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

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!

Fantastic experience all around. Magdalena was very knowledgeable about the car I was interested in and was instrumental in guiding me through the process. The entire experience was smooth, friendly and professional. Joseph was a delight to work with in finance and he was patient and knowledgeable in working me through that process. There is a reason I have been coming to Infiniti of Naperville for years, and it is because of their team members. Buying a car is stressful enough, but it truly helps to have partners in the process who understand and appreciate my needs and work hard and collaboratively to meet them. Most importantly, Magda and Joseph are great people and I enjoyed hearing about why they are passionate about what they do. Just a great experience all around.

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?

Good service good attention nice place to visit. I will add just one thing at the service shop, a bilingual employee thanks.

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 purchased a new Honda CRV this past weekend from JP. JP is hands down the best there is. Not only is he knowledge and kind, but also works very hard to make sure you get the car you want and that you don't spend too much wasted time at the dealership. Out of all my times buying a car, this has to be the most positive experience I have had thanks to JP. Would buy another car again from this dealership.

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 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.

Love the new experience. It’s top tier. Blew me away with the customer service!!! I recommend this place.

My sales consultant Travis was excellent he has great customer service and explained everything clearly. He made me feel very comfortable from his hand shake to his smile. He did a great job. Thanks Travis.

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

they were very patient did not push me into anything the service was quick the only thing they talked me into was a extended warranty.. hope I never need it and hope it is as good as they say Enjoy

Went from a Sahara Jeep Wrangler to this beauty & i Don’t regret it one bit. Amazing interior & exterior quality. Very clean & comfortable. I love it.

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.

Very nice team members and clean atmosphere everyone including the sales group were great. Select was lacking

We have a model 3 but we want a more comfortable car with similar performance on gas. This car with all the technology packages are more comfortable than model 3 but as smart in terms of driving assistance.

Excellent communication. Prices very good. Transaction quick and accurate. Excellent customer service. Polite and courteous. Great selection of vehicles, especially Teslas.

This car meets all my needs and it had very low mileage and on top of that my note is very manageable to pay. T

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

One of the very best in the industry. Dan is first class, knowledgeable, fair and honest, things you do not normally associate with car sales. Cody was also exceptional. I literally have purchased hundreds of cars in my life and today I still buy from them from a thousand miles away and have them ship me the car. I am always pleasantly surprised when it arrives because they under promise and over deliver every single time!

Owner of the company reached out to me and take care off all issues even it was after work hours. Good customer service.

I am pleased with me car so far loving it very nice and clean I like the black on black and the leather seats with my sunroof

Nicholas was easy to work with and so friendly! Loved working with him and when we are in the market for our next car we will be back to see him!

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

My experience is good but I’m looking for car is hai price But staff is very good and great response 👍

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.

I just bought a one year old GLE 53 Coupe from michael Moran and had a great experience. He was a real professional, none of the typical car dealer nonsense. Everything was very easy and they delivered the car to me one day later. Very good experience

See Farah at Countryside Mitsubishi with the car you want in mind and she will not stop until she finds it!!

Vehicle is spotless from front to back. Inside is beautiful interior. All upgraded features. Great choice in dealership and make and model vehicle. Definitely recommend
