Used 2020 Mercedes-Benz GLC 300 for sale near Northlake, IL

I want to share the fantastic experience we had while purchasing our new Lexus GX from Lexus of Naperville. The entire staff was extremely helpful throughout the entire process, making it a truly enjoyable experience. A special shoutout to our sales consultant, Dylan, who was incredibly patient and thorough during our introduction to the GX. They took the time to explain all the technical aspects of the vehicle, ensuring we felt confident and well informed about our new purchase. We absolutely love our new Lexus and couldn’t be happier with the service we received.

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.

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'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.

Very professional and helpful. Also, the salesperson was very helpful and accommodating. I'm happy to recommend!

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.

I just got my Tesla at Affinity. Milton was amazing. He knew exactly what I needed. I strongly suggest that you go see him before EV credit is over.

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.

Fast and easy. All staff was pleasant, well spoken and mannered. Made an out of state purchase with a few email and phone calls. Sales person Luke was excellent.

I bought the GLC Coupe with the AMG package and it’s the nicest car I have ever owned. The unique two tone (black and cranberry) interior definitely sets it apart from other cars.

Made me feel like family as soon as I walked in very helpful and accommodating to my needs didn?t feel rushed at all great staff and location overall.

Great work, GREAT people. Ask for Mike S. He did the best. Love my ford fusion. Very nice guy, he cared & took his time. ALL my needs were met. Thank you Oak Lawn Volkswagen! Thank you, Amaya C.

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.

Agnes was beyond amazing!!! She was so personable, helpful, and friendly!!!! We drove almost 3 hours to buy our new Land Rover and we would most definitely return to work with Agnes ANY TIME!!!

Great service and prices. We bought a 2006 Audi A3 and are super satisfied with the vehicle. It was a smaller dealer but very professional!

Brought my car in for regular maintenance and Gary made the whole process really smooth. Everything was well organized, and once the service was done, he went over all the details with me. I was impressed with how easy it all was and would definitely recommend this place.

They gave me a great price on my car. Nice honest people, very satisfactory experience overall. I like their ancient wood sculptures around the facility.

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!
