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’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 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.

Buying a 2017 E300 for the right for price
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 .

SLC FINAL EDITION
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!
