Used GMC Sierra 2500 trucks for sale near Algonquin, 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.

This truck is the truck that all others should look up to. It rides great, will tow a house, runs smooth, and gets great fuel economy. The Allison transmission is so smooth. The AT4 looks great too.

Eduardo Del Rio helped me buy my ford explorer and made sure it was in my own liking

Great experience. Alex was a charm to work with for the truck I been wanting.

I paid over $106,000 for this truck with warranty. Do not care much about miles per gal. at that that price range. Just too much truck for me at my age.

This was my second time buying my new car at ray chevrolet and I couldn?t be happier. I was lucky enough to work with Rupe both times and he took great care of me. When I initially came in, both Rupe and Ryan did everything they could to get me in the exact car I wanted and they made my experience so much easier than I expected. During the entire buying experience, all the staff was easy and kind to work with. I am so happy with my new car and would buy here again in the future!

I bought mine in 2017, 2nd owner. It had 36,000 miles on it when I bought it, getting ready to turn a 100,000 miles, and the only thing I've had to do to it, is replace the Def heater, other than that, it's been a great truck. 👍

Excellent service even delivered the new car door to door very convenient. They made the whole car buying process very easy. I would highly recommend them to anyone who is interested in a buying a new car.

One very awesome vehicle. Checks all the boxes you need in a truck and exceeds expectations on quality, performance, and looks great ,too. Love my nre truck.

I brought my car in for an oil change and multi point inspection. the inspection dealed that I a front brake issue. Mike, the employee I dealt with describe the issue and what it would take to repair it and how long I would have to wait he offered free transportation home if I wanted. because of the distance that I would have to travel there and back to home, I opted to delight the two hours in the lounge. I had coffee and water and I was fine. Mike came in several times to talk about the repair. He also said he had a rebate coupon I could use and he pointed out. I had points in my Buick awards account that I could convert to dollars to pay for the repair. That was very good service save me money and the car is running fine

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.

My first experience at this dealership will definitely bring me back. We are so happy with our purchased! We had Alex Alverio from Sales, he was very professional & helpful, has awesome customer service & we highly recommend Alex. Thank you so much and keep it up!

Michael Stefanik is the opposite of the traditional car salesman we love to hate! He's a down-to-earth guy doing a great job.

I've owned every other American truck and this is my first GMC. I bought the 2500 HD Texas Edition. I absolutely love this truck. It's everything I could have hoped for and more. It is able to pull my 30' travel trailer with no problems. So now when we go out with our trailer I'll have no worries. The look and feel of the truck is outstanding. The 6.6L gas engine actually gets great gas mileage. It gets about the same as my Ford f150 ecoboost. Probably better on the highway. Looking at about 13 miles in the city and 15 plus on the highway. Definitely got a better truck for the price compared to any other american models with the same characteristic and options.

I love my 2021 GMC Denali 2500HD. I have gotten more complements on this truck than any other vehicle that I have owned. I get great highway fuel milage average 19-26mpg,which is great for a heavy duty truck!

Great customer service, Alex helped me out with financing ! I recommend them if you are looking for a reliable car and good financing options!

I've owned my truck for nine years now it is never once let me down. I'm about to put my first set a tires on it and brakes other than that I don't plan on getting rid of it it's never let me down and after reading all the other reviews it makes me realize they don't make them like they used to as they used too!

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

Jon David is an asset to your company he’s a gentleman and a scholar. He put a deal that I won’t forget, and I won’t forget him. My son was very happy and he treated him with courtesy.

One of the best dealerships out there with some great quality cars along with best customer service. Loved it

What a gorgeous truck, runs good, sounds good and has all of the amenities I need although I am looking forward to their next interior upgrade.

Excellent experience from start to finish. The team was professional, honest, and easy to work with. I love my new truck and would absolutely buy from this Ford dealer again. Highly Recommended!

Worked with John B for a new Bentley. He was quick and efficient, answered all my questions and the car is in mint condition. Car was fully serviced and I love it

Eduardo gave me an amazing service at the dealership and helped me find a car.

Big thanks to our salesman Brian for excellent service. Very through and he,Paul in finding the right vehicle for us. Prompt courteous service. A very satisfied customer. Highly recommend Woody and ask for Brian.

Awesome service from Huntley ford and it's salesman Rob specifically. Huge selection makes car shopping in one place easy and convenient!

Love everything about this Duramax Denali except the fuel mileage. 13-14 Mpg tops when not towing. Bought truck cause previous was stolen. Wish I still had my 6.2 High Country!

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.
