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

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...

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.

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

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 had a fantastic experience at this dealership! From the moment I contacted the dealership while I was in Tennessee, I flew in, and the staff was incredibly friendly, welcoming, and professional. Uri (The rep) took the time to answer all my questions, made sure I felt comfortable, and went above and beyond to help me find the right car. The entire process was smooth, transparent, and stress-free. It’s refreshing to deal with a team that truly values customer satisfaction. Highly recommend this dealership to anyone looking for great service and an amazing team!

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

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

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

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!

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

The staff was great and Shannon helped make the process simple and easy. Love my new car!

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

Out of all the dealerships I’ve been to, this place literally took out the time to help me find exactly what I needed financially and reliable. Great attitude, amazing energy, and extremely helpful.

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?

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.

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

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!

As a return customer with Mercedes-Benz of Hoffman Estates, I am very satisfied with the customer service throughout the dealership. Worked with David Bennett on my trade-in and his expertise helped me to understand and narrow down my vehicle choice. The entire Team was a pleasure to work with and they got me out the door quickly with my new GLE.

Julio R and Gary K did what was necessary to get my car repaired in a short time with care and respect.

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.

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.

Bought it as certified used with 14,000: miles and 3 years old. Absolutely love the car. Now have 60,00 miles on it. Only cost other than routine maintenance has been tires. One dislike is run flat tires. They make no sense. Also did not like the engine shut down at stops ostensibly to save fuel, but I was able to over ride that. And I bought a spare tire and wheel another major issue for me is you cand buy a trailer hitch for a C 400. You can for other C cars, but not the 400.

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.
