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.

Brian and Ayden made my buying experience seamless and enjoyable. They were both professional, knowledgeable, and attentive from start to finish. I appreciated how they took the time to explain everything clearly and made the entire process stress-free. I highly recommend this dealership ? ask for Brian and Ayden!
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.

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!

The proficiency, expertise and professionalism of Euro
The proficiency, expertise and professionalism of Euro Motorcars Bethesda is second to none. My review would be meaningless if I didn’t give very special acclaim to the key associate who contributed great to my extraordinary experience. BRADY INFIELD is one of your greatest assets. He exhibits the professionalism, courtesy, patience, energy, enthusiasm , character, empathy, intellectual curiosity, self control, and self esteem that any organization would need to to advance their agenda! After all, you sell classy cars so you should have class, such as Brady Infield, to embellish your mission. It’s small wonder Brady Infield is a rising star with an enormously bright future; he’s under the tutelage and support of Tyler Griffin. Thank you Tyler Griffin and Brady Infield!

I had an awesome experience dealing with Mercedes Benz of Tysons Corner. This was the best car purchase experience I have had. The sales person Trivian Anand is such a great customer advocate. The manager, Pascuale, bent over backwards to accomodate me. The finance manager (Sue Kim) was very transparent. Overall it was pure joy to deal with these guys contrary to most other car buying experiences

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.

Ask for the AMG certified, Mike prati
It was a pleasure to be a customer at Mercedes-Benz of Alexandria. I have worked with and bought from different automobile dealerships over 20 years. I informed my sales manager, Mike Prati, who was AMG certified what I wanted from a car. He was the FIRST auto dealership manager who listened when I told him exactly what I wanted my car. Mr. Prati knew more about Mercedes than I could have read in magazines, Car Werk, Edmunds, YouTube etc. He explained the different variables of each model with and pros and cons. He directed me to the E class 450 sedan for a test drive. I personally could not have found the car without his background and experience. I bought the Mercedes pre-owned and certified. What made the dealership a phenomenal experience was how everyone listened and were respectful. Often, customers are talked to which happened at another dealership I walked out of two weeks prior. The goal: sell you something you don’t want. Not at the Mercedes-Benz of Alexandria. Later, I required work on the car. In lieu of calling the Service department I contacted Mike Prati. Who does that? I did. He immediately sent a tow truck, introduced me to a service assistant and I sat back as arrangements were made for a loaner. Mercedes-Benz of Alexandria was organized, cooperative and I had details regarding my car in less than 24 hours. The general manager, which people never see at dealership, called me. He wanted to be sure all departments were working together and I was satisfied. I actually think this dealership off of Pickett Rd in Alexandria has the finest employees. Great attitude. Thorough. Buying a Mercedes? I recommend Mike Prati to sell you one at MB of Alexandria.

Best shopping experience
I am very happy with the team of people at Mercedes’ Benz Chantilly. Sodik Lawal sales and David Han finance were the absolute best! They worked really hard to get me my dream car not only that but I got to leave with my car on a Sunday (same day). I work a ton so it was hard to figure out when exactly to go to these different dealerships to find the car I wanted and on a Sunday it’s very limited on where you can go. I went to a couple different dealerships but none like this . Sodik Lawal my sales person told me all they had in stock for the model I wanted with the different price points . He explained each feature in the fullest extent. Not only just a test drive and that paper at the car window but he sat with me and really explained the car as I have not been car shopping in seven years so even the push to start is something to get used to. All the features were amazing to say the least future that excites and I thank him for going above and beyond to help me work with the technology. David Han the finance manager is the absolute best he really fought for me making calls to make sure I got the best rate. I am 23 with not that much credit history just good but not excellent credit and other dealerships ( I went to 5 total) were almost doubling my interest when financing with them despite the down payment I was putting down. It wasn’t the best deal nor did I get all the features I get with Mercedes’ . I was not sold on the car but here you can find your perfect match I’m telling you these cars are like driving a cloud ! Mr. Han really explained my options and the next day got me a better deal. They really worked with me to get me a good car that I am absolutely in love with at a really good price brand new. They make the process easy and explain everything itemized which was not the same experience I’ve had at other dealerships . You see what you get , where the extra fees are for, what features you get, and the coverage is amazing. This team was a absolute pleasure to work with . I cannot thank them enough !
