New and used 2026 GMC Yukon for sale near Mount Prospect, IL

I recently bought a Jeep from this dealership and had an awesome experience. Jamie helped me through the whole process and made everything super easy and stress-free. They were honest, patient, and really took the time to answer my questions and make sure I found the right Jeep for me. I never felt pressured, and the customer service was top-notch from start to finish. I’m loving my new Jeep and would definitely recommend asking for Jamie if you’re shopping here!

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.

Very smooth experience. Seann is an excellent young salesman. Darien will do anything to work with you. Erick, the manager is very accommodating. A++++ dealership.

I really appreciate the straight-forward buying process I found at Napleton Schaumburg GMC. Thank you to Yiannis for answering all my questions! Best- Mark
