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

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.

Easy to schedule service. They shuttled me to my home and back and were super fast and on time!

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!

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!!

I have visited more than 10 dealerships for my next lease but they are all not supportive. Here at Arlington Heights Buick, I met Shelley Barr and made a deal !! She is well informed and tried helping me a lot. Just try to go and meet her then you will realize it.

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

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.

I really appreciate the straight-forward buying process I found at Napleton Schaumburg GMC. Thank you to Yiannis for answering all my questions! Best- Mark

Great customer service, was wonderful working with Jessica and Moe. I will be back again.

From originally purchasing my car at Haggerty to having my car serviced at Haggerty, my experiences have all been positive. Everyone is friendly and answers all of my questions. Work is done well and on time.

Thank you to the service team for your getting me all set for my roadtrip!

I have brought my vehicle in for every oil change I have needed. Always courteous and professional, my car gets a diagnostic check every time and is freshly washed. I like that the Service Department send out coupons, and making an appointment is easy online or with a phone call.

Very professional, excellent communication Friendly staff, and had the vehicle we wanted, would deal with them again

My salesman Esad was great. He was very knowledgeable. Everyone was very friendly and helpful.

Jarvis Jackson did an amazing job helping me purchase my very first car. He made the whole process simple and stress-free. Jarvis was knowledgeable, honest, and took the time to make sure I understood everything. I really appreciated how patient and supportive he was from start to finish. Thanks to him, I drove away with the perfect car for me. I highly recommend Jarvis to anyone looking to buy a vehicle!

I had an amazing experience with Jarvis and Micheal. Jarvis and Micheal made purchasing a vehicle easy and kinda fun. I will definitely be back when it's time to trade my 2025 Sierra 2500 AT4. If you are in the market for a vehicle, go check out Woodyin Gurnee. Don't forget to ask for Micheal or Jarvis!

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

Frank was friendly and helpful. He look up my records to make sure I was not receiving and paying for unnecessary service. He provided a coupon.

We had a great experience at Woody Buick GMC. My experience with Mike was Jarvis was great. They explained all that I need to know. We bought a GMC Acadia.
