New and used 2025 Mercedes-Benz GLC 300 SUVs for sale near Big Rock, IL

Christian and Rob were the absolute best to work with at Walter’s Mercedes Riverside. They are very professional, honest and straightforward. So happy with our new purchase and the entire process.

Owned for 2 months, replaced a 2023 Buick Envision Avenir. Much better car, more comfortable, more luxurious. Used to Drive Lincolns, stopped as they are now made in China. Compared to Jaguar and Cadillac, clearly better car.

Excellent they care about their customers and are very very professional. This is the third vehicle I have bought from them. I?d highly recommend them to anyone.

AutoNation proved to be consummate professions, living up to the recommendation to go there. They know their business and have amazing inventory. I would recommend them.

I recently worked with [ Jeff ] to get my car, and the experience couldn’t have been better! They were professional, kind, and made the entire process smooth and stress-free. Highly recommend if you’re looking for someone who truly cares and goes the extra mile! 🙌🚗💫

Wanted more information on the damage to a car and none was giving to me

My husband and I had a very pleasant and smooth process in purchasing a used car that we really love. Joseph Ngo was quickly responsive to all of my communications in setting up a time that worked for us all to do a test drive and ultimately purchase the vehicle. The finance officer was also warm and capable and everything was a positive experience.

Gary Fuller was amazing. My husband found a vehicle online. Talked with Gary. Came into the dealership and had the car ready and waiting for us! No pushy sales or playing with numbers. Straight and to the point! Gave us everything we were looking for and even took in our Trade in at Kelly Blue book Value! Loved the goodie bag of merchandise. And the car run down was quick and to the point! Absolutely best car experience I have had in the past 2 decades!

Wonderful experience. I did a fly-n-drive. Bought the car sight unseen and everything came together without a problem. The staff was helpful and efficient.

We had an excellent experience with Norman. He was a pleasure to work with and he was personable, professional, and knowledgeable. We told him we were just looking and he did not apply the usual car salesman pressure but answered all our questions. When we decided on the car we wanted, Norman went out of his way to find it for us. We left very happy.

I was looking at purchasing a 2021 E53 cabriolet remotely. David Olsen was fantastic and spent the time taking pictures and walking the vehicle facetime with me. While considering the purchase, ultimately having to secure my own shipping turned me away from this purchase. The dealer ship is A+++ in my opinion.

First time buying a car from them and I couldn?t be more impressed with how nice the sales people were, I will definitely be purchasing my next car through them,Service was great.

As always, the dealership does top quality work and I am very pleased with the job they did for my 2021 S585 sedan. I was especially impressed by the video of the proposed repairs and maintenance work - a new service that worked out very well. One aspect of this visit however could stand to be improved. It took 2.5 days to return my car to me, largely due to the unavailability of a check out driver to validate that the car was ready to go - at least that's what I was told.

James is a top-notch sales rep. Contacted me quickly and processed my questions and requests efficiently. Will look to work with him in the future! A+

This is the third S-class Mercedes I have purchased from Mercedes-Benz of Westmont and I could not be happier. Going through the purchasing process was a delight because Kimberely Cager, my Sales Rep, and the sales management team made me feel better than just a valued customer. The real test, however, came when driving the new 2025 Mercedes S580. The supreme road handling and comfortable seating were nothing short of spectacular, and the many options like the integrated toll system (driving through tolls of different states has become hassle free), Apple CarPlay, and several driver-assist features has enhanced my driving experience. While understanding how to use and benefit from the many new features and options was a little daunting, Kimberely and the Product Concierge, Damir Oliynyk, have eased my doubts, and I?m looking forward to a long multi-state road trip.

Great experience here as always. I don?t even shop anywhere else. Ernest and Stefan always take care take care of me. Highly recommend a Mercedes Benz of Marietta

It was a great experience from beginning to end. I got exactly what I wanted and it was delivered to me in perfect condition. I can’t thank them enough.

Gianna was amazing! She did a wonderful job helping us find the perfect vehicle for us. I am so excited with my new car!
