I absolutely love this compact SUV! Coming from a Subaru Outback, this is light years above and beyond for same year. A quiet cabin is my top want for buying a car. This cabin is quiet and relaxing inside. I’m tall and there is plenty of room. The seats are incredible! Can’t wait to take it on the roads in winter.

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.
Exceptional Comfort
I have had this vehicle for only one month so have not developed much experience with it. I did take it on a 1400 mile trip two days after purchase. It ran well, was very comfortable to drive, made for a very easy trip, was great on gas mileage, and it is very quiet inside the cabin. Seat comfort is exceptional and this, being our first experience with heated seats and steering wheel, was most enjoyable.

Car Service
I would like to take the time to thank Ms Patricia Medina Service Manager at Mercedes Benz in Union NJ. I brought my car in for service June 12, 2023 and a problem occurred. I went to Patricia office to explain my problem and right away she made me feel safe, and comfortable. Patricia was so professional, thoughtful, kind and understanding that after talking to Patricia I felt relieved from the stress that I was experiencing. Right away Patricia took care of the situation. It is a great feeling to know that there are people like Patricia Medina that takes there job serious and care about the people they work with. Thanks again Patricia for your professionalism. You are the best.

Anthony & Ray @ RayCatena great to deal with!!!!
Searching for a convertible for a few months since the wife wanted white with red interior convertible. So, I wanted to take a moment to share my recent experience at Ray Catena, and specifically, my interaction with Anthony Aiello. From the moment we walked into the dealership, Anthony greeted us with such warmth and made us feel like family. His polite and friendly demeanor instantly put us at ease. We had the opportunity to test drive the car and Anthony patiently went over all the features, ensuring that we had a thorough understanding of everything. I must say, it was truly a no-brainer for us to seal the deal with Ray Catena, primarily because of the exceptional service Anthony provided. His knowledge and enthusiasm for the product were infectious, and it was evident that he genuinely cared about our satisfaction. I cannot recommend Anthony and Ray Catena highly enough. If you are in the market for a new car, I urge you to visit their dealership and ask for Anthony. You won't be disappointed! Thank you again for your time, and patience you showed us please. Not the first Mercedes and won't be our last. Thanks Again Ray & Anthony!!!!

Everyone, from Austin the sales person to Jessica the sales assistant to the pre-owned sales manager and finance person, could not have been more friendly, helpful, or accommodating. I have owned and leased probably in excess of 100 cars in my life and this was by far the best experience I've ever had.

Happiness at MB Edison!
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!
