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

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.

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

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!!

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.

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!

I have been purchasing MB automobiles from RVC MB since the 80’s .. I’ve always used the same salesman , Mr Tom Ahrens . Tom has always ensured that my new car purchase goes as smooth as possible .. I’ve always shopped price prior to making the deal - Tom has always beaten the competition prices - a great car coupled with a smooth transaction and a caring salesman working for a reputable dealership works for me !!

Mr ANTHONY ANGELO was the best customer service we have experienced in quite a while. REPRESENTATIVES of this nature should be commended and placed in charge of that department .EXCELLENT CUSTOMER SERVICE!

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 .

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

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.
