Used Mercedes-Benz GLC 300 SUVs for sale near Thornton, IL

Mercedes Benz and honestly it was the most stress free car buying experience I’ve ever had. Kimberly Quintero, in sales, was extremely patient and straight forward. She dealt with me sizing the back seats and taking calls with my wife regarding child car seats and positioning. Kimberly was the absolute best when it came to showing the vehicle and even doing research on work done by the prior owner. It was also a breath of fresh air to deal with someone who was so transparent and not aggressive at all. When it came to signing paperwork Fay Demos shocked me, she was able to beat my credit unions rate. Went in under the impression I was going through my credit union, and nope she beat it. Both Kimberly and Fay went above and beyond and definitely earned my business. I would highly recommend anyone shopping for a Mercedes, or used vehicle, to buy through them.

nice car and no to expensive, comfortable, I can't explain how I like my new Mercedes Benz GLC 300 . My last car was very good , ut my new OMG......

This is the second car I've bought from CarMax (I also once sold a car). Every experience has been fantastic but this actually ranks as the best. Sales Consultant LaShinda John answered every question I had via email and then, for financing, by phone so that I walked in with the exact make, model and trim I wanted waiting for me to test drive and pre-approved for financing. The entire in-dealer experience took less than an hour and a half. Fantastic company and fantastic sales consultant.

Bought this 9/2020. Looked high and low. Found it at a large well known dealership.It was a low milage lease turn in they bought at auction.Excellent vehicle.We have owned Mercedes for 40 years. Always gotten good service from them. An average of 10 years per car. Saved some 2K after reading many "how to buy" on you tube. Rehearse ,rehearse your approach and how to deal with the seller, its worth it. Only drawback is no spare. I bought one and dumped the "run flat" tires- very harsh ride with them.

Extremely friendly and professional people. I would buy from them in the future.

This is our second GLC 300. We love the size and features for our needs (two people). Good mileage 27-29+ around town, 30-32 highway. Smooth ride, easy handling, and I think, nice styling. Newer models have larger screen and are more electronically controlled from the screen. Fields of Orange Park, Fl. has great Service, not cheap, "Mercedes" nuff said, but they will take care of you.

Wonderful experience from first contact through sale. Albert Tulo was knowledgeable, friendly, and efficient with processing my used car sale! Highly recommend!

I traded mine in after 19000 miles for one reason, the run flat tires. they are $300 a piece and last 15000 miles. They might be an option, if you don’t mind putting new and expensive tires on every year but they don’t perform in snow after 5000. They don’t perform great when new to be honest, just better in snow with more tread. I loved the car, but living in hilly, snowy Pennsylvania, it just wasn’t practical. Think twice if you drive in snow or rough roads or just don’t feel like getting new expensive tires every year

This is really a great place, they are so busy it is amazing. Pricing on some cars are fantastic. I just sent a friend there to look at one and it was gone by the time she arrived. I'm sure she'll find another. We bought an SUV, but I am also in the market for a sedan! This will for sure be my Go To place!

Best car I’ve ever owned , very comfortable and smooth ride , great on gas . Also as long you do the proper maintenance the car will last you , had for for 3 years no problems whatsoever. Also very spacious for size. So i definitely recommend this car to family friends or whoever looking for a nice car.

Great service as always. Really liked Francisco. He was very personable and extremely helpful. Very easy to work with. And that's all I have to say.

It’s been a great month of getting to know my new vehicle! I waited 12 weeks from the date of order to pick up my new 2023 GLC, and it was definitely worth the wait! I selected the Exclusive trim, Driver Assistance and AMG Line packages with several add-ons, and I could not be happier. My previous car was a fully loaded 2019 GLC 300, and it was unfortunately totaled in early February on a road trip. My first one was the favorite car I had ever owned and it kept us so safe during our accident, so I knew I wanted a second one. I did not realize I would have to wait so long to get a new one but I am happy I did not settle for anything else. The drive is sporty and smooth, and very quiet. It has a slight hesitation from a full stop. Once you take off it picks up very quickly and sport mode on the freeway is great. The upgraded electronics have been easy for me to understand after I read through the owners manual. One recommendation I have is to turn off the automatic speed change if you are using cruise control and happen to go through a construction zone. The cameras pick up the sign and slows the car down very quickly. I prefer to adjust to those situations manually. The car feels a bit bigger and is so attractive and comfortable. It feels much more luxurious than my 2019 did, and in my opinion the upgrades are worth the price. I absolutely love this car! Happy Shopping!

Jimmy was incredibly helpful throughout my Volkswagen buying experience. He patiently answered all my questions and made sure I felt confident every step of the way. His knowledge about the cars and genuine advice made the process smooth and stress-free. I couldn’t have asked for a better person to guide me—thanks, Jimmy!

I have owned glc300 AMG line for two years and I have positive things to say about it. Only critiques I have of this vehicle are the lack of more screens as there are still analogue speedometers on these year model. Interior could also be of higher quality materials. Rear is good

We stopped into Mercedes of Westmont as a second stop in our search for a new car. I am not really a fan of buying new cars, we typically buy a car and drive it until it’s dead, just so we don’t have to go thru the whole purchasing process of getting a new car. Chris at Mercedes of Westmont has completely changed my outlook on buying new cars! He is very professional, but yet relatable and understanding of the process and how to make it a pleasurable experience. We weren’t looking to purchase a car that day, but Chris really listened to our wants and needs and was able to find something for us that fit what we were looking for. He was very patient with us as we made our decision. Hands down the best experience I’ve had buying a car.

Owned for 2 months, replaced a 2023 Buick Envision Avenir. Much better car, more comfortable, more luxurious. Used to Drive Lincolns, stopped as they are now made in China. Compared to Jaguar and Cadillac, clearly better car.

The customer service was great and very helpful, professional. Please give her a raise or take her out to lunch at the very least.

I have own 2 GLC 300 automobiles as 2017 and this 2019 sportier model AMG upgrades. These are the best cars I have ever owned. Comfort and looks are beautiful. I highly recommend this model.

Everyone there was great especially my Salesman Chris answered all my questions and was willing to work with me without the usual pressure this is my second purchase from them

HAVE. NOT PUT MANY MILES ON HER YET, BUT SO FAR LOVE IT! QUIET, FUN TO DRIVE, A GREAT INTERIOR, LOVE THE WAY ALL OF THE GAUGES AND THE GPS SCREEN ARE ARRANGED. STILL HAVE NOT LEARNED ALL THE CAR HAS TO OFFER, SO MANY BELLS AND WHISTLES!

This is the third S-class Mercedes I have purchased from Mercedes-Benz of Westmont and I could not be happier. Going through the purchasing process was a delight because Kimberely Cager, my Sales Rep, and the sales management team made me feel better than just a valued customer. The real test, however, came when driving the new 2025 Mercedes S580. The supreme road handling and comfortable seating were nothing short of spectacular, and the many options like the integrated toll system (driving through tolls of different states has become hassle free), Apple CarPlay, and several driver-assist features has enhanced my driving experience. While understanding how to use and benefit from the many new features and options was a little daunting, Kimberely and the Product Concierge, Damir Oliynyk, have eased my doubts, and I?m looking forward to a long multi-state road trip.

I didn’t end up buying the car because i didn’t make my decision fast enough. It was sold. But the service was consistent and precise with emails and speedy quick at responding. Loved the service and would definitely recommend this dealer.

On the quality of repair I rated average but I'm very pleased with service but my husband was a little upset on price he said he could of disconnect that bluetooth wire and save me the money but service save me the time. We agree just to get it checked then I decided just to get it done without confirming with him first. Next time I will....Also didn't purchase there. Loved service.

Great inventory, pricing and good service but service is high price for somethings like oil change, other mercedes dealers $100 less for identical service. Walter, salesperson, easy to work with.

Felt welcome as I entered the door. Staff was available and when I asked for the sales person that I had been communicating with, salesperson was waiting.

I am a senior citizen and I want to feel secure while driving, and the SUV gives me that. I am on the short side so getting in and out was a new experience for me, but I learned how to manage it. Once, I found the seat setting the visibility is exceptionally good. It handles nicely on the road with quick pick-up, and the gas mileage is about average.

Great purchasing experience. Very helpful sales personnel and reasonable pricing. Would definitely choose Castle again.

Love the car. 4 cylinder turbo, it has enough oomph to get on the highway quickly, but very comfortable in day to day local commute. AWD excellent in snow. In E mode, engine stops when vehicle does; mileage is very reasonable. Given the grill, black exterior and cranberry-accented seats, it’s a head turner (“Mercedes on steroids” was one comment). Only complaints are have to duck head to get in- and I’m only 5’9”, and the trunk space in less in the coupe model (which also looks sleeker than the square back, so take your pick).

What an awesome experience I had purchasing my car here! The process was simple, quick, and involved none of the typical headache you’ll find elsewhere. The whole crew is great, Clay in particular was beyond helpful and had me leaving happy in my new ride. Thank you guys so much!! 12/10

Good customer service From day one I go over there to buy a car they was good with me they help me a lot even after one week from heaven the car I go back to them the car was shaking need break They help me and fix the brake for me and check the car from A-Z thank you for a good customer service

I love this car. Quiet and just the right size . Super comfortable on long drives. This is my first SUV and I love the visibility as compared to my small Mercedes that I traded in for this. The upgrades and cameras are so improved also. The only thing that could be better is if it was driverless!!!

Worked with long term sales person, Lolita. She was knowledgeable - very responsive to questions, easy to interact with, very familiar with Volvos, and listened to my needs. Had the car I needed been available, we could have worked out a deal.

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.

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!
