New and used 2026 Mercedes-Benz GLC 300 for sale near West Islip, NY

My Mercedes Experience of RVC is always pleasant, effortless and professional because of my incredible salesman, Craig German. Craig sold us our first Mercedes and we haven't dealt with anyone since that time. Not only is Craig extremely professional, he is knowledgeable about the product he sells. He is just an overall nice guy, who enjoys the public and making sure his customers are satisfied. More people in sales should be like him. We don't want to deal with anyone else! We hope Craig is there whenever we want to do some future business with MB of RVC!!

We just purchased a car from this dealership, and the experience was night and day compared to our prior one at another Mercedes dealer. The team here is incredibly friendly, down-to-earth, and easygoing—such a refreshing change! Albert is the one who helped us, and he truly went above and beyond. He was patient, helpful, and never pushy. He even took the extra steps to help us clean out our old car, remove the old box and items, and made sure everything was taken care of. It was such a smooth and relaxed experience—nothing like the stressful process we had at the other dealership. Highly recommend working with Albert if you’re looking for a great car-buying experience!

I had reached out to several car dealers regarding Mercedes and BMWs and Rodni was the first to respond. Even though I live in Central NJ, his prompt response was impressive so I went out to this dealership a few days later. I wound up purchasing a beautiful Mercedes and I'm very pleased with my dealership experience.

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

MB of Rockville Center is the best dealership. Thomas Ahrens is the best sales agent, ask for Tommy if you are in the market for a Mercedes Benz. The staff is very friendly and professional, I enjoyed my purchasing experience.This was my second Mercedes Benz.

Amazing Team! Albert Salib was great help and very kind. Helpful team all around and great environment in the dealership!

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!

My experience at Mercedes Benz of Rockville Center exceeded my expectations. My salesperson, Jerone Sealy was exceptional, he was friendly , professional and displayed a very calm demeanor in his approach to selling. I never felt pressured. Jerone explained in detail every question I had regarding the vehicle. He was very knowledgeable and provided excellent customer service from the beginning to the end of the sale. If I had to rate him from 1 - 10 he deserves an 11. Jerone Sealy thank you so much. I love my GLE 43 Coupe just as you said I would. You are a top notch salesperson!

Mercedes of Massapequa makes shopping for a car easy and effortless. Albert helped me through the whole process of buying the car and getting the best deal possible. 100% recommend this dealership and make sure to ask for Albert!

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.

TONY MANGIOLINO WAS TERRIFIC HE WAS A TRUE GENTLEMAN--NEGOTIATION PROCESS WAS PAINLESS. DID NOT PURCHASE CAR YET--BUT WILL TURN BACK TO HIM IN NEAR FUTURE FOR PURCHASE

Just had a great experience with the purchase of a Pre-Owned MB E350 wagon! Carlos Nazario, the salesman, was great at follow up and making sure everything was ready on time and the car was perfect! Bob Lasagne and Thomas Rudaj were also great to work with, professional and honest and made sure everything was right. I highly recommend this dealership, great comfortable showroom, everyone was very friendly and a pleasure to deal with. Lots of searching for cars and found the right one here!

It’s probably one of the best luxury car dealership in New York if not in the country, and Victor Cosme our sales consultant made that possible .

Look at that smile !! Thank You Jerry Sherry for Maureen's 2024 GLC300 ! Amazing customer experience. Ralley Motors are the absolutely best in the industry. We will definitely be back for the next purchase.

I had an incredibly smooth and painless new car leasing experience yesterday with Trentino Manco and his colleagues at Rallye Motors in Roslyn. I was not surprised – I have purchased and leased my last four cars with Trent’s assistance. He is always professional, helpful, honest, and trustworthy. Trent has made the previously unpleasant car buying/leasing experience a thoroughly enjoyable one. I wholeheartedly and highly recommend contacting Trentino Manco and his team if you are looking for a new Mercedes. You will be in good hands.
