Wow so impressed amazing customer service. Great cars must visit they go over and beyond to make you happy and satisfied.

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?

Purchased a couple cars from here recently. Great service! Great people! Helped me look at a wide variety of cars to find the perfect one. Overall, great experience!

2012 C250 Coupe summer 2014 CPO purchase. Odometer read 23000 mile as I wrote a check for $2500. Now at 42,000 miles this beautiful Iridium Silver coupe has one repair issue (ESL) It's the best looking car I've ever owned. An 850 mile round trip to AZ - mostly interstate - showed 35 MPG. I rarely push the turbo 4 - - - but when I do - the car responds in a - at least to me - a satisfying manner! In addition to decent highway fuel economy and adequate low end torque the car is just plain gorgeous - inside and out.

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

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.

Always a great experience since we purchased our 2016 gmc terrain. Everyone is always very kind and helpful and knowledgeable. They let us know exactly what we need and get it done in a timely manner.

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...

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.

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

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.

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

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.

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 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.

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

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

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.

Best price for sure. Thank you for easy transaction. Thanks Sam and the hard working team. Minor flaw for a huge saving. Thank you again.

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.

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

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!

Anthony is great! He was very helpful and communicative. He helped explained the service my car would need. I'm very satisfied with the facilities and service!

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 !!!
