Used Mercedes-Benz C-Class C 300 for sale near Summit, IL

great service, in and out !! I needed them to check out a noise coming from my tire- turned out to be rotor issue- and covered by warranty!!! I'm so happy/!!!

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

The visit to the dealer ship was a nice experience. Mohammmed was my salesman even though I didn't purchase a vehicle. He took time to help me

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...

Bought 4 cars thier in 10 years they our best in sales and service staff the best service is out standing they care alot for customers

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.

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 completed my deal in less then 2 hours , gave me good money for my trade and a deal on the new one.

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?

This dealer had the used car I was looking for. The car had the right mileage and a clean fax. The dealership was 1 hour 20 minutes away from me heavy traffic all the way. I figured I would call and ask about the car anyway but I wasn’t planning to drive there. I talked to Phil, a sales rep, and what a gentleman he was. He told me the car was a trade-in and was in fantastic condition. Well, he talked me into driving down there. I arrived about 10 in the morning and left with my new used car by 1:30 that afternoon. I walked Phil through my 128 point inspection, 2 test drives and I ending up looking under the car for any problems. I could not find anything wrong. The car was in great condition just as Phil had described. Phil was a perfect gentleman through the whole process. Every dealership employee I encountered could not do enough for me. Great experience - great car! 6 star experience!

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.

Just came up from Missouri to purchase my Audi Q5 through text and a few phone calls with Jose my Sales Person. Ty Jose

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.

One of the best thing I ever experienced great customer service highly recommended. Dan and Joe was amazing

Just bought (09/25) a 2010 MB C300 Luxury 4Matic. Car has 46,000 miles on the ODO. Local driving and 700 mile road trip so far. Fun to drive. Very comfortable and looks great. Gas mileage is not for the faint of heart, but it's a Sports Coupe ! So far, love this car.

I had a very positive experience at Autos of Chicago. The team was friendly, knowledgeable, and took the time to understand what I was looking for. The cars were clean, well-priced, and exactly as advertised. The buying process was quick and straightforward, with no hidden fees or surprises. I’m very happy with my purchase and would highly recommend Autos of Chicago to anyone searching for a trustworthy used car dealer.

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

Nora was great! Took the time to help find the right vehicle. She was patient and was great to work with! Mary G.

The confort and luxury speaks for it self. Nice and confortable ride. The car has the speed that I need. I’m in love gain !!!

The whole staff was great and super helpful. Super grateful I was able to get the car of my dreams, the 2024 BMW M3 Competition

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.

Troy and Michelle Ross, my wife and I were looking for a car for oiur son and daughter. We had the wonderful experience of working with Tarique and Wafa not sure if I spelled it correctly but they were awesome taking the time to work with us and having us test drive many vehicle before finding the perfect Subaru Outback . We have had the car for several months now and love it! great features and even better buying experience along with good price made this purchase a good experience!

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 had the pleasure of buying a vehicle with Chris as my salesman. Very quick and easy, explained everything extremely well and even helped me learn the car outside of the dealer. Great guy, great dealer, awesome cars.

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

Had a bit of an issue that occurred right before a planned road trip. Explained the issue and urgency. They picked up the car and returned it the next day. They even filled the windshield wiper fluid to help ensure we had a safe trip. Joe Giuliano ensure everything was seemless.

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!

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.

Awesome car buying experience! My daughter's first car and they made the process quick and easy. Rami and Jacob are the best! From the show room to the car selection... they show class, care, and luxury. Would definitely buy from here again.

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 🫶

When I went to purchase a vehicle, they showed me what they had in the model & color I wanted. They had the largest selection of Lincoln Aviators which is why I went there.

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.

I recently upgraded to a Genesis GV70 and it was an amazing experience. The sales team was patient, kind, and great to work with. I left with exactly what I wanted.

Great to purchase a vehicle that is ready for the road no repairs needed. tires and breaks in good shape. Delivery service available. The financing is painless.

2017 Mercedes c300...This car met all my needs. Great interior and exterior, low mileage. Tires are also in great condition. I will use this car for my everyday use. Great gas mileage.

Yesterday I purchased a car by phone for the first time. As a senior citizen I sold my car on the 9th of March thinking I would get totally travel by taxi or Uber or Lyft but I under estimated the value of getting up and going when you like. The team at CarMax from beginning to directions to the highway were the very best. Each and every member made me feel valued as a customer. And feel like they were treating me like they would their family members. You could not ask for more than that. Bj

I have been the only owner of a 2016 c300 4matic sport for 9 years. I have owned the car since it was brand new in late 2015, and it has had only one issue during the duration of my ownership. The only issue I have had was that leaving it out in the extreme cold seemed to ruin the driver's LCD screen, whereby the screen would show random Chinese, Russian, Korean, and Arabic words before warming up and operating normally. Eventually, the screen quit altogether, but it was very easy to get a replacement. Other than that, it's mechanically extremely reliable, the styling keeps it relevant to today's designs, and the highway driving is impeccable. Performance is pretty mid-tier compared to BMW and Audi, but the engine doesn't have their issues. Overall, it's not a fast car, but it does inspire driving confidence when braking, even if the steering is somewhat lackluster compared to real sports cars. I take very good care of the interior, so there are no peeling issues, no warped wood, and no issues with the plastics, but the rubber seal in the moon roof has been a bit squeaky in certain temperatures, and the dealership said it would cost about $2k+ to take the sliding roof off, replace the rubber seal, and reinstall. The seats have held up very well, the alignment has never truly gone out of alignment, and the gearbox acts as if it's brand new. I do an oil and filter change every 4,000 to 6,000 miles, and I follow the regular dealer-recommended services. Mine just ticked over the 100k mile mark, and I know I'll keep it well taken care of for another 30k to 50k. I highly recommend this car; however, if you're looking for "value," please do not get this car thinking you will be able to afford it when something goes wrong. An average service will run you $250+ every 7k miles, and anything being replaced out of warranty will cost you north of $1,000.
