Used GMC Sierra 2500 trucks for sale near Forest Park, IL

So refreshing to finally find a honest and fair dealership. Jimmy my salesman was the BEST. Great communication, help and he made the whole purchase experience Great.

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.

Very quick, good communication . Honest. Feel like you can trust them to be fair. Happy with results. Will return for other needs if they arise in future.

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!

We've worked with Tony before & he is very knowledgeable & knows just what we like.

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.

Jackie was great! She was helpful and knowledgable. She seemed interested in helping me find exactly what I was looking for. I would highly recommend her.

Violeta and Tim did great job with whole process Very transparent and very accommodating and was able To get me into the car I wanted and even fed us lunch highly recommend Violeta as sales person and countryside nissan

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

Our salesman Brian Newcome was polite, professional, knowledgeable, and personable. We felt he answered all our questions, and explained the process so it was understandable. When you buy a car you wonder did I get a good price and make the correct decision, with Brian there was no concern about that at all. I would recommend Brian and the dealership to my family and friends.

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.

From the moments I got in the dealership until I left I was treated very nice and very welcomed. I looked at Lexus RX and end up buying it because I felt comfortable and car is clean with good competitive price. Very recommend

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!

Was a pleasure doing business with these guys. Gorgeous showroom with an amazing selection of cars. True enthusiasts here. Got a great price on my car, they offered a fair price on my trade. Were super up front on all details of the car and the deal. Fast and efficient. I look forward to buying again - these guys are more like a fine automotive concierge service than a dealership! Keep it up fellas!

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.

Frank was friendly and helpful. He look up my records to make sure I was not receiving and paying for unnecessary service. He provided a coupon.

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.

All the employees are super helpful and genuine. Great experience from start to finish! Definitely recommending to anyone who asks!

Great power and yet great economy. Love the safety features with the cameras and side vehicle warning. Camera that shows side of vehicle, including trailer when turn signal is on is great. Also appreciate the bed camera for hooking up gooseneck trailer.

The staff is very experience and professional. The estimate for repairs were in line with the services. I compliment the facilities with free coffee, water and soft drinks.

Very comfortable buying experience! I had never purchased a vehicle completely by myself belore, so I was quite nervous going into the process. D'Arcy Mitsubishi and Jesus Rodriguez helped me through everything, showed me my options, let me test drive three vehicles, answered all my crazy questions, and made the purchasing process simple. Thanks to them, I absolutley LOVE my new Mitsubishi!

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.

If you’re not looking to be served champagne and want a simplified buying experience this is the place to go! The no haggle pricing takes some of the anxiety out of the car buying experience, and if you cross check the vehicle on cars.com it will directly tell you if you’re getting a good deal or great deal or fair deal. We purchased a Porsche Cayenne from them and Dan and Brian were awesome! Thank you!!

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.

Great Prices, staff and selection of vehicles to choose from! Thanks Jose for an amazing experience

When looking at price point vise equipment, This is your truck. I looked at every 2500/3500 on the market, same vehicle equipment and price. I chose the Duramax.. HP, Torque of this Diesel, truck equipment that the SLT price point had everything that I wanted for safety, appearance and comfort, none other came close. This is your truck...

I have never bought a car online before let alone bought a car without even seeing it or driving it. I saw a Bentley Flying Spur for sale at Chicago Auto Gallery. I called and spoke to a salesperson named Steve. From the first hello on the phone until we closed the deal and the car was shipped to me Steve was fantastic. He did everything possible to ensure that I was satisfied with the car and the deal. Now here's the extra part that I was even shocked at myself. Once I got the car, I drove it and after 5 miles some of the lights came on such as check engine, ride height, traction control and ABS. I was initially immensely pissed. I called Steve and said you might want to get ahold of that driver who delivered this car and tell him to take it back. Steve suggested I take it to a certified mechanic near me and have it looked at to see what was the problem. Apparently when one light goes off, it triggers more lights to activate. I had it looked at and to fix the car right it was going to be over $3000. Steve took care of it and the dealership paid the whole bill. In my mind that was the most solid thing to do and he did it. He could have argued and tried to avoid it or said no, you bought it, you fix it. They did not do that to me. I'm in Pittsburgh and they are in Chicago. I know I had rights and could have just sent it back but I wanted that car and they fixed it for me. I appreciate everything they (Steve) did for me and I would definitely purchase another vehicle from them. Thank you again Steve and Chicago Auto Gallery.

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!

Great service! I felt welcomed and at ease. The staff were very friendly and I didn’t feel pressured to buy!

Came in to service my Acura TLX, had a great experience with Carlos and they also showed me a Type S they had in stock. Was a little out of budget for now, but very reasonable price for new brakes and rotors and a decent bit cheaper than Acura themselves.

The dynamic duo strike again! Corey and Tito came through as always to meet my wants, my needs, and my budget! Always professional and knowledgeable and willing to go that extra mile when needed. I couldn?t ask for a more dedicated Team!

I always love coming here for service. Carlos and team are all very friendly and thorough. They have always taken great care of my car and me.
