New and used 2026 GMC Acadia for sale near Bannockburn, IL

This dealership was great the hospitality was through the roof, though we didn't make a deal I would 100% comeback.

Great vehicle. Has great features and it is a very smooth ride. It is quiet on the road. Great gas mileage (over 28 mpg combination town and road).

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

Vanessa was very helpful when we came to purchase our car. She showed us the myGMC app and was very informative about all of the perks and points system.

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.

Best experience I've had when purchasing a vehicle. Everything was handled quicky and professionally with no pressure to consider anything other than what I had asked for. I was completely satisfied and would recommend this dealer and my sales associate Larry.

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

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

Very smooth experience. Seann is an excellent young salesman. Darien will do anything to work with you. Erick, the manager is very accommodating. A++++ dealership.

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

Most pleasant waiting room anywhere and the friendliest service people.The mechanics always attempt to fix problems before they start. Also wait time ia always fair.

Great Cars and also good service. Vincent Vega was very helpful thank you Vincent for all your help. This is our third car from Castle Buick GMC. We loved thank you .!

Expectations were set and met on a Saturday with college football on. Two separate seating areas in case you wanted the option to watch something else. There's also a kids' area if you have a little one who needs to be entertained for the time you're there.

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.

Jamie and Jonathan were very friendly and helpful. Jamie took a lot of time with us as we test drive the Buick Enclave and asked a ton of questions. The buying process was amazing. Jamie gave us a great price and didn’t spend a lot of time trying to sell on products we didn’t need. The finance of the car was extremely fast. They sent me a link to start the process online so when I arrived I was fully approved and just needed to align on the term and how much I was financing. Overall I would recommend this dealership for your next purchase.

They make you very comfortable with the process of value of trade in to purchase. I recommend Palmen for any future vehicle purchases. I'm very pleased with them.

Amazing as always! Paul and his team always take care of me and the process is efficient.

Excellent service Professional service Quick service Polite customer service Excellent customer communication Very detailed repairs

We had an incredibly smooth and pleasant experience at this dealership from beginning to end. The entire process was seamless from start to finish. Every staff member we interacted with was helpful, courteous and professional. Buying a vehicle from Seann Omara was particularly wonderful— he is knowledgeable, helpful, and genuinely committed to making sure we got the best deal possible. We left very pleased and would happily recommend Napleton Buick GMC to others!

Jamie was great in helping me with the purchase of my GMC Terrain. He made me and my family feel comfortable during the whole process. I believe he worked hard on my behalf to get the best payment for me not his commission. HE was direct and straightforward in explaining everything about the purchase while answering all questions. I would recommend him to other people besides my family.

I purchased a 2023 Genesis Gv70 Form Napleton Downtown. I ordered the vehicle and it arrived months later. The whole process was seamless. I got the exact deal I wanted.
