Ray Davino is best person at to work with
Ray Davino always is the best ! He recommends warrantees for future use and has great suggestions for the maintenance of my car. I have been with the Smithtown Mercedes dealership for over 10 years and highly recommend everyone here.

I’ve had many Mercedes-Benz models over the years, including AMG’s and the GLS 450 a wheel drive with 23 inch wheels makes this car track like a race car. Out of all the Mercedes-Benz models this is the best one you’ve ever had. The second row seats reclining just like the front row seats privacy shades and the third row comes in handy when needed plenty of cargo space for all those trips to the airport to pick up family and friends. It gets great gas mileage then other SUVs and it doesn’t look like a box like it’s competition. I had the dealer put the Mercedes-Benz standup medallion on the hood even though it has a huge Mercedes-Benz insignia on the front. I just like to see the stand up Star medallion from the driver seat guide me down the road..

GREAT SERVICE
Everyone was very quick to help me and I was very pleased. Will come back to purchase my vehicle tomorrow! Very clean facility and restroom!
Great Vehicle
I absolutely love the feel and performance of this suv. The electronics are state of the art. Excellent road performance in rain, snow or wind. My only complaint is the running board- it needs to be at least 1 inch wider. Actually dangerous in snow and ice.

THE BEST IN THE INDUSTRY
Fortunately for me I had the best experience with Mercdes of Smithtown. I own a seamless Gutters company and have purchased 4 Diesal mercedez trucks since 2020. Joe my sales men went above and beyond. The dealership treated me so fairly. We did business by phone and I could not say better things about this location. In fact I will be calling them to buy another truck soon. Keep up the great work, and awesome Customer service.

Amazing Service!
I went to Helms for my birthday to get myself a birthday gift where I was assisted by Maurice Martin who was so pleasant, patient, informative and super helpful. I've actually never had such great customer service in my life. I purchased my dream car, a white C300 4MATIC and I couldn't be any more happier with the service and help that I was given. I couldn't thank Maurice enough, he was such an amazing sales person. I also worked with Reggie when it was time to deal with the financial part of the process and he was very pleasant, helpful and informative as well. Not to mention, the atmosphere was also extremely pleasant and clean. Everyone who worked there that I came across was very nice and welcoming. I advise you to visit Helms Bros in Bayside if you're looking for a new ride. These people are awesome!

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.

Great 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.

The best dealership, the best sales agent (Tommy),
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.
