Used Mercedes-Benz S-Class for sale near Big Rock, IL under $650,000

went it to look at a car that i saw online, called to check if it was available, the moment i stepped in they made me feel like i was family and took really good care of me. Great customer service, and very friendly

Dollar for dollar this is the best car that money can buy. A 3 year old MB Certified car with around 30,000 miles is the way to go. The price will be about 50% of original MSRP so you save about $50,000. I suggest 4 MATIC and AMG trim package. I 've owned other MB's, high end Jaguars, BMW's, Volvo's, VW's and several American cars, new and used. This is the best.

Great service and quality cars, definitely will come back for my future car as well

Excellent car. I am driving S550 2015 for 6 years with no any mechanical problems, this car is soft driving and luxury finish and look.

3RD CAR PURCHASE!! This is the 3rd vehicle we purchase at this dealership. The cars are amazing and the prices are great!!! The service is amazing. They work side by side with finance company making everything run so smooth and easy. The staff is always super friendly. The inventory does not disappoint. So many great options to choose from. Recommend 110%!!! Would not buy a car anywhere else!!! Thanks CAC!

The Vehicle Handel like a dream at any speed the faster the better it handled. The fit and finish is 2nd to none. Great car

Adam & Luis at Genesis of Aurora have provided phenomenal customer service for me & my family since I purchased my GV80. Love my SUV & the way that they take care of our car needs. James D. Orland Park IL

Car is very reliable and have driven it on long trips. in the last few years mostly local driving. Its and expensive car and you really purchase It for its contort and safety. Service has been pretty good i have owned six Mercedes over the years

Really outstanding service. Made transactions very easy and fast. People working there super friendly and courteous.

This car is something I really love. It has so many built in features that are there to assist the driver and passengers, and provide comfort. It is also an impressively FAST car! I was out on an open highway years ago, and the more I stepped on the gas pedal, the faster the car "flew". It refused to level off at any maximum speed.

Was a great visit. All as planned. Fast, communication from Dean was great. Could not be happier with the warranty repair and the smooth process to get it completed.

I have driven an S Class Mercedes since 1995. I have not owned anything else. This 2023 S 580 4matic is amazing. With four wheel steering, turns are tighter than you predict. The performance is more than I can handle today and more than adequate. Interior, comfort and exterior are all within my normal Mercedes expectations. After driving this vehicle for 30 years, I am not sure I can accept LESS. Most any vehicle is accepting LESS. I also own a 2020 Range Rover Sport supercharged V8. Just as impressive but not as comfortable. The S Class is what all other vehicle manufacturers are typically chasing to "meet". I have test driven many comparable cars, but none worth buying.

60,000 miles and 9 years now having some issues. Front differential leak, driver active multi contour seat repair, coolant return hose small leak not major. I’ve test driven a number of other luxury flagships and still find the W-221 S Class to be more comfortable and road worthy. Local independent shop provides excellent service at a significant savings from MB dealership. Still love this car and do not regret purchasing even tho repair and maintenance costs are high!

Excellent customer service!! They help me find the perfect car for me, and kept me within my budget!! Friendly staff and beautiful showroom!! Two thumbs way up!! A shout out to Mike Medina the GM who really helped make this purchase smooth and quick! I will be recommending Elgin Auto Sales to all my friends and family!

MERCEDES MADE AN EXCELLENT CAR DRIVES LIKE A DREAM COMFORT IS EXCELLENT VERY RELIABLE FIT AND FINISH EXCELLENT AND MERCEDES STANDS BEHIND ITS CARS THE DESIGN DONT CHANGE THEY JUST KEEP IMPROVING UPON IT

I have just took delivery of my 4th Subaru. Ed Troike was my salesman for all 4. Ed 's dedication keeps me loyal to the brand. The service department as well as the parts department are extreamly clean, and the employees are extreamly knowledgeable, courtious, and proffessional. I will continue to purchase my vehicles from Ed and recommend this dealership to everyone I can.

This car should be classified as an “exotic”. The S550 Coupe is by far the best vehicle I’ve ever owned. Well, our 2008 S63 AMG was a monster, but very heavy. The ride is harsher than expected over rough roads, but it isn’t close to a deal killer. The interior is perfect, but the controls were clunky at first….until you get used to it.

I recently sold my 2014 Corvette Z51 to Diamond Motorwork, and the experience was outstanding from start to finish. I worked with Luke, who was incredibly kind, patient, and professional. He made the entire process seamless — even going out of his way to meet me at my workplace to pick up the car and finalize paperwork. His flexibility and attention to detail made it easy to choose Diamond over other offers. The price was fair, their reputation solid, and they took the time to ensure I was comfortable with every step. I especially appreciated how Luke worked around my schedule and kept everything stress-free. The owner, Rami, was also very attentive. While Luke handled things so smoothly that Rami didn’t need to step in much, he was present and supportive throughout — especially when I requested a wire transfer instead of a check. That extra layer of reassurance gave me real peace of mind. If buying from Diamond is anything like selling to them, I’ll be stopping in there first when it’s time for my next car. Highly recommend Diamond Motorwork for anyone looking for a trustworthy, respectful, and hassle-free automotive experience.

this has been and still is my dream car ( bought it in 2020) and i am going to keep this beauty forever, the night vision, all glass moon roof, massage seats, hot & cold, park assit, huge back seats, wood steering wheel, air rise or sport mode air bags, i have a hitch and used to pull 2 fast motorcycles like nothing, the power, i have drove it to Mexico about 20 times maybe more, Vegas, LA and never felt ANY kind of discomfort! i bet i can drive to NY and be way more comfy than an airplain! if you are thinking of getting this beautiful car DO NOT HESITATE! you wont want another.

I have owned Mercedes for 30 years.This has been the best dealership of all.Totally perfect

I just picked up my S580 Lux-Line in Emerald Green over Sienna Brown, and I am absolutely thrilled with the purchase. I have owned five S-Class models since 2010, including this new one, and I can say this is the best iteration yet from an overall perspective. While I still think the W222 was the best-looking (especially my 2019 S560 with the refreshed look and AMG pack), this new one does not disappoint at all. The Emerald Green is stunning in the sunlight, my favorite color yet. And the interior is on another level from a luxury and tech standpoint. I loved the interiors of all the S-Class models I've owned, but this current one is my favorite. The seats are super supportive, and the vast amount of tech is amazing. The new infotainment screen takes time to learn and get used to, but I feel the "Hey, Mercedes" function makes doing small things like putting in a Navigation request easier than going through the main screen. From a driving perspective, the ride is the best yet, just like gliding on a cloud. I've been lucky to have driven Bentley's and Rolls-Royce's in my lifetime, and this ride is as close as I've seen the S-Class come to being even with those vehicles on this front. And, the V8 is plenty punchy when needed, so it can be a fun vehicle to take on windy roads if you so desire. Overall, a wonderful vehicle and a bargain when you compare it to the other super-luxury vehicles on sale. I'm looking forward to the next few years of owning such an awesome car.

Had my Mercedes Sprinter RV serviced here. I have used them in the past and it is always a great experience. Mark in service provides great customer service keeping me informed on what is going on during my appointment. They always go above and beyond. Their quotes are on point and I never feel like they are trying to take advantage of me. One of the best dealerships I have ever worked with.

S450 is a great value. Plenty of power. Very comfortable. Quiet and smooth ride. Don't need the big engine. Would definitely buy again. Very dependable.

Yosimar.Navarro was very nice he is Awesome customer service was great help me with understanding everything I needed to know about my new car my service was greatly Appreciated

This would be my second S class I had an E class before and the S class hands-down is the best there is nothing like it extremely classy stylish driving it is super comfortable it’s like floating on air I absolutely love this car extremely Luxury

Great experience in the service department. Efficient and personable! Communication was on point from start to finish.

Professional and Friendly Sales Team: Joe Hegglin and Michelle Mitchell. They were prepared and had the car ready for me when I was on a tight schedule. Additionally, both Michelle and Joe had fantastic follow up.

We recently purchased a 2025 C300 4Matic from Romeoville MB, and the experience was outstanding from start to finish. Jayda and the entire staff were incredibly courteous, knowledgeable, and helpful throughout the process. They made everything smooth and stress-free. Highly recommend Romeoville MB for anyone looking for a Mercedes-Benz vehicle and top-tier customer service!

I just bought my 2017 corvette grand sport two weeks ago. I flew in from New York. I can’t say enough good things about the process. We worked with Armin, he was top notch. He made every aspect about buying this car seamless and easy. He even arranged an Uber to pick me up from the airport to bring me right to the dealership. We just adore our new car. It’s perfect!! A million thanks 🙂 Joe and Denise

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.

Franklin is great. Thank you for your support help and patience with me. Love the car. At rides great. The paperwork and process was fast

Was a pleasure doing business with these guys. Gorgeous showroom with an amazing selection of cars. True enthusiasts here. Got a great price on my car, they offered a fair price on my trade. Were super up front on all details of the car and the deal. Fast and efficient. I look forward to buying again - these guys are more like a fine automotive concierge service than a dealership! Keep it up fellas!

I have owned the car since new. It has been very reliable, extremely comfortable, beautiful and a joy to drive. I strongly recommend it for anyone. I was t-boned by a large pickup truck who ran a red light. The car saved our lives.
