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 recently visited Ourisman Mazda of Rockville, I was blown away by the customer service, great stuff they wanted to be sure that I got all what I'm looking for in a vehicle. Andre (excellent salesman) explained everything about the CX-5 I purchased exceeded my expectations in all terms of quality and safety...
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.

What a pleasant experience.
What a pleasant experience. My first time financing a vehicle. When going to initially look at the vehicle, I discovered a few issues. Obviously no used car is going to be perfect, nor was I expecting it to be. They told me to come back the next day and the issues would be fixed. I came back and they did in fact fix the car. They are willing to and have went above and beyond.

I had the pleasure of working with salesman Kamau Dawson. He was very easy to work with and got me through the process easily and quickly. I almost gave up looking for a car. I had a great experience and I will refer my family and friends to Mr. Dawson if they decide to purchase a vehicle. I was completely impressed with his professionalism and customer service. He was also respectful and not pushy.

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.

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.
