Used GMC Sierra 2500 trucks for sale near McHenry, IL under $799,997

This was my 6th Buick Envista purchase with Manny from Woody is very knowledgeable and professional.

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!

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.

Love my GMC. Owned a Chevy and this absolutely beats it hands down. Never had any issues. Inside is very comfortable and can't imagine driving anything else

This is the first diesel I have owned. The power is amazing and I really like the room inside the cab. This truck is a beast... Love it!

I arrived late to pick up my vehicle. Fortunately one of the Service writers noticed my arrival as he was leaving for the night. He came back to the dealership and secured my vehicle and billing. Great service.

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!

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.

Our sales person, Joel Storm, was friendly, informative, energetic, and interested in what I needed in a car. He helped me pick out the right vehicle for my needs.

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.

Gary is an honest, small town, salt-of-the-earth guy with quality vehicles and solid customer service. Dump your other dealership and come visit Dixon Auto Sales for your next car purchase. Pro tip, bring Gary a Mountain Dew and stay for the conversation.

This truck would help me thru out my needs I and my family love this beautiful truck, there is no better place for me to shop than the Paso Robles Chevrolet I highly recommend them

I would highly recommend this dealership. They were honest, not pushy, patient and understanding. Thank you Car Corral for your everything you did for us.

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.

I purchased a truck from them in january 2022, unfortunatly the truck broke down on my way home, it first started with a coolant leak. after my mechanic fixed the leak he noticed the truck was getting a lot of missfires and no codes coming out, they had already replaced fuel bump, and catallic comberters( which the old ones were super burned out) this was now a month later after i had purchased the truck and yet after doing all that work it still didnt run right.... called motorsource to let them know what had happen with it. they were aware that it broke down since day 1 of driving it.. we both agreed that the vehicle needed more work and decided to bring it back to motorsource.. it was a really bad experience at first but these guys understood that the truck was bad or needed work to be sold and we were able to replace it for another truck that would work and didnt have any issues.. Over all experience was great.. these guys were super honest about the situation and were willing to help another business owner with their bussiness needs.. HIGHLY recomend.

I love my Denali. Beautiful truck inside out. When I drive down the road all heads turn. I couldn't have made a better choice. That's Cortez for you good service.

I purchased a car here couple months ago. Very happy with what I got. The car is in amazing shape, taking in consideration that it is pre owned. Andrei, who is the owner was very welcoming. He helped us with the financing and got us an amazing deal. Overall, great experience and highly recommend this place!

This truck is everything I wanted! GMC, 4x4, Lifted, Low milage. It's going to be great for my hunting and 4 wheeling! I love it!

Anytime I call and let them know that there’s a problem with my vehicle I bring it in and they take care of it. Found out yesterday that there’s something wrong with my transmission. Thank God for their warranties. I have a special needs son and I need a bigger vehicle and because of them I have that bigger vehicle.

everything i wanted in a vehicle, power ,comfort and the looks . great looking truck with lots of power . Diesel model of the denali HD

I had a really great experience with the car dealership, Eduardo helped me a lot with trying to buy a car that is a Camry, he is really good at trying to explain everything to me details to details. He has great spirit and energy!!

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.

They really made this a smooth experience. Especially when it came to the actual purchase of the vehicle. We dealt with Nick as our sales person and he was great at communicating with us and insuring any needs or concerns were addressed.

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.

Every one I met here were extremely nice and very welcoming, they answered every question I had and I would definitely recommend this place for vehicle shopping.

Could never buy another truck after owning this. I'm only getting rid of it cause I ordered a 2021. Hands down, this is the best of the best!!

I live in Michigan and purchased a vehicle recently, sight unseen. Jeff was very pleasant to work with. I had the car delivered and found it just as he described. I think I got an exceptional value. The vehicle was delivered to my house earlier than promised.

Meets my needs. Plenty of power. Lots of room. Hauls and tows like a dream. Very nice and stylish truck considering that it is a W/T.

Very friendly family run business with fair prices. I was very happy with my vehicle purchase and would not hesitate to buy from them again. The purchase process was the quickest I have ever had (less than 30 min).

We bought our GMC 2500 HD gas 6.0L extended cab last spring to pull our 9k lb 5th wheel. We pulled it for about 6k miles with abslutely no issues. It pulls great, a bit slow off the line, but it will get going if I put my foot down -no issues on the highway. It'll do 70 all day long pulling our portable house. We get about 8 MPG towing and 17 empty in rural areas. No doubt the diesel would haul better and get better MPG, but for an extra 30-40 cents/gal, that doesn't make sense for us. This truck has much better fit and finish than older GM vehicles we've owned. In fact this our 1st GM since our 2000 GMC Safari (that was a money pit). We love the look of the extended cab with 180° rear doors. The rear seat is the same size as the newer 4 door. To us the truck looks classy. It has style and rugged looks without being over the top. The next 2 generations are just stupid big. Seems like the bigger the grille the more compensation. Basically, I highly recommend this generation 2500. It does everything we need it to do and looks good doing it.

Great service from Eduardo. I don’t much about cars but he helped find one that best fit my needs.

Truck was bought specifically to our travel trailer. We have to wait for 1000 break in before we can tow the trailer. So far the truck is very quiet, smooth running, & comfortable to drive. We were pleasantly surprised at how much interior storage space is available. Having the bed steps before rear tires and in the bumper sides is very nice. Bed rails are even with my shoulders so the steps get used a lot.

If you going to purchase a new vehicle. Please ask for Tristen Cairo at Gordie Boucher. He is outstanding! I have purchased 6 cars from him over the years. He works for you! He listens and. Gives you 200% of his dedication to you. Ted Poulos

Great service and quality car! Jon Golm was a great sales guy. Looking for safe reliable car for my granddaughter and he delivered. Awesome experience!

I'm so thankful to have worked with Timothy Maloney. He was super friendly and knowledgeable. He really took the time to understand what I was looking for and helped my find the car that I absolutely love!
