this is a perfect example of why.

The Advisor Tony and mechanic Technician Klaus are the best. I give both of them 10 Stars for such great service. These two both strive to achieve the performance level of Excellence in their jobs everyday. Thank you for such great work

Kevin was very helpful and gave me a deal on the Sierra 1500 that I couldn't refuse 10 out of 10

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!

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