New and used 2026 GMC Sierra EV trucks for sale near Deerfield, IL

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.

Brought my my car in for normal service and Mark Took care of me. He was great. He pulled up my history on my car and made recommendations for what I needed and explained everything they would do. Also gave me approximate cost of service which was Very close to his quote. Work was done very quickly. Just a great experience. I will be back for my next service when needed. Also everybody that works there were very friendly .

I had major work done on my car and I couldn?t be happier with the turnout. I had my transmission replaced along with a couple other issues on my 2017 vehicle. It took a while for the entire thing to get completed, but I was given status updates throughout the process. I picked up my vehicle late last night (5:45 pm). I was surprised the service manager was still there and he took the time to go over everything that had been done to my vehicle. The total price was slightly lower than what I was I was told it would be at the start. I was very happy and wasn?t expecting that. My car is driving great today and so far I?m extremely happy with the result from my service experience. I?m very appreciative of the help I was given and the customer service I received. Thank you Justin and everyone who worked on my car. ?

I have to say that Ryan and the staff at Napleton sure know what they are doing. They were quick to answer any questions I had and took away the fear of buying a car! They were friendly and knowledgeable and NOT pushy like most car salesmen. I walked away with a vehicle that I love and a great experience!! Thank you Ryan for all your help!!

The entire team at this location far exceeded our expectations! Our sales consultant Sandi was extremely easy to work with, and he had our best interest in mind when working on a deal for a new truck. When it came time to financing, Alex ensured we got in and out with exactly what we needed. He provided us personal stories bridging to his recommendations that help guide my wife and I in a direction that surpassed what we originally had in mind. Finally, throughout the visit Edgar and Manny ensured we felt comfortable as we worked though a deal that would ultimately have us driving home without any doubts in a vehicle that can grow with my family. They were the cherry on top to an already excellent experience. Thank you from the bottom of our hearts for such a great team!

Made a online appointment came in and they did a oil change and tire rotation. Happy with the service.

Ernie was a great salesman he walks you through eve step of the process

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.

Alex is the man to see he knows his vehicles. Easy to talk to great customer service, he finds the vehicle you need. Alex help us in every aspect. Would highly recommend this dealership and recommend you all to see Alex.

Thank you very much Daniel Rico for the help of yours. Making our purchase easy and quick

Andrew Allen was amazing partner in my purchase so patient and great knowledge related to my Encore and Buick. The walk through was very thorough even providing me with his direct access for all future questions.

We bought our new Acadia from Mike Rancharran at Gurnee GMC, if you are looking to buy a car ask for Mike, he will do what he needs to do to get you a great car at a great price. What’s nice about the dealership is you deal with one person not 3 or 4, they are not pushy and if they don’t have what you are looking for they try to find the car you want. Thanks Mike !!

Super honest deal. Used car as advertised, no surprises, no pressure. They detailed it for us while we did the paperwork.

Easy to schedule service. They shuttled me to my home and back and were super fast and on time!

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
