Used Mercedes-Benz GLC 300 for sale near Gaithersburg, MD

★★★★★ Best Car-Buying Experience of My Life – Tony Rincon, Owen Stepp, and James Wang are absolute legends at Lexus of Rockville From the very first inquiry to driving home in our gorgeous 2021 Black Onyx LX 570 with my wife and kids, including our 9-month-old baby, the entire team at Lexus of Rockville made this the smoothest, most transparent, and genuinely enjoyable purchase I’ve ever had — and we’ve bought a lot of vehicles. Tony Rincon is hands-down the best salesperson I’ve ever worked with. Zero pressure, lightning-fast responses even over Thanksgiving week, detailed photos and videos every time I asked, and he treated my family (including the baby) like his own. Tony never “sold” me — he just helped me fall in love with the perfect Lexus. Owen Stepp, the Sales Director, went so far above and beyond it’s almost unbelievable. He personally reworked numbers multiple times (including the day before Thanksgiving), honored every promise, and delivered the strongest trade-in I’ve ever received on my 2024 4Runner — thousands above every published value. Owen’s integrity and willingness to make the deal perfect turned what could have been a negotiation into a true partnership. James Wang in Finance was the perfect closer — completely transparent, no high-pressure add-ons, walked me through every single line item with patience and clarity, and made the paperwork painless while I held the baby. In an industry that can feel stressful, Tony, Owen, James, and the whole Ourisman Lexus of Rockville team turned it into one of the happiest memories we have. As a 100 % disabled veteran with a young family, the respect, kindness, and honesty they showed us meant the world. If you’re anywhere in Maryland (or willing to make the drive), ask for Tony Rincon, Owen Stepp, and James Wang. You will not find a better team or a better experience anywhere. We absolutely love our “new-to-us” LX 570 and we’re already looking forward to our next purchase with these guys. Thank you, Tony, Owen, and James — you have customers for life! Happy Thanksgiving. Francisco, Mrs. Gonzalez, kids & baby Lexington Park, MD

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.

It was a pleasure buying a vehicle from this dealership. The salesman was great and the manager was excellent.

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.

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.

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.

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.

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

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!

Big shout out to the team at Koons Toyota for making me and my mother very happy. They went above and beyond to make sure my mother and I were taken care of. It was worth the 7 hour drive and would recommend these guys to anyone looking for a vehicle. Appreciate all you guys did for us and god bless.

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

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.

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

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!

Everyone at AutoNation Honda was friendly and made sure we left happy with the car we wanted, at reasonable price, with everything taken care of so we can start driving it right away.

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......

I had an excellent experience purchasing my car at Audi Tysons Corner today. The entire process was smooth, transparent, and truly enjoyable. Big thanks to Manni and Michael for their outstanding service — they were professional, knowledgeable, and incredibly helpful from start to finish. I’m very satisfied with my purchase and highly recommend this dealership!

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.

Service was experiential,Professional and knowledgeable Everyone from the front desk attendants, to the service representatives had great customer service support. They answered every question presented to them with accuracy. They also provided solutions if needed.

Zehedur Rahman was a kind and helpful sales associate! Shaikh was great to work with in the finance department! Highly recommend! No pressure treatment. No haggling.

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!!!

I was referred to Mike Zeller from a previous customer of his and he did not disappoint! His friendly nature, his laid back approach and his sense of humor made the whole experience 100% worth it. I wasn’t planning on buying same day, but Mike made it so easy that it was silly to not just proceed. Pricing, explanation of process and demonstration of car and its features was so relaxing and great. Why can’t all dealers be like this! Sheehy Ford of Gaithersburg is very very lucky to have him. And now, I have a trusted friend in the car business. Thanks Mike Zeller and thank you Sheehy!

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.

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.

I'd been shopping for a 2025 Ridgeline for several months and found exactly the color and trim package I wanted at Sheehy for a good price. Most dealerships hadn't marked down the 2025 models when the 2026 models came out, but Sheehy offered a good price AND gave me an additional military discount. On top of that, the salesman (Jay Santos) was top notch. He came in on his day off to work with me on a Sunday, and was very professional and knowledgable. Often, the car buying experience is tedious and unpleasant. But with Jay is was straight forward and efficient. When it comes time to do this again, I'll be looking at Sheehy first.

Isrsel here i just want to let you know I had such a great experience working with Candice. She kept me informed every step of the way and is very personable and a helpful person.

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.

Scott and the team at BMW Rockville were amazing as always. I came in for new tires, and the entire process was smooth, professional, and efficient. Great service, clear communication, and a consistently excellent experience. Highly recommend!

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.

All staff was 5 Star. Very timely and professional, From start to finish provided amazing service

I have this dealership10/10 the best and kudos to salesman Adrian Noorestani! He was awesome- no plan to buy yet but bc of his diligence to follow up and explain the features of the HRV 2026 I end up buying and Iike how he knows well the car but he is not pushy unlike other salesman. Andrian is so patient and willing to listen to customer! Honda should give this man a raise!!!
