An Absolute Dream
I have owned 6 S Class (SonderKlas) cars in my life and each and every single one has been problem free and a pure joy to own, drive, and admire. The 2021 S580 however.. Well this car is truly something special and not an incremental upgrade! This thing is crazy

I used to drive past this dealer many years ago and back
I used to drive past this dealer many years ago and back when it was the BMW of Princeton dealership. I decided to stop in on the way to work. What a great job they did with the place. Since then I’ve been eyeing a Porsche Macan they have and anticipate going in for a test drive with my wife. She is due for a new car. I love the fact that they don’t push on you and let you breathe unlike many car dealerships I’ve been to. Real nice people. I wouldn’t be surprised if my dear is driving the Porsche home this weekend.
Luxury
Luxury at its best, you can’t get better than that with this price range. S 580 is the way to go, the 8 cylinders are so smooth yet so sporty. This car can be Rolls Royce luxury and lamborghini urus if it wants

I recently purchased my 2024 Mercedes-Benz GLS 450, and
I recently purchased my 2024 Mercedes-Benz GLS 450, and once again, Ahmed Abdeldayem delivered an outstanding car-buying experience. This is the fourth car I’ve purchased from Ahmed, and every interaction has been nothing short of exceptional. Ahmed’s professionalism, transparency, and genuine commitment to customer satisfaction make him a true asset to the dealership. What keeps me coming back to this dealership, however, isn’t just the incredible sales experience—it’s the amazing service department. Chad Kaplan, my service advisor, and Annmarie Albaro, the service department manager, are simply the best in the industry. They consistently go above and beyond to ensure my vehicles are well taken care of, providing prompt, efficient, and top-tier service every single time. If you’re in the market for a Mercedes-Benz, look no further than Ray Catena. Whether it’s working with Ahmed Abdeldayem for your purchase or trusting Chad and Annmarie in the service department, you’ll experience unparalleled professionalism and care. Thank you, Ahmed, Chad, Annmarie, and the entire team, for always making my experience a memorable one!

I really can't thank them enough. I was probably a difficult customer because I test drove so many cars, but they were incredibly patient. They never showed a hint of annoyance or tried to push me into a decision. But stuck with me until we found the perfect fit. I highly recommend visiting these guys.
