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.

It was such a good truck honstly the greatest thing I have ever drove in my entire life I am so happy that I have been blessed with this being my first ever car

Bill was fantastic to work with! Whole process took only a couple of hours and everyone was very helpful. Pricing was transparent and they worked with me to get me best interest rate possible.

One of the best truck buying experiences I've ever had. Worked with Daniel and Mari via email to lock everything in and set a time to make the drive down. The team was supper responsive with questions and details about the truck and the purchasing process. When I arrived, Jamie met me at the door and had the truck squeaky clean and ready to go for a test drive. We went over the vehicle features and finance had the paperwork ready to go by the time we were done. All in all, I was in and out quickly but never felt pressured. At the end of the day, it was worth the drive to work with Jamie and the rest of the team.

Juan was excellent to work with, we quickly agreed on a price, the vehicle was cleaned and ready to go by the time the paperwork was complete. Highly recommend.

Chris Lahey was an exceptional person to deal with and got us the car of our dreams!

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.

Excellent as well as timely service. However, was not told in advance that paying with Credit Card would have a 3% fee.

Super honest deal. Used car as advertised, no surprises, no pressure. They detailed it for us while we did the paperwork.

Quick communication and smooth process. Ov Perez was very professional, helpful salesman who made the sale a great experience.

alex gave me a great deal on our new buick..... thank you so much alex.

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

Thanks to Woody Buick GMC for another great experience in purchasing a new SUV. We’ve had the pleasure of leasing and purchasing 8 vehicles through Brian Newcomb over the years and he never disappoints! He always finds us just what we are looking for and makes sure we walk away as happy customers. If you are looking for a new vehicle, Woody Buick GMC is it!

Chris does an outstanding job every time I visit. He is very accommodating and always aware of my needs and my time. Only place I service all my vehicles (3) and drive 30 minutes even though there are 2 Chevy dealers much closer.

Bought a car for my daughter tim was great would definitely go back for my next purchase

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.

Jamie was an outstanding person to work with. Patient with us allowed ro drive several vehicles and not pushy

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

Nathan and Kevin was great. They made the car buying experience very simple and made sure that all of my questions were answered. Im very happy with my new Envista.

Easy to schedule service. They shuttled me to my home and back and were super fast and on time!

Great people. Great service. Highly recommend Erick and team. They will give you a solid deal
