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.

I and my wife only use the dealer's services for maintenence and repairs. We are always satisfied with the quality of the repairs and the friendliness of the office technicians

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

Anthony greeted me in the parking lot and was friendly and professional. He quickly brought the car out that I wanted to see. Negotiations were very fair and the paperwork was done in a timely maner. I love my new/pre-owned HyundaiTucson. Thank you Anthony and the team! I'll see you again when I need my next vehicle.

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!
