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..

Amazing Service And Staff!!
My experience at Mercedes Benz of New Rochelle was nothing short of great. From the selection of certified pre owned vehicles, the staff, the service, everything was excellent. I worked with both Michael Telep and Shawn Martinez who both were extremely professional, informative, friendly and helpful. They helped me find the exact car I have been looking for and even went out of their way to put a nice big red bow on it for my birthday! I highly recommend coming to this location for your next Mercedes and working with both of these gentlemen!

Purchased a certified pre owned vehicle
We had a very positive experience with this dealership. We shopped around and needed a lot of hand holding. The used car manager Joe was great throughout the entire process. We definitely were not easy customers.

Excellent service
Had a slight recall issue that was dealt with fast and professionally. They went the extra mile to accommodate my busy schedule and were super nice! With 3 mercedes I can’t recommend them enough!
Great SUV
My 2 honest cents. Just bought the 2024 GLS 450 and it has a huge presence on road and it looks stunning! I went with the AMG exterior package and it looks way better than the base model. Ride quality is good, very smooth ride on freeways but you do feel small bumps on occasional city roads. The engine is good but I wish it had a bit more power, feels little laggy at low speeds but when you floor it it moves fast and steering is very responsive. On the other hand, cabin very silent tho and you barely get to hear road noise (without acoustic package). The Mileage is incredible on this, wasn't expecting to write about it but the GLS gives better mileage than my GLC. Interiors are amazing and is something no other manufacturer in this segment can match (especially at night with ambient lights), seats are super comfy and the infotainment screens are also crisp. Overall, love this SUV and i'm gonna keep it for a while.

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.

Tom Aveni is a pleasure to work with
Tom Aveni is a pleasure to work with. We live in northern VA. He was so responsive to our needs that I took the Acela train and Long Island Rail to get to Huntington, NY and bought a GLC300 from him. Great experience all around. And even after a couple of months he still reaches out to make sure everything is good. He also ordered a part that was hard to find and kept me informed until it was found and shipped. He cares and he follows through.He is now my go to advisor for all our Mercedes needs.
