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.

Amazing Experience
Great service and were able to do what they had to and were able to fix future problems in my car. But would recommend to other people for sure
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.

Good service
We dropped in without an appointment and worked with Kent to test drive several cars. He was very knowledgeable and helpful. We appreciated how much he was hustling to serve several customers. We really liked that he didn’t hard sell us and was focused on understanding what we were looking for.

Great service!
This dealership was excellent! Our salesman Dominic was very profession, kind and welcoming. He helped me find a Toyota Highlander for my daughter for a great price. The financial agent Mr. Khan was also very helpful to find us the best interest rate possible. I would recommend this dealership to any of my friends.

I would highly recommend doing business with MEadowland!
