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 had a great experience with Meadowland of Carmel.
I had a great experience with Meadowland of Carmel. First off, my sales associate Dominick was a thorough professional who was very attentive to my needs. He understood what I was looking for and found the right fit for our business. In the end we got a great vehicle, were treated respectfully and got a deal we are very happy with. I would highly recommend doing business with MEadowland!

Great customer service
Honesty and excellent customer service. Worked hard to attract me back through negotiations which I appreciated. Would definitely buy a car here again.
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.

Just as promised. A great used car deal!
Saw vehicle on the internet on a Sunday. Called and AMY answered. Based on her accurate information she invited us to the lot the same day. We drove 2.5 hours and test drove the Honda CR-Z. AMY made sure all of our questions were answered. The car was an excellent deal for the price offered. The car did need brakes and a light. AMY made sure the repairs were done to perfection. She communicated via text over the next few days. Always answered instantly. The car was ready when they said it was. Everything completed as promised. Paperwork was painless. By Wednesday evening I was home with the car! AMY was a professional, the business did what they said. No Gimmicks, no false promises, no issues!

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.

Excellent purchasing experience at MB of Hunt.
We were in the very capable hands of Anthony Mastroianni, who expertly guided us through the process of purchasing our car. Anthony was extremely professional, very knowledgeable, thorough, and of course patient. He was very attentive and made every effort to answer all our questions and concerns during this process. Additionally, touring the Huntington facility reassured us that we would be in good hands on all our subsequent service visits. We continue to be most pleased with our recent car purchase and would highly recommend our sales consultant, Anthony Mastroianni, to guide potential buyers through this exciting process. Thank you Anthony!

Awesome Dealership!
Awesome Dealership! I had a pleasant experience at Mercedes Benz of White Plains. Ardit Shabi (Sale Representative) was very professional, friendly, polite and extremely knowledgeable. He listened to what I was looking for and helped me find the perfect car. Bob Binett, the CPO manager, was excellent as well. The help from both of of them, made it possible for me to get my dream car. You both made my car buying experience a memorable one. All of the other staff here were nice as well. I love the 2 beautiful key chains you gave me. Thank you for arranging registration for me. Last time with BMW, I have to do it myself. What a wonderful service! This is a great dealership that you can trust. Thank you so much.

Still the greatest
After the dealership was sold to Curry I suspected the quality of service would decline as it was the greatest and could only decline. It remains great. The service department and auto body shop are helpful and knowledgable.
