2021 GLC300 4matic
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 with Sayed at Sheehy Nissan
I had an excellent experience with Sayed at Sheehy Nissan of Manassas. He was professional, dedicated, and really focused on getting me the best lease deal on my new Nissan Altima SR. Sayed was efficient and made the trade-in process a breeze. Unlike other dealerships where it feels like you're asking for a favor, Sayed worked hard to make sure the deal worked in my favor. His persistence and commitment really set him apart. If you're looking for a new car and want someone who's going to work for you, definitely go see Sayed at Sheehy Nissan of Manassas
Exceptional Comfort
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.

From the moment I stepped into National Motors of Ellicott City, I was met with a friendly, professional environment. Buying a car can be overwhelming, but Johnson made the process easy and not stressfull . The dealership had a wide selection, and everything was clean and organized, which set a great tone right away. I ended up buying my car at a great price. 2.

Great experience, surprised with customer service
I am buying a used car after 8 years, and this was great experience. No haggle is what I care. I was not forced to buy GAP insurance or anything else. The only complaint is, the lady taking down payment at the cashier was hesitant to tell me the details of the transactions before making a payment and showing attitude, but everyone else was great. I highly recommend this carmax.

Great experiences only!
I've had only great experiences at Mercedes-Benz of Alexandria. I bought a used 2012 GLK from Michael Prati, who was able to find me the perfect match within my price range. He talked me through every step of the way and was always transparent and reasonable. Every time I've returned the service has been helpful and pleasurable! Michael gets back to me with any question I have and is always willing to assist me. Highly recommend.

Awesome car buying experience!
Mr. Wright (salesman) and Ms. Hana (financing), provided awesome customer service. They were NOT pushy or unhelpful. Ms. Hana looked at the apr my bank was charging me, and provided me a MUCH lower apr. They made me feel like a valued customer.

Elaina our salesperson was wonderful.
Elaina our salesperson was wonderful. Responded quickly to all of our phone calls with questions. Organized and completed all the documents so when we drove from MA to MD most of the paperwork was done . The car was exactly as described and ready for us to take home after we signed the documents. Dorit in the finance department was also pleasant to work with. Overall, a great experience with pleasant helpful people guiding us along the way. We love the car and recommend Mercedes Benz of Silver Spring MD. Happy customers!

Pascuale and Sang were nothing short of AMAZING and professional! Pascuale met me at the door upon my first visit at the dealership. His kind and honest spirit allowed me to feel comfortable enough to know, this is the dealership I wanted to use. Pascuale and Sang properly prepared me prior to my arrival to retrieve my custom 2025 GLE350 to ensure zero hiccups. I did not feel pressured at all - just relaxed. My vehicle turned out EXACTLY as ordered! Sang walked me through the basics of how to operate my vehicle and I was also pleasantly surprised with a follow up call the next day from Sang.

Joyful Car Buying Experience
Our experience on June 6, 2022 it was a great one. Robert the sales manager and our sales consultant Murad Qazi. Were absolutely fantastic. The customer service received rivaled and surpassed any that you would receive at any Big brand luxury Dealership. Our purchase was reasonable and at fair market value. All of the cars are in pristine condition, so the search for one vehicle could have you challenged in selecting just one. We purchased a 2020 Mercedes-Benz GLE 350 4 Matic that had just been received and had several inquiries already. The experience with Murad was wonderful, a true salesman who put us at ease with his cheerful and comical personality. To note every person we encountered here was a true professional and made us feel like a long time customer and a friend of the business. We are surely to make our next purchase from here and I recommend anyone to come and enjoy this delightful car buying experience. Thank you, Marcus L. Jones

Bought a new car.
Bought a new car. The car salesperson was awesome. First, I called to check the availability. It was in stock; 1 hour later, it was sold and he called me to let me know. Thats okay because that car was heavily discounted. I contacted him again for a car with higher trim. Over the course of one week, he worked with his manager to get me the best deal. I bought the car the following weekend. The car salesperson showed great patience, treated my family with respect and kindness. The dealership paperwork process was straightforward. No headaches. I finished in 1 hour.

Honest and upfront, but with great customer servic
Brian Chanin did a great job working with me on my purchase. He was upfront with me on the whole process, because my budget was a big concern. We knew the car we wanted, but we were tight on funds. At no point did I feel pressured to make a decision. He just explained where we were during the discussion and make sure both my wife and I understood. Once the deal was in place, he checked in on us with the finance department, and even helped migrate the items from our trade in to our new car. Great experience.
