Used Mercedes-Benz GLC 300 for sale near Mount Vernon, VA

As always, the dealership does top quality work and I am very pleased with the job they did for my 2021 S585 sedan. I was especially impressed by the video of the proposed repairs and maintenance work - a new service that worked out very well. One aspect of this visit however could stand to be improved. It took 2.5 days to return my car to me, largely due to the unavailability of a check out driver to validate that the car was ready to go - at least that's what I was told.

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.

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.

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.

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

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.

The absolute best car buying experience here. Sincerely grateful for Jason, Eric, and Art — the three people I had the pleasure of interacting with from beginning to end. Thank you all! So thrilled with my new purchase.

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!

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.

Harris was the consummate professional. From start to finish the professional Acura Ambassador all the way. The most through vehicle accessories explanation to his gentlemanly demeanor. He was easy to work with and explained everything completely. We throughly enjoyed the car buying experience. Thank You Harris! Sincerely, James & Katherine Little 2023 RDX ASPEC

The vehicle is safe and yet fun to drive. All wheeel drive with a very powerful get up and go. And yet good fuel mileage. I would suggest it to anyone

This was my first time at this dealership for service and I must say 5 start service! Tonny Wambugu My Service Advisor was great and very knowledgeable about the service that was due and assisted me with the process. I will definitely recommend this Mercedes dealership to anyone who is looking to get their vehicle serviced!!

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’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!

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.

Excellent service advisor and assistant service manager - James Kim. The service department receives high volumes of customers, but James is always ready to give his customers great service and honest assessments and results. While convenience is also a reason I take my vehicle to Koons, pricing is also competitive and I prefer using OEM parts for my vehicle.

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

The entire staff was so friendly and customer oriented! Huge thank you to Omid, Robert and Bryan for being professional, courteous, understanding, and patient! They all made my car buying experience smooth and painless. I have and will continue to recommend them to my friends and family. Enjoying my Tesla Model 3 so much! Thanks again Select Auto Imports!

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.

I had an excellent experience! The Tysons team go above and beyond to ensure you find the perfect car for you at the right price. Shout out to Mike, Lesley, George, Valerie , Emilio and Sam. Thank you!!!

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.

Great to deal with, responsive, competitive , good communication and customer. While I postponed my decision on purchasing I would circle back when I decide to buy.

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!

Fu� a AutoNation dulles Va, Josu� me atendi� y pudo resolver todas mi inquietudes, hicieron cambios de piezas a mi carro de una manera eficiente.

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.

I just bought a car, and the experience was fantastic! From the moment I walked in, the service was top-notch. The staff was friendly, knowledgeable, and made the whole process smooth and stress-free. They really took the time to answer my questions and made sure I felt confident in my decision. I drove away not only with a great car but also with a big smile. Highly recommend!

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!!!

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.

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

My experience with Rene the salesman was very pleasant and he was patient/professional. Excellent job 👍

very nice place had friendly staff who wasn't overly pushy with the sales pitch.

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!

The team at Carmax Gaithersburg was amazing! So appreciate their patience, attentiveness, and professionalism! Great job!

Sporty and luxurious! Drives like a sports car but feels comfortable at the same time. Great car for the family as well. Tech is great also.

I bought a car a couple years ago, Came back today to purchase another one. Truly a honorable dealership the first car i bought did not give me any issues and I loved the deal I got that’s why I am back today they treated me like family and took very good care of me.

We just bought a new CR-V from Honda of Chantilly, and we highly recommend the dealership and salesmen Will and Dio. They were friendly, knowledgeable, and efficient. They didn't pressure us to decide, but when we did, they moved quickly to get the car ready and the paperwork completed. We were also impressed with Rebecca, the finance manager; Alex, a sales manager; and Jamal, the general manager. All are top-notch professionals. If we need another vehicle, we'll go back to this dealership.
