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

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

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!

Thank you to the service team for your getting me all set for my roadtrip!

I have brought my vehicle in for every oil change I have needed. Always courteous and professional, my car gets a diagnostic check every time and is freshly washed. I like that the Service Department send out coupons, and making an appointment is easy online or with a phone call.

Frank was friendly and helpful. He look up my records to make sure I was not receiving and paying for unnecessary service. He provided a coupon.

Brian at Marquardt service department was extremely helpful to get my car all ready for winter with a new set of tires. I appreciate having a great dealership near by to handle my car needs.

My salesman Esad was great. He was very knowledgeable. Everyone was very friendly and helpful.

I purchased a 2023 Genesis Gv70 Form Napleton Downtown. I ordered the vehicle and it arrived months later. The whole process was seamless. I got the exact deal I wanted.

The sales staff is incredibly helpful but there’s one guy who stood out to me he was tall had curly hair & a beard. I don’t remember his name but I heard someone calling him Izzy. He was very respectful and you could tell he has a strong work ethic, that guy definitely deserves a promotion. I always see him working so hard at the dealership.

It was amazing. Efficient, pleasant, and quick. We love our new Buick. We usually do not look forward to the process of purchasing a car. It was actually enjoyable.

Excellent service Professional service Quick service Polite customer service Excellent customer communication Very detailed repairs

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!

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!

Thank you Jamie for an easy purchase on my 2026 2500hd Denali. It was one of the easiest car buying experiences ever!
