New and used 2025 Mercedes-Benz GLC 300 4MATIC for sale near Brentwood, NY

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

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

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.

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!!!

Leticia did an outstanding job helping us through the entire purchase process! She went the extra 10miles every time to address our questions and concerns with patience and a smile!

Stanley was really a great help. He showed me features on my vehicle and even went out of his way to help me enroll in auto pay. Great guy!

Stanley was very professional and knowledgeable of all features my car has to offer.! I was offered the opportunity to schedule a same day appointment to have Stanley go over all the features.! Truly a great Penske agent.!

Every one was well informed and helpful. My sales person was Matthew Boer. I felt very comfortable with him. Both due to his knowledge and attitude. A hugely different experience than I had elsewhere. He tried hard and succeeded in getting me the car I wanted. Joseph and Jonathan also deserve a mention. Thanks guys.

PETER FEARON. Ever had that stabbing dread of entering a Car Dealership due to the sudden urge of adrenaline coursing through your veins - your body's way of preparing for the inevitable/unavoidable funky sales tactics, mind games performed by shady Car Salesmen? Well, NOT with Peter Fearson at Helms Bro. I was very fortunate that my brother had introduced me to Peter Fearon who sold him a car three years ago. (If this example of repeat business wasn't enough for you then continue to read on). Upon being introduced to Peter Fearon, all of my nerves seemed to subside, as you can immediately tell, Peter is not one of those "shady" car salesmen. His utmost professional behavior is coupled by the reassurance of his humor, kind, and non-aggressive approach. Peter advised me of ALL the solutions possible to help me get rid of my lease by letting my brother and me make our own decision. He tirelessly worked on making sure the numbers made me HAPPY. I honestly felt that he was looking out for my best interest and that's all that really matters - an act of Altruism that is easy by definition, but difficult to execute. I really hope that you choose Peter Fearon to help guide you in your next choice of vehicle. You wont regret it.
