Used Mercedes-Benz GLC 300 for sale near Westmont, IL under $1,000,000

I just purchased a car from Castle Hyundai of Oak Lawn, and I couldn’t be more grateful for the experience. From start to finish, the team showed true professionalism, care, and integrity—qualities that can be hard to come by in the car-buying world. Now I truly understand what they mean when they say “Drive Happy!” Jim (Sales Manager), Nick (Sales Consultant), Brennan (Internet Representative), and John (Finance Manager) were an absolute pleasure to work with. They went above and beyond to make sure I felt informed, respected, and supported throughout the process. They were transparent, never pushy, and always willing to answer my (many!) questions with patience and honesty. It was clear that they genuinely cared—about the car, the deal, and most importantly, about me as a customer. They didn’t just meet expectations - they exceeded them. The entire process was smooth, respectful, and even enjoyable. These are good people who take pride in doing right by others. Thank you to everyone at Castle Hyundai of Oak Lawn—you didn’t just help me get a great car, you made the whole experience one to remember. You went the extra mile (pun absolutely intended) and because of you, I now Drive Happy!

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.

My experience at Autos of Chicago was truly impressive. The team was professional, patient, and never made me feel rushed or pressured. They walked me through the features of each vehicle and helped me choose one that matched my expectations. The pricing was fair, and the paperwork process was quick and organized. I left feeling confident and happy with my purchase. This dealership is a great choice for anyone looking for quality used cars and excellent customer care.

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......

See Farah at Countryside Mitsubishi with the car you want in mind and she will not stop until she finds it!!

I just bought a one year old GLE 53 Coupe from michael Moran and had a great experience. He was a real professional, none of the typical car dealer nonsense. Everything was very easy and they delivered the car to me one day later. Very good experience

Very pleasant environment, friendly staff, has kids area mini Theater, I think best Lexus dealership in chicago

I'm not new to the Mercedes brand, as this is my 4th. This is, however, my first try at the Mercedes SUV. So far, I'm extremely happy. Favorite feature has to be the camel leather seats...an impressive update from the MB-Tex.

Great selection of cars. I bought my Tesla at Affinity and couldn't be happier. After going to a few different places Affinity had the cleanest and by far the best service. I will be back again when the time comes.

A pleasant driving car. Very dependable. But, in my opinion, not very user friendly. The controls for features like like wipers, lights, and GPS are complex and buried under layers. The GPS took me over a route that was 1 hour longer than normal on a 5 hour trip because GPS had avoid carpool lanes turned on. Had to call MB at an 800 number to find out the feature even existed. Also, I HATE the run flat tires.

As a returning customer to Laurel BMW of Westmont, I am very pleased with my car purchase from my initial test drive to the delivery of our new BMW. Thank you very much for your customer focus, attention to detail and follow-up through our quicker than expected delivery process!

This car excess my expectation it is a dream care. I feel so comfortable in it, it has a lot of space for me. I love the automatic park assistance and touch screen.

I purchased my car three years ago, and every time I return for my service appointments, the staff is incredibly friendly. The entire experience, from making the appointment to receiving my car back, is top-notch. I have my own service advisor, Steve, who is amazing. He explains everything clearly and ensures that I understand my options. Steve excels at his job and at building a positive relationship with me. He also keeps me updated by texting while my car is in service. Additionally, the dealership recently underwent a remodel and looks fabulous. They even have a chef who prepares breakfast or lunch when it’s ordered—how great is that? Cooked to order and it’s FREE! My sales representative, Bill Harris, is honest, knowledgeable, and patient, truly an all-around good guy. He even calls me to remind me of important dates related to my car and my birthday, which is such a nice touch. I'm going to be a customer for life! Great job, everyone!

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.

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

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.

Ryan Paul was outstanding! Smooth purchase buying a Q3! He was so personable and made my experience wonderful. He’s funny too. He knew all the answers to my questions as well. If you are in search of a car, ask for him! He made it a truly great experience for me. Thanks! Sid was great too. and shout out Robert:)

Shout out to Genesis for helping us get our dream car , she was very honest , helpful , charismatic ! Anyone will like to buy a Car from her , and she did every single think to make sure my car was clean and in good condition . Also I love my car very comfortable.

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.

Service was amazing! I would say we were in and out within an hour and a half our advisor explained everything to us. We have no complaints.

Awesome service from Jose!!! Very patient and kind. Explained every detail. All dealerships need a Jose!

I absolutely love this compact SUV! Coming from a Subaru Outback, this is light years above and beyond for same year. A quiet cabin is my top want for buying a car. This cabin is quiet and relaxing inside. I’m tall and there is plenty of room. The seats are incredible! Can’t wait to take it on the roads in winter.

Great experience, quick to set up, check in and out and everything was quoted with pricing. Time was appropriate for the amount of work done

Sam provided me with the best service experience , good prices, explained how things go in my car , I have zero experience with cars, he went out of his way to explain everything for me and made things clear

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.

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.

They are absolutely great. They always take care of my vehicle & make me feel like a valued customer. I always recommend or refer others to Jennings Chevrolet.

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.
