Used Mercedes-Benz GLS 450 for sale near East Shoreham, NY under $899,990

We were in the very capable hands of Anthony Mastroianni, who expertly guided us through the process of purchasing our car. Anthony was extremely professional, very knowledgeable, thorough, and of course patient. He was very attentive and made every effort to answer all our questions and concerns during this process. Additionally, touring the Huntington facility reassured us that we would be in good hands on all our subsequent service visits. We continue to be most pleased with our recent car purchase and would highly recommend our sales consultant, Anthony Mastroianni, to guide potential buyers through this exciting process. Thank you Anthony!

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 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.

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.

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.

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!

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..

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

Amazing experience! Candece and Shane were exceptional, had a car sooner than expected. After an awful experience (or two) at Smithtown Mercedes, Southampton completely rectified the issue.

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.

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.
