Thank you I much for my birthday present!
Thank you I much for my birthday present! Will was fast and reliable and well informed. The transaction was efficient and easy and the customer service was amazing. My situation was less than desirable and I was blessed with a brand new car with not much to offer! They will make it happen.
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.

Sales and service 6 stars
Have used both service and sales (two new cars). Top tier all around. Honest, fast work at very good prices. No extra work added. Insights shared to prevent problems down the road. Willingness to go the extra mile. No haggle pricing but willing to match any real price. Great finance too. Simple process.
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.

Great experience!
Overall a great experience. Friendly staff, no pressure and smooth purchase. I had my car transferred from another CarMax dealer with no problem and they actually transferred two that I was interested in. This was great, as I was torn between the two and was able to test drive both and make a decision. Very happy overall!

Mercedes Benz Bethesda
I brought my new Mercedes from Euro Motorcars Bethesda. Edwin Escarraman is the best sales representative over there. Edwin gave me the best deal which no other dealership could have given. I'm very much pleased with his quality of service. You will not find a better sales representative at any Mercedes Benz dealer. I highly recommend him to anyone.

Ted Shepherd at Germantown EuroMotors
Ted Shepherd is the kind of salesperson every car buyer hopes to find. He listens patiently and answers questions with honesty and integrity. It was a pleasure to work with Ted. He did not ask me to write this review. I was motivated by my appreciation for the experience.

Finally! Someone wants to sell a car!
I have been in the market to replace my ML400 and was looking to upgrade to a GLE AMG53. I have done my homework and know what I want and quickly learned that I would have to order. I dealt with a number of dealers and sales people (including someone else at this dealership) in my attempts to buy a car, but they either: were non-responsive, wanted to sell me something I don't want, evaded my questions, ghosted me, etc. I love my MB and was hoping to get another one, but it got to the point that I was contemplating switching makes. I finally reached out to Danny Nasr. He was extremely responsive, professional, answered my questions, and provided helpful information. We ironed out my build within a day, and he offered a fair price. I should get my car in in a few months. No games. Done!

The sales team is very knowledgeable and there was no pressure to purchase immediately. Aaron answered all my questions about the vehicle as well as giving me a rather fair price for my trade which actually surprised me. I didn't purchase a vehicle that day, but I will be back for a used AMG.

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!

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.
