New and used 2026 Buick Encore GX for sale near Oak Brook, IL

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.

Great car and nice for trips or late night drives with friends or going camping in the woods or going with family places like stores

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. They went above and beyond to ensure I got the best deal and left completely satisfied. If you’re in the market for a premium truck, I highly recommend the GMC 2500 Denali and working with Tony. You won’t be disappointed!

I wish it did consume less fuel. Also, the engine noise that you can hear while driving, give a sport feeling so if you want just luxe and confort, it may distract you. But It's a very good car, new modern look and confortable....

Tony was our salesman and he took care of everything. Great experience thanks again and hopefully we get to see you guys again soon. The finance guy was great as well.

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.

Todd was very helpful and made sure my car was pulled inside when leaving as it was very slippery outside

The sales staff is incredibly helpful but there’s one guy who stood out to me he was tall had curly hair & a beard. I don’t remember his name but I heard someone calling him Izzy. He was very respectful and you could tell he has a strong work ethic, that guy definitely deserves a promotion. I always see him working so hard at the dealership.

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.

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

Very quick, good communication . Honest. Feel like you can trust them to be fair. Happy with results. Will return for other needs if they arise in future.

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.

We've worked with Tony before & he is very knowledgeable & knows just what we like.

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.

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.
