Used Mercedes-Benz GLS 450 for sale near Millstone, NJ

I was in the market for a high-end car and in the process went to 3 MB dealers. I not only chose the best one but ended up with the best MB ambassador, Joe Sangiamino. I would definitely say Mr Catena “knows how to pick’em.” Joe is an asset to the dealership. He was most pleasant to work with and I would be hard-pressed to go elsewhere. Great to find someone so honest in his dealings. I would be remiss not to mention Joe Sardina who was most competent in teaching me the ins and outs of my car. A totally positive experience!

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.

Working with both Rob and Danny was a great experience. They worked with me on my trade in and got me into the car my wife and I were hoping for. I look forward to working with them again in the future!

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.

Jack Goldberg is the best and got me the best deal on my new Mercedes! I live in NYC and when I first went to a dealership near my house they didn’t have much inventory and I’m addition didn’t really care much. I called Ray Catena and was able to find the best deal possible with the lowest monthly payment possible. Jack gave me additional 100 miles for free to make up for the travel time. I am so happy with his service and will definitely refer him to friends and colleagues! Also his associate Sean was fantastic as well Showing me all The cool features of the new car! Great job!!!

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.

I thought they did an excellent job. I would highly recommend this dealership. Very helpful

Sometimes everything just clicks - the attitude, the atmosphere, the result. You don’t often find a place where you feel good both as a customer and as a person who knows what they want.

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..

Willing to work with you. Corrected issue post sale with no hassle. I’d buy there again.

Excellent service! They made car buying quick and easy! No pressure sales. They have great cars on the lot!

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.

Anyone there doing his best to satisfy the customer I was definitely recommended anyone to go there for shopping.

Recently my daughter returned her HRV Sport lease from Honda Bridgewater. Once again Kesia Rodriquez was very helpful and worked around my daughter's budget. Kesia was patient and informative. She gave us the time to discuss a new lease option. We decided on a Honda Civic Hatchback 2025. Honda of Bridgewater has never disappointed me from sales management, customer sales and service department. They are always very pleasant and efficient. Call Kesia Rodiquez for your next Honda purchase.

Overall quick friendly well informed more expensive than the past but the vehicle was ready earlier than expected. All personnel were accommodating making sure I was taken care of a satisfied.

I've had a lot of experience with different dealers but MB Princeton was the best. Mr. Paul Lai was very helpful and upfront about everything. I wholeheartedly recommend them for their honesty and trustworthiness.

Top notch place. Very easy to do business with, everyone was friendly and inviting. Looking forward to doing business with them again.

Dealership was incredibly responsive to my inquiry - they were really great to work with. I ended up buying a car elsewhere, but J&S Autohaus was a pleasure to deal with.

Good for Travel and Towing, very convenience for every needs. It has most of latest technologies installed inside the car. Many advanced options require users to read the manual.

Charlie was fabulous throughout the entire process. It was a non-traditional deal and he navigated the entire journey seamlessly!! He is an asset to the dealership.

Very professional, timely, helpful, kind service, I am very pleased with the service and customer treatment, thanks.

I recently had the pleasure of working with Daniel Holden at Benz of Little Silver, and I can’t say enough good things about the experience. From start to finish, Daniel was professional, knowledgeable, and genuinely attentive to my needs. He took the time to explain everything clearly, kept me updated throughout the process, and made sure I felt confident and comfortable with every decision. What stood out most was his dedication to providing top-tier service — not just rushing through the process, but making sure every detail was handled perfectly. It’s rare to find someone who truly combines expertise with such a friendly and approachable manner. If you’re looking for someone who will treat you like a valued client and go above and beyond to ensure your satisfaction, I highly recommend asking for Daniel Holden. He turned what could have been a stressful process into a smooth, enjoyable one.

I had a great experience working with Tom Cola. He was very helpful in explaining everything about the vehicle and all details about the paperwork. It was a very swift completion of work order by him. Very experienced and friendly sales person.
