Used Mercedes-Benz cars for sale near Westchester, IL

I purchased a car though Guarenteed motor cars this year in March, in which I was looking for my first car. Up until the purchase, I was kindly greeted by Omar, which was my salesman, and he helped me along with buying my car with the interests I had in what I was looking for. After the fact, he offered me refreshments while I was waiting which was very nice of him to do. Because the dealership sells used cars, it’s not perfect condition which I was aware of, but they made sure my car was good with the engine, transmission, etc…, and that the car was clean and ready for me once the deal was done. Any concerns or questions I had, Omar and all of the other salespeople helped me out and made sure that what I was getting into was the best decision. And if I needed any kind of service done, they were going to take care of me, many other dealerships don’t do. Great prices, great cars, great people. Definitely recommend for anybody looking to buy their first car or even trade in their car for an upgrade

I love my GLB but two months and ten days, after the purchase, the engine needed a repair which was covered by the warranty. However, we were planning a lengthy trip and was thankful this did not occur while we were a few thousand miles from home. Me and My Mercedes are still trying to figure our communication out. I prefer Waz or Google Maps to their GPS system. Advance notifications of turns and such are better. Other than these issues I love driving her, Gilby.

I had the absolute pleasure of working with Omar during my recent car purchase, and I can’t recommend him highly enough. From the moment I walked in, Omar was friendly, knowledgeable, and completely focused on finding the right car for me—not just making a sale. He took the time to understand my needs, answered all my questions with patience and clarity, and guided me through every step of the process with honesty and professionalism. What really stood out was how transparent and low-pressure he was, which made the experience stress-free and enjoyable. Thanks to Omar, I drove away in a car I love and with a deal that I felt great about. If you’re looking for someone who genuinely cares about helping you find the right vehicle, Omar is your guy. I’ll definitely be recommending him to friends and family!

A prefect car. So luxurious! Very spacious, great size for family and friends. Very reliable. Would recommend to anyone looking for safety and style at the same time.

Let start off my saying these bugs are great. Made sure I was comfortable with what I was buying and made the process very easy and simple.

I purchased a 2023 Tesla Model S Plaid online from Guaranteed Motor Cars, an out-of-state dealership. The process was incredibly smooth, with outstanding support from their team. They were responsive and made everything effortless, guiding me through each step. Guaranteed Motor Cars arranged free home delivery, and the car arrived in perfect condition at my driveway. Their communication and service were top-notch. Highly recommend Guaranteed Motor Cars for their seamless online buying and delivery experience!

Exceptional customer service and super understanding. No beating and haggling straight to the point. In and out

Without a doubt the most fun luxury car I've owned. Everyone has warned me about how much it costs to fix. I'd like to confirm or dismiss their predictions, but nothing has broken. Other than expensive oil changes and different sized tires that can't be rotated, I haven't done anything but put gas in it.

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

Owning this car, and drives like rocket with F1 turbo tech and 4CYL. Engine difference is just surprising. Love the steering and looking forward to upgrade to 21' rims and apply upgrades.

Owned a W205 C43 AMG coupe and loved it. Wasn’t practical for a family so went to a couple SUV’s. Then this pure F1 tech machine came out and I had to have it! I love the new F1 tech, the handling, standard rear steering, ride quality and interior tech. Definitely recommend!
