New and used 2026 GMC Sierra 2500 trucks 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.

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 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.

This dealership was great the hospitality was through the roof, though we didn't make a deal I would 100% comeback.

I was very impressed from start to finish. Shelley Barr & all her associates were very knowledgeable, kind, helpful, and honest. I appreciated everything they did to make buying a new car enjoyable and not stressful.

Our salesman Brian Newcome was polite, professional, knowledgeable, and personable. We felt he answered all our questions, and explained the process so it was understandable. When you buy a car you wonder did I get a good price and make the correct decision, with Brian there was no concern about that at all. I would recommend Brian and the dealership to my family and friends.

Expectations were set and met on a Saturday with college football on. Two separate seating areas in case you wanted the option to watch something else. There's also a kids' area if you have a little one who needs to be entertained for the time you're there.

I had an amazing experience at Zeigler Buick GMC of Lincolnwood! From start to finish, everything was smooth, professional, and stress-free. Mariya was absolutely outstanding. She was knowledgeable, patient, and genuinely cared about helping me find the right vehicle. She took the time to answer all my questions and made sure I was comfortable every step of the way. I ended up purchasing a 2026 Buick Envista, and I love it! The car is stylish, smooth, and exactly what I was looking for. Mariya made the entire process enjoyable and easy. If you?re looking for great customer service and a team that truly takes care of you, I highly recommend Zeigler Buick GMC of Lincolnwood and definitely ask for Mariya!
