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.

Excellent customer service during pandemic
We were selling a vehicle. Staff contacted us to give us a link to provide all info for the car we wanted to sell. They gave us an excellent price. ( as evidenced. By kelly blue book ) When bringing car to dealership in East Haven - staff had gloves and masks on. They came outside for paperwork. They were organized. Social distancing followed. We are very please with our experience.
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.

THE BEST IN THE INDUSTRY
Fortunately for me I had the best experience with Mercdes of Smithtown. I own a seamless Gutters company and have purchased 4 Diesal mercedez trucks since 2020. Joe my sales men went above and beyond. The dealership treated me so fairly. We did business by phone and I could not say better things about this location. In fact I will be calling them to buy another truck soon. Keep up the great work, and awesome Customer service.

Tom Aveni is a pleasure to work with
Tom Aveni is a pleasure to work with. We live in northern VA. He was so responsive to our needs that I took the Acela train and Long Island Rail to get to Huntington, NY and bought a GLC300 from him. Great experience all around. And even after a couple of months he still reaches out to make sure everything is good. He also ordered a part that was hard to find and kept me informed until it was found and shipped. He cares and he follows through.He is now my go to advisor for all our Mercedes needs.
