Used Mercedes-Benz C-Class for sale near Merrionette Park, IL under $650,000

Entire team was professional and helpful to me during the buying process. Sales Rep was my representative and solely responsible on my same day purchase

Driving this car is so nice it rides so smooth and it has power too. Not to mention it looks really good. Never had a problem with it

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.

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...

Great selection of cars and great prices recommend I bought a 2024 Kia ev9 ask for Joe for the best experience!!!

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.

Great customer service! Joe helped me buy a 2023 Audi RS7 with a great rate!

Truly great car driven it 20k miles over the year, no issues whatsoever (with proper maintenance of course). It gets Great gas mileage, some trips up to 28MPG!

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

I had a great time picking my new car! Matthew Bako was my sales consultant. He was very knowledgeable and professional. It was a very positive experience.

Chris Antzaras at Ultimo Motors has represented my family for 2 car purchases at Ultimo Motors East. He made the purchase of my Corvette Z06 so easy. He is professional, knowledgeable and easy to work with. I understood everything. He’s honest too. I will never purchase from another agent. What a great experience!

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 🫶

I bought my car here and have it serviced here. They are ALWAYS busy, so with the amount of cars who come here everyday, it must be a good sign of how other people appreciate their service. Christine T. Always takes good care of me explaining the necessary work that needs to be done. She talks me through the processes and keeps me updated on the progress of my car.

I have a bit over 100K miles now on my C300, had a few repairs, but overall, a comfortable and fine car for driving around town and travel.

Salesman was very personable and friendly when my wife and I visited the dealership. The finance person was very friendly and very helpful when we needed financing the auto purchased. They both were better than the average dealer staff and I will buy my next auto from this place. The experience there was very easy and pleasant and I will highly recommend this dealership to anyone considering the purchase of there next auto.

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.

Happy that I purchased at this dealership rather than others in town. Turned out to be better deal and better car!

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?

What a convenient way to buy a car! I love the car, it is exactly what I wanted and not being local, it doesn't have the salt rust that cars here have. Extremely smooth process. No pressure, yet very responsive. Much appreciated.

Here it is 2022 and my crazy self just brought a 2010 c class Benz 4 Matc and I am so glad I did performance is awesome love it

Easy in and out nice waiting room kept updating car pr0gress while waiting for car

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 bought a Tacoma from this dealership and I had an amazing experience! Grant as extremely professional!

2013 C350 RWD, AMG Performance and Handling package. 108,000 miles. Bought this car in '16 with 40,000 Miles. It continues to serve me well. The one major problem has been an anti-theft ignition switch that only the dealer can fix. Cost 2k to fix. This is the only repaired I've needed. I have had all scheduled maintenance done, Runs quite well, and still has great performance. Handling is the best.

I recently bought a car at Golf Mil Ford and had an excellent experience with Mike G. He helped us from start to finish and was very helpful in every perspective. I highly recommend Mike.

I cannot say enough about my experience dealing with Diamond Motorworks. My wife and I purchased our first automobile in IL (I'm a transplant) and I cannot say enough about the professionalism, kindness, and thorough handling of our transaction. Rami was a pleasure, answering all of our questions and concerns and wanting us to find the best fit for our needs. I believe in professional service and that is offered in spades at Diamond Motorworks. Our experience was so good that I have recommended 2 friends who have recently moved to IL to seek out Diamond Motorworks for their automobile needs. If you appreciate honest, no hassle and friendly service, this is your place. The vehicles are pristine, the service is top tier, and the transaction seamless. Thanks again Rami and Team!

Barry at Icars of Chicago has been phenomenal since day one, and he truly shines even a year after I bought my car. When I reached out with a follow-up issue, he didn’t hesitate—he jumped in, listened carefully, and helped me get things sorted quickly. It’s rare to find a dealer that stays engaged long after the sale, and Barry embodies that in every interaction. What stands out most is how they stand behind what they sell. I felt supported and respected from the moment I walked in, and that commitment hasn’t faded over time. The team’s customer service is second to none—honest, responsive, and genuinely invested in making sure you’re happy with your purchase. Their focus on building long-term relationships, not just closing a deal, is the best I’ve seen anywhere. If you’re shopping for a car and want a dealership that treats you like family while delivering real value and ongoing support, I’d absolutely recommend Icars of Chicago and Barry in particular. Their customer retention is unmatched, and that peace of mind is priceless.

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.

I had an excellent experience buying a new RDX from this car dealer. Raffy was my salesperson, and he did a great job answering all my questions and explaining everything in detail. I also live in Wisconsin and bought from this car dealer in Illinois and the process was extremely smooth and no extra work on my end was needed. I am very satisfied with the new car and this dealership.

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

Mike Alwin my advisor is the best, Mike always takes the time to go over any of my service needs.

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
