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.
Very happy with my purchase from RBM Alpharetta.
Very happy with my purchase from RBM Alpharetta. The car has a very comfortable interior with all the features available. Handles well in town and on long drives. Good acceleration for such a big vehicle. Love the contemporary exterior.

Again, I had the great experience of dealing with my sales Representative Paul DeMicco,and PeterLanglois I Finance, it was like family, Paul searched all states for the car i wanted, and found it in Tennessee, and had it shipped to Smithtown, how many Sales Representative would do that,the car is amazing, and I definitely would recommend them to everyone, if you are looking for a Mercedes Benz,,please go to Mercedes Benz of Smithtown.
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.

I’ve had many Mercedes-Benz models over the years,
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..
