Used Mercedes-Benz C-Class C 300 4MATIC for sale near Markham, 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!

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

I contacted them and had a quick response. I was able to test drive the car that night. Everyone there was extremely courteous and able to answer any questions. I ended up buying the car that night. No pressure, no gimmicks, just honest and pleasant. I highly recommend working with these folks, they put the customer first! Thank you, Simon.

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 had a great experience here. I worked with Manny and he did an excellent job. I am very happy with my new car!!!

I’m so grateful for Disa, she was very informative and knowledgeable in helping answer the questions I had regarding a vehicle I was interested in. Thank you so much Disa!

May be too complicated to operate and use available functions . Too soon to tell. I still can not figure out how to set clock to DST!

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.

Great experience buying a preowned vehicle from this dealer. The sales staff were knowledgeable and friendly. They were efficient working through the buying process with us. They also were patient with us as we tested multiple car seats and allowed us ample time with the vehicle as we considered moving forward. Thanks for a great experience.

Very kind and caring . Helped alot to make the deal. Salesman was kept me informed. Lending Maneger also put extra effort to make the deal.

Great follow up, I haven't at this point found unit I was pleased enough to purchase. Thanks for your attention...........done

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.

Kyle is very informative and helpful. He’s also very kind. If you’re looking for a new car be sure to ask for Kyle!!

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.

Good service , service man was kool … easy process . Good vending machines too . Glad I chose this dealership

It was a great experience buying mt car at the dealership. The look and features of the car is what attracted me to it. Donte is a great salesman, he is very knowledgeable. He answered all my questions and show me how to use all the features that the car has.

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

It was a great experience, Will was very nice and well inform as to what was need for my break pads

I had a good experience with Chris Price awesome sales man.. no pushy sales tactics.. he was honest and straight to the point.. I have bad credit.. and was turned down from alot of different dealers Marino, Hawk,Naperville and Shermans.. all said No.. but Carmax have me thre car I wanted wth super low miles.. Thanx Chris you a good guy 🤗

C Class Mercedes are great vehicles. My last one lasted 7 years and 300,000 miles and this one seems even better. Improved interior and exterior styling with many new features. Drives smoothly with power and handles great.

This is a very comfortable car and all the features it offers, ie navigation, audio, etc have easy to use controls. Stylish and luxurious ride at an affordable price. Decent gas mileage to boot.

Everything was great . Andrew was great. I had no problems . All the people I meet were amazing.

I didn’t end up buying the car because i didn’t make my decision fast enough. It was sold. But the service was consistent and precise with emails and speedy quick at responding. Loved the service and would definitely recommend this dealer.

Great inventory, pricing and good service but service is high price for somethings like oil change, other mercedes dealers $100 less for identical service. Walter, salesperson, easy to work with.

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!

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