Great experience. Until it came to finance department. Finance manger was very nice. But took two hours to get to the finance department, which only took 5 minutes to sign the paperwork. Seemed like a very busy dealership, would suggest additional financing employee to speed up the process.

One of my better experiences at buying a new vehicle.
One of my better experiences at buying a new vehicle. Rogelio was very knowledgeable on the truck I bought, explained and showed me how to use all of the new features the vehicle had to offer. Took the time to setup and explain how the app worked on my phone. Excellent experience in my view. Highly recommend Rogelio if you’re looking for a new vehicle.

We had a great experience at Woody Buick GMC of Naperville. Our sales rep Daniel was very helpful. I came in to purchase a new GMC 2500 HD. He was knowledgeable about the truck, and he also brought it to the house to make sure it fit in the garage. My wife showed up as we were finishing up and also purchased a new Buick from Daniel also. I highly recommend Daniel when you are ready to purchase a new vehicle.

I came across several options in the area for a new GMC but Woody's was far and away the right choice. Daniel greeted me when I walked in the door and made me feel comfortable until I drove away in a new Yukon the next day. The entire experience was first class from the selection process through the post purchase follow up. I will recommend my friends/family/colleagues to work with Daniel at Woody's on all future purchases!

Even my husband enjoyed chatting with him. He didn't make me feel any less valued because I wanted to be the one to work with him and make the decisions. I would definitely come back and request Dan the next time I purchase a new car in the future.

There was a rude young male employee who bumped me hard as we entered the same part of the dealership at about the same time. I was so offended that he did this. I told my salesman about this episode (Tim whose professional caused me to buy the Arcadia Denali). The manager knows who this CLOWN is. My spouse & I came back 3 days later and bought this SUV. Employees like this will cause Woody Buick Dealership to lose business.

Crystal Santana and Xitlali Lopez invested so much time and care to answer all of my questions via email-because I simply can’t use the phone having a daughter with autism who normally shouts in the background. I was able to conduct all business via email throughout the morning enough to wear when I arrived. I already knew everything I needed to know. Dell greeted me at the front and got the car ready. I went for a ride and I already knew I was going to buy it. He was able to answer all of my questions provide me with all of the information, he took his time, he was patient with my child and he understood my needs. I have been looking for a car for over a month and they’re the first to have even really given me the time of day. I am very happy with my purchase content with the service that I received thank you and wishing you lots of business to come!

In the 40 years, I have been buying cars, and being the general manager of a car dealership, this dealership has the worst salesforce I have ever dealt with. If you are trying to buy a car from the dealership online, forget it! The sales people are rude and do not get back to you. I asked for a manager to call me and they just blew me off. What a horrible experience.

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!
