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.

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.
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.

Pascuale and Sang were nothing short of AMAZING and
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.

As always, the dealership does top quality work and I am
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.

Nick Bernicat (our sales person) was so incredibly
Nick Bernicat (our sales person) was so incredibly patient, understanding, respectful, personable, and professional, and he made our car buying experience so much easier and less stressful than it had been until we met him. He was truly a pleasure to work with. We had been to other car dealerships and had encountered the classic aggressively pushy tactics car salesmen are known for, and Nick was anything but that. He intentionally cut out time for us to talk alone and never made us feel pressure to buy. He helped resolve all of our concerns and was open and honest throughout the entire process. After telling him about our previous experiences, he assured us that he wasn't there to push us and that it was okay if we didn't decide to buy. He said his focus was to build a good relationship with us so that even if the dealership didn't have what we were looking for, we would still be comfortable coming back when we were ready to buy years down the road. We'll be back on the market again in a year or so to get a second car, and if this dealership has the right car for us, we're definitely willing to drive the two hours back to buy from him again. His focus on human connection made working with him enjoyable, which is saying something because we had been dreading going into another dealership. Our financing experience was much more mediocre. It was 8pm by the time we got to the finance guy and he wanted to go home. He was dismissive, and while he would answer direct questions, he didn't have much interest in slowing down to explain anything we asked about. I felt kinda trampled and didn't really enjoy any of the interactions with him, but I'd still go back to work with Nick.

was recommended by family and friends to buy a car from
was recommended by family and friends to buy a car from this dealership, and now I understand why. Due to personal and financial hardships, I wasn’t able to purchase a car right away. Despite that, they generously provided me with a loaner vehicle at no charge, which was a huge relief during a very difficult time. Their kindness and understanding meant the world to me. On top of that, they even made a donation to the Buddy Walk organization. Their compassion and community support truly set them apart. I'm beyond grateful.

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.
