Used Mercedes-Benz GLC 300 for sale near Potomac, MD under $30,000

I can’t recommend this dealership enough. Trivan and the rest of his team were a pleasure to deal with from start to finish. I was treated with honesty and respect and therefore they earned my business now and in the future. Thank you for a wonderful buying experience.

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.

My experience was good. However, because the used car was not a Volkswagen, the salesperson did not know a lot of details about the Audi I purchased.

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.

In October 2020 I purchased my 2020 Ford Explorer ST at Koons Sterling Ford and have loved every minute of driving it. I've had it in for regular maintenance and recalls at the dealership but just recently on September 26, 2025, I had my best experience when I brought my Explorer in for a new battery. I had the pleasure of having Bradley Cadenas as my service rep and was very impressed with his professionalism and his outstanding product knowledge regarding my Ford Explorer. I wasn't aware of the FordPass reward points I had accumulated, and Bradley was very helpful in helping me manage these and applying them towards the cost of the new battery and related service work. I felt like I got the "red carpet" treatment and look forward to working with Bradley in the future--he is a credit to the dealership and particularly to the service department. Keep up the good work!

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 sold my car to Jim Coleman Toyota, and I had a fantastic experience! Salesperson Jonathan Wear was very professional and efficient throughout the whole process. He helped and assisted me in the sale while showing flexibility with the terms of our contract, speeding up the payment to accommodate my needs. Jonathan went the extra mile by bringing me the check in person the same day. Thank you, Jonathan, for making my sale such a pleasant experience and for your attentiveness to my special needs. I would definitely go back to Jim Coleman Toyota!

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.

Brian Deckert is the best person to close a deal with, he made everything clear and was very helpful and made it easy to close a deal. Great person overall and would deal with in the future

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.

I will highly recommend this Bill Page Honda who is looking for new and use car. Specially the Sales Consultant name Joe Brennan he is very knowledgeable in his profession. If you drop by to buy your new or use car ask for Joe Brennan he is an excellent Sales Consultant.

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’m a really tough customer and Koons Kiadidna great job! The process was really simple. Jordan, my salesperson, was great and eliminated all of the negotiating and unnecessary stuff usually associated with purchasing a car. Took less than an hour once I got to the dealership. Thanks JORDAN!

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!

Outstanding customer service by care advisor Mr. Leon, he is very knowledgeable, efficient and pleasant to deal with. It has been great experience for car service. Thank you so much. Usama Abdelghany

This car met all my needs. Very reliable and comfortable car. It has excellent quality and interior design. I drive my kids around the town safely.

Was a very efficient process, everyone seemed nice and I felt I didn't have much to worry about. Had a concern with vehicle's battery - they replaced it and allowed me to get it inspected at their Honda dealership, just to make sure everything was in place. 2 months in so far and no car troubles - I'd recommend this dealership to anyone in the area.

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.

This was hands down the best car-buying experience I’ve had in all my years. I’ve purchased vehicles from Mercedes, BMW, Acura, Jeep — you name it — and none of them came close to the level of professionalism, honesty, and hospitality I received at Koons GMC in Vienna, VA. The deal they offered was so incredible that I traveled all the way from New Jersey by Amtrak to Virginia. I’ll admit, I was skeptical at first because many dealerships pull bait-and-switch tactics. But not here. Saleam (Sales), Sait (Sales Manager), and Isabella (Finance) all confirmed the deal ahead of time and honored exactly what was promised. When I arrived just after opening at 9 AM, Sales was still in a meeting, but I was greeted respectfully right at the door. Saleam was paged, and the process began immediately. She welcomed me warmly, gave me a brief tour of the dealership—including the much-needed coffee lounge—and handled all the paperwork, insurance details, and my Costco rebate flawlessly. Sales Manager Sait was exceptional. He thanked me personally for my business — something I’ve never experienced from a sales manager at any dealership in the past. He even told me to call him anytime if I had questions or concerns. That level of care is rare. My experience was elevated even further by Finance Manager Isabella. Her energy was absolutely to the moon. She helped close the best deal I could find anywhere in the NY/NJ/CT tri-state area and the entire DMV region. She offered an unbeatable protection package at a discount, covering dents and mileage, and explained everything clearly and thoroughly. She also respected my time, wrapping up the paperwork quickly since she knew I had a four-hour trip back home. I cannot recommend this dealership enough. If you’re reading this review, do yourself a favor and consider Koons GMC in Vienna. I would happily send any of my friends, family, or colleagues here. They’ve earned a lifelong customer.

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

Came in, was greeted and salesman was knowledgeable and answered all my question. They even matched another quote for my trade in. 2nd VW sitting in driveway from dealership.

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!!!

After a car accident I was not prepared to buy a new car and it was a stressful experience. However ,I highly recommend Chantilly Audi. It was the first place I went after a friend recommended that location. I wasn't sure About buying the car I saw so I checked out Arlington, Tyson's Corner, and Maryland's dealerships. Maryland was too much of a drive than a hassle to go back to. Tyson's corner was really nice But they didn't have what I was looking for. Arlington had another car I was interested in but I would. My gut feeling about Arlington was not good, the reviews about Arlington are not great and my experience ended up being awful. Not recommended At Chantilly Audi , I also highly recommend Kathy for sales, Who was extremely supportive and knowledgeable. 5 Stars for Kathy!!!! I am so excited about my car!

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 service advisor James and whole service staff on time and great team service effort for customer needs.

Friendly staff that was professional and easy to work with. Nice car selection options beyond just Hondas.

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 had a great experience buying a car from Bilal, he helped me out a lot, I'd buy my next car from him, I recommend coming to him.

I have the GLC43 AMG and it's awsome! It has plenty of guts and is extremely comfortable. I would highly recommend this vehicle to anyone.

Hands down, the best dealership in the United States! From the moment I walked through the doors, I knew I was in a place that truly values its customers. The level of professionalism, warmth, and genuine care displayed by the staff is unmatched. This isn't just a dealership, it's an experience. What sets this team apart is its extraordinary customer service. Every interaction feels personal, as if you're reconnecting with old friends rather than meeting someone for the first time. Several team members made me feel like they'd known me for years, remembering small details and going out of their way to ensure I felt comfortable and valued. The staff is not only knowledgeable and efficient, but also incredibly kind and approachable. Whether you're buying your first car or returning for service, they treat you with the same level of respect and enthusiasm. It's clear that this team is passionate about what they do—and it shows in every handshake, every smile, and every follow-up call. To say they have an excellent team would be an understatement. They’ve built a culture of excellence that radiates through every department. If you're looking for a dealership that combines top-tier service, heartfelt hospitality, and a commitment to excellence, look no further. This is the gold standard.

I have had this vehicle for only one month so have not developed much experience with it. I did take it on a 1400 mile trip two days after purchase. It ran well, was very comfortable to drive, made for a very easy trip, was great on gas mileage, and it is very quiet inside the cabin. Seat comfort is exceptional and this, being our first experience with heated seats and steering wheel, was most enjoyable.

Certainly! Here's a review you can use for your experience at Auto Group of Manassas, Virginia: --- ⭐️⭐️⭐️⭐️⭐️ I recently purchased a used car from Auto Group of Manassas, and I couldn't be happier with my experience! From the moment I walked in, the staff was incredibly welcoming and attentive. They took the time to understand what I was looking for and guided me through their extensive inventory with patience. The sales person (Dena) was knowledgeable and transparent about each vehicle's condition and history, which made me feel confident in my purchase. I never felt pressured to make a decision, and they were more than willing to answer all of my questions. When I finally decided on the perfect car, the paperwork was handled efficiently, allowing me to drive away with my vehicle in no time. I also received a walkthrough of the car's features, which was incredibly helpful. Overall, my experience at Auto Group of Manassas was top-notch! I highly recommend them to anyone in the market for a used car. Their commitment to customer satisfaction truly sets them apart.

This car has everything technology offers in it plus more. The feel of this vehicle is extremely smooth snd quiet. One of the best purchases of ever made. I’m extremely pleased and love it

Working with the dealership was great, an easy and stress free process. I highly recommend Koons Woodbridge Hyundai to anyone looking for a great deal on a new lease!

Very happy with purchase. Purchased on-line and car was exactly as described. Dealer arranged quick delivery. I would purchase from them again.

Wally and his team was great. The best customer experience I’ve had when buying a car 10/10

My GLC couple is beautiful and sporty. Very fun to drive. Looking forward to learning all the extras it has to offer. A definite luxury
