New and used 2026 Buick Encore GX SUVs for sale near Addison, IL

We worked with Brian Newcomb to purchase a new 2025 Buick enclave. From the moment we walked in the door, we felt at ease and were comfortable. Brian was down to earth, honest, and personable. He was knowledgeable and was able to answer all questions. We highly recommend Brian. He made the whole process headache free and easy!

Kim was incredible in helping me get my repairs covered by my extended warranty! Details of service were provided and car was ready when needed.

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

Needed key fobs replaced. They were ordered and came in within the next couple days. Scheduled the service appointment and all was completed within two days. Have received great service upon all my visits.

Ernie was a great salesman he walks you through eve step of the process

Fast professional easy to work with didn't feel pressured this is my 2nd purchase from them I will definitely go back when it's time for another purchase.

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 had major work done on my car and I couldn?t be happier with the turnout. I had my transmission replaced along with a couple other issues on my 2017 vehicle. It took a while for the entire thing to get completed, but I was given status updates throughout the process. I picked up my vehicle late last night (5:45 pm). I was surprised the service manager was still there and he took the time to go over everything that had been done to my vehicle. The total price was slightly lower than what I was I was told it would be at the start. I was very happy and wasn?t expecting that. My car is driving great today and so far I?m extremely happy with the result from my service experience. I?m very appreciative of the help I was given and the customer service I received. Thank you Justin and everyone who worked on my car. ?

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.

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

Somehow the rear window wiper blade cover on my 2019 Buick Encore went missing.... Being a long-time friend and customer of Mike's, I went to his GMC service center for replacement, and was grateful that Bill Haggerty replaced the missing cover without charge! As always been my experience, GREAT service and GREAT dealership! ...Tom Noble
