Used GMC Sierra 2500 trucks for sale near Oswego, IL

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.

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.

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 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.

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

This was a great experience and Mike was awesome to deal with. There was no pressure to buy and he answered all our questions promptly

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!

Great bunch of people . Not high pressure sales . They go above on trying to help you and accommodate . I wish I would have went with them but purchased another vehicle thinking payments would be lower but they turned out the same .

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!

I worked with Rocky and had an amazing experience. This was my first car purchase from a dealership of any sort so I was very nervous, but he was incredibly kind and helpful and explained everything I had questions on. He was very thorough and I felt super satisfied when I walked off the lot with my car. Cannot thank him enough! Same with Matt the financial adviser there, he was also incredibly thorough and kind and explained anything I had questions on! I highly recommend this dealership and these guys! They were amazing! :D

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.

Mike Lorenzo, Kevin O Boyle D Arct Luke Stiller were the best people I?ve ever dealt with in a car dealership and I bought over 20 cars

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 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.

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

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.

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.

Professional employees, clean environment, and well maintained vehicles. As a returning customer, this dealer has come a long way and always prioritizes customer satisfaction

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!

Cannot say enough nice things about this dealership, truly excellent service in every department.

I recently bought a Ford escape..with the help of Mike Ryan..He was very helpful n kind. I felt right at ease .Mike is a great sales person and he really listens to you and help anyway he can. I would definitely recommend Greenway autos n definitely look up Mike Ryan! He won't steer you wrong!!!

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

Thanks to Woody Buick GMC for another great experience in purchasing a new SUV. We’ve had the pleasure of leasing and purchasing 8 vehicles through Brian Newcomb over the years and he never disappoints! He always finds us just what we are looking for and makes sure we walk away as happy customers. If you are looking for a new vehicle, Woody Buick GMC is it!

What a great buying experience! Chris, Brandi, and Dan made the purchasing experience super easy!!! No pressure, no gimmicks, no swindling…. Just an EASY and relaxing purchase. Way 2 go team!

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.

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.
