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

Buying my Camaro from Castle Chevrolet in McHenry was an
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.

The entire team at this location far exceeded our
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!

One of the best truck buying experiences I've ever had.
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.

Had a great experience leasing a 2026 GMC Sierra 3500
Had a great experience leasing a 2026 GMC Sierra 3500 from Woody Buick GMC. Started with an online inquiry and we texted and called, negotiated the deal and we went in and test drove the truck, they reviewed our trade and we then learned about the new truck’s features and then signed and left. All within 1-1/2 hours. Jarvis was our salesperson and he was super nice and knowledgeable. He really made things easy. We will be back when we are in the market again as we felt at home! Great people to work with for sure !

My sales person at Castle Chevrolet was Tony Twall. He was awesome to work with. He answered all my questions and was very knowledgeable.
