Used Mercedes-Benz GLC 300 for sale near Worth, 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.

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

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......

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

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.

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.

I had my Outlander serviced at this location and they were able to help us out with great discounts and promotion deals. I am very grateful and highly recommend coming to this location for car services.

Julio R and Gary K did what was necessary to get my car repaired in a short time with care and respect.

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.

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!

I enjoyed my buying experience at the dealership , sales team was great especially Jack. Vehicle features were great with clean condition , I was able to test drive and make a decision. My trade in value was great

Super impressed and happy with my 2024 BMW M3 Competition I purchased at Baha’s. The car’s beautiful, rate was awesome, and the whole experience was wonderful

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.

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.

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.

We purchased our Range Rover at Mercedes Benz of Naperville. It was a positive experience. Our salesman Serafin, was awesome. He made our buying experience great.

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

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.

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.

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!

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.

Salesman was very personable and friendly when my wife and I visited the dealership. The finance person was very friendly and very helpful when we needed financing the auto purchased. They both were better than the average dealer staff and I will buy my next auto from this place. The experience there was very easy and pleasant and I will highly recommend this dealership to anyone considering the purchase of there next auto.

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

I have bought a lot vehicles in my life but this was one of the best experiences I’ve ever had the entire staff was great

Their manager has been extremely honest and professional and everyone there has worked with me to make this happen. I could not be more thankful.

I had an outstanding experience with BG Motor Cars! From the moment I walked in, the team was welcoming, friendly, and attentive. They have an impressive selection of quality vehicles, and I found exactly what I was looking for at a great price. The staff made the entire buying process seamless, providing detailed information and answering all my questions without any pressure. What stood out most was their transparency and professionalism — I felt confident every step of the way. The car I purchased was in excellent condition, and they took the time to ensure everything was in order before I drove off the lot. If you’re in the market for a used car, I highly recommend BG Motor Cars. They truly go above and beyond to ensure a top-notch customer experience!

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.

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
