New and used 2025 GMC Sierra 2500 trucks for sale near Eagle Lake, WI

Excellent customer service and great to work with! They even delivered my vehicle to me. Nick in sales is the best from start to finish!

So far so good! This truck is the nicest truck I have ever driven. The stance, ride comfort and options are top notch. I went from a 2023 High Country that was having drive train issues but had all the creature comforts that you would expect in a top of the line truck. With the lack of confidence in that particular models 10 speed transmission issues, it became necessary to reestablish my confidence in my General Motors product.

It was a pleasure working with Sam at Woody Buick GMC in Gurnee. The whole staff is friendly and professional.

Jarvis was the best salesman I’ve ever had and made my experience buying my new truck truly enjoyable. I highly recommend them.

Overall, the service was professional, informative and understandable from beginning to end. I came in explaining what I was looking for and that’s how it was through the process.

Kevin was very helpful and gave me a deal on the Sierra 1500 that I couldn't refuse 10 out of 10

Bill was fantastic to work with! Whole process took only a couple of hours and everyone was very helpful. Pricing was transparent and they worked with me to get me best interest rate possible.

Mike R was our sales consultant. He did a terrific job explaining everything in addition to helping us with creative financing. Kudos to the dealership!

I started here as a service customer, since then, I have bought 2 vehicles from the Lynch group. Both buying experiences were nothing short of amazing. Such a knowledgeable, low pressure buying process both times, I’ll never go anywhere else, Mopar or no car!

Chris does an outstanding job every time I visit. He is very accommodating and always aware of my needs and my time. Only place I service all my vehicles (3) and drive 30 minutes even though there are 2 Chevy dealers much closer.

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.

Excellent experience with Mr Isaiah Gonzalez. Already bought 2 cars from him and going to start to look for an upgrade soon.

Isaiah was a big help with purchasing my car and would recommend kunes to others looking to buy

We purchased a used car from Robert and he was extremely respectful and went out of his way to be helpful. We needed to get a car trailer to get the car back to Louisville Kentucky. He was able to find one and reserve it for us. Everyone at the dealership was very nice and helpful. We enjoyed dealing with everyone. We will always remember the great service and friendly staff. We will remember them if we make any future car purchases.

I am grateful to have a car service provider that can deliver good quality services. Thank you.

I worked with Isaiah, he was awesome. When I went to trade my car in. I wasn’t totally sure I would walk about with anything I wanted. But he definitely worked hard in making me leave happy! I love my Buick.

Found and fixed my oil leak and got me on my way in about an hour! Fair price and a great service advisor who walked me through everything before starting the work! Thank You Steve Buczak! Thank you also for the free car wash!

Mr Biddle is pleased with the work and professional service Solomon has demonstrated in fixing my Yukon and he helped in getting all parties involved. Thank you Solomon and crew !!!
