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

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

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.

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

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.

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 has been by far the best car I’ve owned. I use Yokahama Avid Ascend tires and have been able to travel in any weather in this car. I had a tire blow out (after 76k miles) and the car never wavered once!! During an extremely busy year I kept forgetting or not being able to take it in for service and went 40k miles over the oil change, that was 100k mikes ago and it’s still running great!! In addition to the comfort and sporty look, it’s fast, fun and easy to drive. The only downfall being the expense of services and repairs, which is to be expected out of a quality, import car. I’ve been able to do a lot of the work outside of the dealerships and found that Ebay, FCP Euro and Rock Auto have had anything I’ve needed for repairs and services. I would recommend this car hands down to anyone, any time.

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.

Amazing Dealer amazing staff great prices. Amazing financing as well. Nick and Rudy took care of me from the first call

I am still driving this car after 11 years. I spent about $2200 on average per year to fix or replace this thing. Still drives good, far more expensive that I would like it to be.

Excellent experience from start to finish! The staff was friendly, knowledgeable, and made the entire process smooth and stress-free. Highly recommend this dealership for anyone looking for quality service and great deals.

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 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!

This car has been the best and most reliable car I have ever owned. My wife got a new car for her birthday or I would not be selling it now.

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 🫶

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

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 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!

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.

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

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.

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.

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
