Used GMC Sierra 2500 trucks for sale near Wilmette, IL

Very competitive price and willing to negotiate. Good overall experience. Edwin was a great sales person and he has followed up already a few times to ensure we are happy and have everything we need. Would highly recoomend.

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.

Great people to work with. Very professional, courteous, helpful and thorough. They follow through with all of their commitments. The trade process was straight forward and was just as agreed.

We had a fantastic experience working with Lance at Countryside Nissan! He was honest, helpful, and truly went above and beyond to accommodate us—especially since we were driving in from 3 hours away. The SUV was exactly as described, runs like a dream, and was priced very fairly. Everyone at the dealership treated us with kindness and respect, which made the whole process smooth and enjoyable. We couldn’t be happier with our purchase and will 100% shop at Countryside Nissan again. Thank you for making this such a positive experience!

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!

Todd was very helpful and made sure my car was pulled inside when leaving as it was very slippery outside

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 experience overall. I was offered a fair deal without any pressure or unnecessary upselling. Chuck Fioravanti was straightforward, answered all my questions clearly, and made the whole process easy and stress-free. I?d definitely recommend this dealership to anyone looking for an honest and smooth car-buying experience.

Elliott was incredibly helpful. He had patience and don’t oversell. This allowed us to find the truck that we wanted vs feeling like we were pushed to make a decision. Would buy from Elliott again.

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.

Beyond happy with my purchase here at Oswego Motors, Jared & the team are great! I Love My BMW

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.

Really outstanding service. Made transactions very easy and fast. People working there super friendly and courteous.

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.

My salesman Esad was great. He was very knowledgeable. Everyone was very friendly and helpful.

We just bought a high mileage TESLA from star motors. The entire experience and the car itself was great. Alex can actions as very reliable, open and ready to help always. Payment and shipping were managed in a very honest and trustworthy manner.

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

I purchased a 96 Caprice from this dealer.....buying experience was top notch. They answered all of my many questions about the car, negotiated price with me and had the car delivered in record time. The vehicle arrived in an enclosed trailer, was clean and ran perfectly. There were no issues with the car that I found. Normal wear and tear for a 21 year old car but very clean and taken care of. All systems worked as advertised. Top notch vehicle and dealership

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

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.

It was my first time at this dealership and will return for future repairs.The service representative kept me informed which made the process smooth and quick, with clear explanation.

Great place to buy a vehicle. The staff is very friendly and the process was very easy

Got my car serviced here. Honestly I thought I was in for a lot of money on my Panamera but they replaced the engine for a great price …couldn’t be happier. Ask for Carlos

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

My service advisor, Michael, did a great job of communicating the progress of my service appointment. Not all the necessary parts were in stock after the diagnosis, but he kept me apprised of the status of their arrival and made sure I had a loaner when they came in. The technicians did a great job and returned my vehicle in great condition.

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!

Bought a Tesla Model 3, clean car. Well taken care of. Process was very quick and efficient!!!! They sell nice cars at great prices! Will be back for my kids car soon!!

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!

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.

2006 Duramax is great truck for pulling my travel trailer. When just the truck over 20 mpg and 13 pulling a 8,000 trailer. Very comfortable and stable on the road, plenty of power. I installed a Pioneer system with 7" screen, blue tooth, dvd, satellite radio and android auto. With that I have every option of a new truck except the collision avoidance and lane change type items. Great performance!

2017 gmc sierra 1500 bought this truck from them and I’m very happy with the condition

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!!
