Used Mercedes-Benz C-Class C 300 4MATIC for sale near North Aurora, IL

We stopped into Mercedes of Westmont as a second stop in our search for a new car. I am not really a fan of buying new cars, we typically buy a car and drive it until it’s dead, just so we don’t have to go thru the whole purchasing process of getting a new car. Chris at Mercedes of Westmont has completely changed my outlook on buying new cars! He is very professional, but yet relatable and understanding of the process and how to make it a pleasurable experience. We weren’t looking to purchase a car that day, but Chris really listened to our wants and needs and was able to find something for us that fit what we were looking for. He was very patient with us as we made our decision. Hands down the best experience I’ve had buying a car.

Amazing is all I can say. Bought a 2019 Range Rover. Two other dealerships wouldn’t even look at me, but they welcomed me and made me feel comfortable. I will definitely be back when I’m ready for another vehicle.

I love my 300C with the AMG Package. You get a much sportier look and drive. The car rides very comfortably in Comfort Plus but you can put it in Sports Plus and it becomes a whole different car. It feels like the car stiffens up and the Torque is immediately right there. Also, the AMG Package comes with great brakes! At this price point, you're going to hear a slight wind noise at higher speeds and the back seats don't have a lot of legroom. But, as an entry-level Mercedes, this is the best Mercedes for value in my opinion.

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.

Sales rep (Kenn) and GM (Bradley) were awesome to work with. Just the kind of buying experience everyone is looking for. Highly recommended!

While getting groceries out of my car, My trunk came down on my head (C-300, 2017). Sometimes trunk opens after I lock the car. This is dangerous. What is the problem?

i was in and out.. very good experience and i will give my salesman marco torres as much business as i can.. thanks conway imports!

Great driving comfort,loaded with features. Safety is definitely a priority with the MB engineering . I have leased a total of 4 Mercedes and totally satisfied with every single one.

Service was amazing! I would say we were in and out within an hour and a half our advisor explained everything to us. We have no complaints.

Valerie is a pleasure to work with. she?s very helpful and very attentive to our needs. She takes a complete look at our auto needs and never oversells services that we don?t need.

Marco Torrens was excellent and patient the entire time with the process and very polite with every question we asked, the driving test was great and even pointed directions back to the dealership easily

This car met all of my expectations. This car is very reliable. All of the features are great. Love the color. Smooth ride on the road

On August 9th, 2025, a family member requested my assistance in purchasing a car at McGrath Acura dealership in Westmont, Illinois. Our salesperson George provided exceptional support and enthusiasm throughout the process. Although the exact color we desired was not available, George diligently demonstrated alternative options while his manager searched for the desired vehicle. Their joint efforts culminated in a remarkable outcome. After careful consideration and negotiation, we ultimately selected the available alternative. The conversation with George, the manager, and George, our sales representative, was highly enjoyable. Both individuals demonstrated expertise and provided comprehensive answers to our inquiries. They genuinely prioritized our satisfaction. I highly recommend McGrath Acura to anyone seeking an Acura vehicle. Make sure to talk to George in sales!

It’s my 12th Mercedes, this one by far is the best. My salesman Barry Martin always takes great care with me. The C Class technology is unbelievable

Bought a new Tiguan and everything went pretty smoothly. Didn’t have to do a ton of negotiation the sales person was very nice and was knowledgeable about the car. Got some additional perks on the car.

Comfortable vehicle. Gas mileage is good and I use premium. No major issues thus far and anything that has happened like battery was covered under warranty.

Would go there for all my purchase 😁 great service and friendly made be feel right at home as I flew in from Oregon and picked up a truck it was all ready to go and was very Happy

Most reliable and usefull car I've had as a daily driver. Everything in the interior is placed where it should be found functionally. Power, while not a muscle car, is more than adequate. Gas mileage is excellent. Adjusting from Comfort to Sport make a very noticeable impact on the driving experience from gear shifting to steering...

We would like to give a shout out to Hannah Kane on helping us purchase our Mercedes Benz. Hannah was a great sales person. Our purchase was a great experience.

Jerry McDuffie has always been a pleasure to work with. Our family and friends have purchased several cars from him over the last 20 years. He always gives you a fair deal and takes the time to make sure you get the car that is right for you. He is very patient in dealing with us seniors who can be technically challenged about some of the new car features on today's modern cars. I highly recommend Jerry for anyone looking to buy a new or used car.

Let me start with the c300 4MATIC is amazing has enough power to feel it and does good on gas I’ve owned mine since 2020 and have aftermarket parts on it and hasn’t gave me a not one big issue love this car 🫶

This is my second Mercedes-Benz. It’s absolutely the most incredible car I’ve ever owned. I was blessed to be able to custom order this car to have everything I wanted and more inside and out! It literally came straight from Germany to the dealership for me. It drives like a dream. It’s absolutely gorgeous. The technology inside is so amazing! It can drive economically. It can drive more sporty if you want it to. It has so many options and settings for drivers of all kinds. Needless to say, it’s pure luxury inside. You’ll feel incredibly spoiled!

Just purchased a Porsche Cayenne Hybrid, and the experience was fantastic! Simon was knowledgeable, professional, and made the process seamless. The car is a perfect blend of power and efficiency—exceeded my expectations. Highly recommend Simon for anyone looking for a Porsche! 🚘🔋 JD

Absolutely love it, loaded with features including self parking. Sports car with different drive modes and yet luxury comfortable. So far not a single issue, very reliable. Highly recommend.

I love driving this car!! It handles and performs amazing. The interior is beautiful and the sound system is excellent. I get excited every time I drive.

Since moving out to the NW area we have been going to Bigger Chevrolet for service. We only had an issue one time and it was handled immediately by the owner. For me that says a lot so I?ll be a constant customer. When ready to upgrade my vehicle this is where I?ll go because if you have a good service department and the owner responds to any issues, no matter how small then it?s an honest dealership worthy of my patronage. Thank you.

Not enough miles driven to fairly evaluate but look forward to driving when weather is better. I have high expectations! I'll need time to get used to the console controls.

Bought a car for my Daughter, needed radio / GPS integrated system replaced. We took the car and they stood behind the repair of the car. The car is great and my Daughter is extremely happy with her car. I brought the car in for service and they said I didn’t need some of the services I requested which saved me money. They are honest and very nice to deal with.

The confort and luxury speaks for it self. Nice and confortable ride. The car has the speed that I need. I’m in love gain !!!
