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

I recently purchased a 2026 GMC 2500 Denali, and it has exceeded all my expectations. The truck is powerful, smooth, and built for both work and comfort. The luxury interior, advanced technology, and attention to detail make every drive enjoyable. Towing capacity and performance are top-notch—perfect for heavy-duty needs without sacrificing style. A huge thank you to Tony Gullette, who was an outstanding sales professional. Tony made the entire process easy and stress-free, providing clear answers, honest advice, and exceptional customer service.

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

Elliott was incredibly helpful. He had patience and don’t oversell. This allowed us to find the truck that we wanted vs feeling like we were pushed to make a decision. Would buy from Elliott again.

Purchased a Camaro from 900 miles away. Anthony and Dan did a good job and made the purchase easy. They also assisted in shipping the car to me.

Great people to work with. Very professional, courteous, helpful and thorough. They follow through with all of their commitments. The trade process was straight forward and was just as agreed.

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!

Always a great and personalized experience! Definitely a VIP experience with every transition and handoff throughout the entire experience. Dominic and the rest of the team personalize the experience, and go above and beyond. The follow-up is next level between the technology and personalized touch. They have a loyal customer in our family!

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.

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.

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

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

Great service. The service department was courteous and friendly. My car was serviced and ready to go in a reasonable amount of time. I was very satisfied.

It was amazing. Efficient, pleasant, and quick. We love our new Buick. We usually do not look forward to the process of purchasing a car. It was actually enjoyable.

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.

My service advisor, Michael, did a great job of communicating the progress of my service appointment. Not all the necessary parts were in stock after the diagnosis, but he kept me apprised of the status of their arrival and made sure I had a loaner when they came in. The technicians did a great job and returned my vehicle in great condition.

We walked in looking for a new or lightly used Cadillac. Coach Novak approached us and was absolutely fantastic. He was right he isnt a typical salesperson. He wasnt the typical slick talking, fastmoving stereotypical sales guy. He was respectful of my wife and my time and our needs. We got an great deal on a beautiful Cadillac. Thanks Rizza and Coach for all your service and attention in our new purchase.

Jackie was great! She was helpful and knowledgable. She seemed interested in helping me find exactly what I was looking for. I would highly recommend her.

Mike Lorenzo, Kevin O Boyle D Arct Luke Stiller were the best people I?ve ever dealt with in a car dealership and I bought over 20 cars

Wonderful customer service, amazing financial people, overall amazing experience! I’ll definitely be back again

Brian at Marquardt service department was extremely helpful to get my car all ready for winter with a new set of tires. I appreciate having a great dealership near by to handle my car needs.
