Used Mercedes-Benz C-Class for sale near Lockport, 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.

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.

Scott Woolsey did a wonderful job of guiding me through the process of purchasing the car. He made sure that any questions I might have were answered. Would certainly want to work with Scott on any future purchase.

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.

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

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...

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 people to work with. Very professional, courteous, helpful and thorough. They follow through with all of their commitments. The trade process was straight forward and was just as agreed.

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

We bought a '23 Tahoe Z71 and the sales process couldn't have been more seamless. Our salesman, Paul Degrazia, was terrific and made the purchase an enjoyable process, which is pretty rare. We came to terms quickly and we were finished within a couple hours. We love the vehicle and definitely recommend Bill Kay and Paul.

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!

Dan Basic & his team provide an exceptional experience. The Rogue that I purchased is our family’s 5th car from this dealership. Won’t go anywhere else for lease or purchase. Special thank you to Alyssa & Austin for their professionalism & patience.

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.

Very good profesional Menager Kris and all staff very helpful . They stay with me even after the hours and show me all of the cars I wanna see! So definitely I will recommend this dealership to all of my friends. Thank you again.

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!

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.

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 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!

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

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

I bought my first car from Carbox BMW X4. Perfect service I recommend you guys to him.

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.

We just bought a high mileage TESLA from star motors. The entire experience and the car itself was great. Alex can actions as very reliable, open and ready to help always. Payment and shipping were managed in a very honest and trustworthy manner.

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

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

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.

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

Great service and easy to work with. In and out quickly and they had a great selection of imports.

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?

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
