New and used 2025 Mercedes-Benz GLC 300 SUVs for sale near Cos Cob, CT

My 3rd Mercedes purchase but my first with Gilbert. Gilbert worked very quickly to find a car that met our need and his service was exceptional.

Owned for 2 months, replaced a 2023 Buick Envision Avenir. Much better car, more comfortable, more luxurious. Used to Drive Lincolns, stopped as they are now made in China. Compared to Jaguar and Cadillac, clearly better car.

Jay and his manager Evan were a pleasure to deal with. Highly recommend Greenwich Mercedes. Ty Mark

Has to be the best place to purchase your car hands down. I purchased a G63 2016 all thanks to Steve suydam without a hassle or crazy plans to get. I love my car and I will definitely buy my next Mercedes from here. Thank you

Delightful & pleasant experience with Vincent and Ed at Mercedes of Fairfield. No other Mercedes dealership compares to this service organization.

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!

PJ Uva made my entire car buying experience seamless. He is caring and down to earth. He put me at ease while taking the time to review all of the vehicles options. I also closed out the paperwork with Jessica Pugliese. Both Jessica and PJ were up front and transparent with the pricing and extra service options. I would definitely recommend this dealership.

Peter Langlois is an honest, professional who knows how to help a customer find the car of their dreams. I have been a customer of MB Smithtown since 1988 and in all those years of great experiences I have met no equal to Peter Langlois in Sales. Thanks to Peter reaching out to me I was able to purchase the SLC Final Edition before it disappeared! Peter's assistance and follow ups are right on the money. A car is an important purchase for anyone, but if you love cars, then it's very important. If you love cars, then I would recommend that you request the very best there is: Mercedes-Benz of Smithtown and Peter Langlois. Start a relationship that will last a lifetime of worry-free driving: see Peter Langlois and your expectations will be exceeded in every way!

I dealt with Josh Alexander from Mercedes White Plains to purchase my 2017 Sprinter. He was great to deal with, had a lot of patience and if he didn?t know the answer to any of my questions he went to go and find out for me without hesitation. What more can you ask for. I drove 2 hours from NJ and the trip was well worth it. Thanks Josh!

PJ Uva was a pleasure to work with. He was friendly, educated and made our overall experience a breeze. His follow through and communication was stellar. Many thx, PJ!!!

This is our fourth Mercedes and Steve Verras has been our sales person since the beginning. He has excellent knowledge of the vehicles and an amazing personality.
