Used Mercedes-Benz GLS 450 SUVs for sale near Commack, NY

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 .

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.

Look at that smile !! Thank You Jerry Sherry for Maureen's 2024 GLC300 ! Amazing customer experience. Ralley Motors are the absolutely best in the industry. We will definitely be back for the next purchase.

I would recommend this dealership to any of my friends. My experience was great with this dealer in purchasing the Mitsubishi outlander. Very professional. Excellent

I bought this vehicle is a retirement car. He moves great is responsive and very smooth. I wanted a retirement car for my retirement. I am 60 years old and I want that something that represent my current status with luxury interiors, beautiful blue color, and 20 inch wheels it is awesome looking. I can reach 70 in the blink of an eye any moves like it's going at 30 or 40 miles an hour. He has an awesome radio system. although it is not all digital, the radios are for listening. I have an excellent sound, System. Great interiors, great materials, great lighting if you're planning to buy a GLS the 450 is definitely one of your best choices.

I would highly recommend working with Ralph Rodriquez at Mercedes-Benz of White Plains. He is very knowledgable about the brand and models but isn't pushy. He made the buying process super simple and valued my time. The dealership has a good selection of certified pre-owned cars at excellent prices.

I had an incredibly smooth and painless new car leasing experience yesterday with Trentino Manco and his colleagues at Rallye Motors in Roslyn. I was not surprised – I have purchased and leased my last four cars with Trent’s assistance. He is always professional, helpful, honest, and trustworthy. Trent has made the previously unpleasant car buying/leasing experience a thoroughly enjoyable one. I wholeheartedly and highly recommend contacting Trentino Manco and his team if you are looking for a new Mercedes. You will be in good hands.

very happy with the service, Matt the service manager as well as Joe the service advisor were very helpful, for a small dealership they do care about the customer

Tiene mucho espacio, perfecta para lo que necesitaba, muy cómoda, segura para mi famlia este modelo es un espectáculo, los asientos muy cómoda, buen motor.

Bought a car. Price higher than perceived. But car seems solid. Rear fog light started acting up after leaving the lot

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

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!

PJ Uva was a pleasure to work with. He was friendly, educated and made our overall experience a breeze. His follow through and communication was stellar. Many thx, PJ!!!

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.

Saw the g class bought the class in less than 3 hours. Alfonso the sales guy was a PRO! He did FaceTime walk around. I've been shopping for weeks and this dealership had it priced right. From NY to Texas. Will let you know about the shipping and final outcome and one last point NO hidden xx fees like doc destination or whatever. This is a first class Merc dealer.

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!

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..

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!

Exceptional vehicle in the SUV class. We drove the BMW X7, Audi Q7, Volvo XC90 and this GLS 450 just kept blowing them out of the water. The ride is amazing and we feel the comfort level and size is the best

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.

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 experience at this dealership was lovely. Maurice Martin was very patient and willing to make me happy. He kept me abreast of the status of my vehicle and the presentation of the car was regal.

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.

The process was efficient and Rich was very thorough, responsive, communicative, knowledgeable, and made the experience of coming to see the car, discuss options for purchasing, and buying the vehicle very easy. 10/10 recommend this dealership.

they made it so easy to get my car it was a pleasure dealing with all people at this dealership i would recommend it to everyone that i know that are looking for great cars

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.

Mercedes of Massapequa makes shopping for a car easy and effortless. Albert helped me through the whole process of buying the car and getting the best deal possible. 100% recommend this dealership and make sure to ask for Albert!

Best customer service and very smooth process. Highly recommend going to Albert Salib. He made the purchase smoothly. I recommend my family and friends to see Albert!!
