Used Mercedes-Benz C-Class for sale near La Grange, 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!

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.

Tony's customer service is excellent. He is very knowledgeable and informative. We highly recommend anyone in the market and will be referring our friends and family to him. We could not have asked for a better experience.

They contacted me immediately and explained their process for vehicle delivery. Unfortunately I couldn’t find a suitable vehicle. Very professional and courteous.

Wendy was my sales person and she was the most sweetest person ever. Gave me a great deal!

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?

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

Elvir and Matt did a great job and I was pleased with the attention, negotiation and the car I got.

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

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!

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!

Paul Shamoun at Honda Service is highly recommended! He is such an expert and has excellent customer service skills.

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 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.

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.

Great experience, quick to set up, check in and out and everything was quoted with pricing. Time was appropriate for the amount of work done

Earnest is a great guy. Very helpful and friendly. So nice he helped me with my first car

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...

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.

The experience was outstanding, the salesman answered all of my questions and made the process of purchasing this vehicle a pleasurable experience.

Shawn & Dave is an amazing car salesman they were very patient with me and help me very nice i give both of them 5stars each

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

Wide selection and no haggle are a plus over other dealerships. I like being able to see how many different makes and models. CarMax is the only place I will shop

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.

Mike R was amazing. He even traveled to Chicago to bring our car to a different locations so we could see it. I would highly recommend this location.

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.

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.

I just purchased a Infiniti QX 60 from Motor Werks in Barrington, IL. This will be my third purchase from this dealership and my second experience with Mark Smith my salesman. Mark Smith and Lorena Mena the sales manager make car purchasing a enjoyable experience. No pressure whatsoever and after negotiating a fair deal I drove home in my new car. You would be extremely hard pressed to find a more reputable and honest dealer. No hidden fees and the whole process was completed in about an hour. If you are looking for a new or used Infinti let Mark help you with your search. Tell Mark that Kevin sent you!

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.

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.
