Used GMC cars for sale near Sycamore, IL under $1,000,000

Dion went above and beyond to help me get into a car that was best for me. I will keep coming back- this my second car from this sales person!

Good afternoon everyone, yes, I’m a lady and I’m an owner of a 2017 GMC Sierra 1500 Denali, it has a V8 motor fully loaded sunroof & also it has heated seats & steering wheel for the cold winter months & in those hot summer months you have A/C seats nothing better than that am I correct? It’s been times like that wouldnt trade for the world!! So for all you ladies who think BIG TRUCKS are just for men, go out there & buy one have them put on some electronic slide in/out rails & go out & show the shows the boss!! lol 😄 I’m out looking for a new one now either a 2500/3500 pearl white

Great dealership...totally customer focused. Our salesman was Paul F... tremendous attention to detail. Traded in a Velar for a CPO Velar...fair pricing for both the trade and CPO. Highly recommend.

Am in disbelief every week at the Gas Pumps. Thou a big truck, mileage per gallons are 18 +. Last week it was 22.8. This week 19.78.

What a great team, very impressed with the service and effort they put into getting me in my new Jeep. Thank you Kunes Family

Stong engine and smooth! Highly recommend for familys or someone who likes a smooth truck. Purchased new and have had zero issues since then. Love it!

It was amazing. Efficient, pleasant, and quick. We love our new Buick. We usually do not look forward to the process of purchasing a car. It was actually enjoyable.

Nice styling,interior has a new design dash which is beautiful and convenient,safety features and cameras are great and easy to used and the active cruise is awesome.

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.

Great truck to own. The 2023 GMC Sierra Denali with the 6.2L engine delivers excellent power, smooth performance, and a refined driving experience. The ride quality, interior comfort, and overall build quality are outstanding. I have had no issues whatsoever, and it has been a reliable, enjoyable vehicle from day one. I would highly recommend it to anyone looking for a premium full-size 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.

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

This truck has a jerk when changing gears sometimes. I enjoy the truck overall easy to handle and comfortable. Drive with ease sight is good when driving.

Purchased a Camaro from 900 miles away. Anthony and Dan did a good job and made the purchase easy. They also assisted in shipping the car to me.

I love it the look the interior mine is a red one and it looks so good and it’s my baby and it runs so good and the technology is off the chain

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

Martin Chevy in Crystal Lake is an AMAZING dealership with AMAZING people working there. From searching the right cars, making the purchase, financing and service, this place rocks it all!!! Highly recommended!!!

Got the duramax diesel and getting 24 city and 32 highway is very good. Truck drives nice and is very comfortable. My 2 issues with this truck is the backup camera at night is useless (very dark) and interior lighting is not very good. You would have thought a 78k truck would have footwell lights, but it doesn’t.

Bought a car for my daughter tim was great would definitely go back for my next purchase

2024 GMC sierra 1500 duramax 3.0 is great truck. Great ride and great MPG. 100% recommend to any prospective buyer. Love the truck and how it perform.

It was my first time buying a car and Cruz & David were very nice and got me a great price it was a great experience and in the future I would definitely go back and purchase another & I will recommend the place to all my friends and family

2021 GMC sierra 1500, 5.3, crew cab 4x4, 21000 miles. brakepad monitor lites up. dealership says needs brakes and rotors in back. one mo. on warranty. our rural roads dirty up the monitor. Needs new monitor. brakes look great to me. No noises. dealer says parts on order GM strike. Can't replace myself cause of computer...

Andrew Doyle at this dealership was amazing to work with. He was soft spoken, detailed yet concise. He was influential in making a deposit for a purchase. I had to pull out later for other reasons. But I give high regards to Andrew’s work.

The Yukon checked all of my needs, I have plenty of room for my children and my Great Danes. I enjoy driving the Yukon and how it handles, overall love this vehicle!

The staff is honest, knowledgeable and professional. The sales contract was straight forward, they explained everything and they were very fair. I will definitely come back every time I need a car.

This Yukon has all the bells and whistles. It is a joy to drive, the drivers area is like a cockpit with everything at your fingertips.

Mike Medina took care of me and my families needs and I couldn’t recommend a better place or person to buy a car from!

This car is a fabulous car for family and traveling. It is roomy, has capacity for kids and sports gear, and is safe. I have been rear ended twice in a Yukon and there was minimal damage to the Yukon and extensive damage to the other vehicles.

Olivia was the best to work with! She’s so friendly and fun. She worked with me and went over several options and helped me find my dream car! Noah was great too! I feel like I got such a deal!

I have enjoyed my vehicle. It is comfortable and drives very well. I like the color also. It is very roomy, takes off fast and the safety features are very beneficial.

Easy purchase experience, would recommend to anyone looking for a new car. Everyone there was friendly and made the whole process as smooth as possible

excellent service Joe worked with my third party warranty company to get the repairs covered i really appreciated all he did for us i am very gratefully for all of the employees hard work.

I have a 2023 GMC Sierra 1500 Denali with the 3.0 Diesel engine. I have 20,000 miles on it at the time of writing this. Never owned a diesel before and now i don't think i will own another one without it. I LOVE the engine in this truck. Only complaint would be that it likes DEF fluid while towing so pick up some extra DEF before you head out to tow something. Put about 8K miles on it this summer without adding any DEF fluid. seems to use a little more in the winter or when towing. Very quiet for a deisel and the fuel economy is awesome. Driving 70 mph down the freeway this truck gets about 30mpg, Drive 55mph on regular highways and this truck gets almost 40mpg. All around driving for me is about 26mpg. I used to fill up twice a week with my gas motor and now only once a week. Wireless Apple Carplay works great and the voice texting and mapping is a big plus. I also have the new SuperCruise feature which is awesome. Get on the freeway and set the supercruise on and the truck drives itself until i get to my exit (about 28 miles from home to work). Bose stereo is out of this world and all the storage is great to. I have a swingout bed toolbox, aluminum roll up tonneau cover, Lighted black GMC front emblem, Gloss Black 22" wheels, All Black decals and my dual exhaust bezels are black as well. I rotate the tires and change the oil every 5,000 miles. Couldn't ask for a better truck. Might get the ultimate next time as that has the messaging seats which i kinda wish I had.

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.

Excellent and reliable, only thing buyers have to do is buy a AFM disabler that you can stick into OBD2 port to avoid lifter failure (longer story, nobody wants a V8 to run in V4)
