New and used 2026 GMC Acadia for sale near Tower Lakes, IL

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.

I recently bought a Jeep from this dealership and had an awesome experience. Jamie helped me through the whole process and made everything super easy and stress-free. They were honest, patient, and really took the time to answer my questions and make sure I found the right Jeep for me. I never felt pressured, and the customer service was top-notch from start to finish. I’m loving my new Jeep and would definitely recommend asking for Jamie if you’re shopping here!

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.

I and my wife only use the dealer's services for maintenence and repairs. We are always satisfied with the quality of the repairs and the friendliness of the office technicians

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

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.

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.

Thank you Jamie for an easy purchase on my 2026 2500hd Denali. It was one of the easiest car buying experiences ever!

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

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

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.

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.

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

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

As always, service and service reps were great-wonderful dealership and service department?have purchased cars from dealer for many, many years and will continue to do so.

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.

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!
