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.

Just had a great experience with the purchase of a Pre-Owned MB E350 wagon! Carlos Nazario, the salesman, was great at follow up and making sure everything was ready on time and the car was perfect! Bob Lasagne and Thomas Rudaj were also great to work with, professional and honest and made sure everything was right. I highly recommend this dealership, great comfortable showroom, everyone was very friendly and a pleasure to deal with. Lots of searching for cars and found the right one here!

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.

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.

I can not say enough about this wonderful dealership, I have been a Mercedes Benz owner for 25 years! Mercedes-Benz of Huntington has really kept their promise to make all their customers happy. I especially want to say That Steve Varus in sales and Randy in service has made it easy to purchase and accommodating with the service . This is what makes a repeat owner of 25 years , happy to drive such a wonderful vehicle.

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!

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

Leticia did an outstanding job helping us through the entire purchase process! She went the extra 10miles every time to address our questions and concerns with patience and a smile!

Very professional & knowledgable & friendly Honest trustworthy fast service helped me as soon as I walked in had #'s for me I had my vehicle the next day

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..

This is the second car I purchased from this dealer. In March, I purchased a 22' Outlander SEL for my company car. This week I went back and purchased another 22 Outlander SEL for my wife! Travis, our salesman, went above and beyond answering my questions and finding the perfect trim and color for our new car. I was pleasantly surprised at how courteous and professional Ryan was when it came down to locking in a good price and a monthly payment I was comfortable with. This dealer as a whole has been nothing but OUTSTANDING for me and my family. This is my 8th Mitsubishi purchase over a course of 20 years. I've been to my fair share of Mitsu dealers in the past and can honestly attest to their professionalism and outstanding service.

This car met all my needs and more. Love the interior and the way its moves. So comfortable and reliable! Very pleased with this car!

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.

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!

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.

All I can say salesman’s nick is the best I was very very upset but somehow he worked it out for me great communication well spoken etc. and that smile is a winner every time

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.

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.

This is our fourth Mercedes and Steve Verras has been our sales person since the beginning. He has excellent knowledge of the vehicles and an amazing personality. He makes the entire process quick and easy. The entire team at Mercedes Benz of Huntington NY gets an A from me, from Klint Papadelias in in the Service Department, Gregg Weiss in the Finance Department they are all very friendly and very helpful.

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!

Delightful & pleasant experience with Vincent and Ed at Mercedes of Fairfield. No other Mercedes dealership compares to this service organization.

I received an excellent sales experience , the best thus far. Victor Varga was knowledgeable, accommodating, approachable and helpful. Victor went the extra mile to make my experience a memorable one.

Great dealership, not the average dealer experience. Victor Varga was very attentive! Very helpful staff quick response to my request for information on the vehicle. Of all the cars I looked at the one I bought here was in the best condition.Thank you Victor Varga very much.
