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.

Excellent experience.
Buying or leasing a car can be quick & painless! It was for me here. I worked with Tom Knoblock Jr. and Robert. Excellent from start to finish. Thanks guys! I love my new GLB.
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.

Buying my 2025 Honda Civic Hybrid was the best car-buying
Buying my 2025 Honda Civic Hybrid was the best car-buying experience I’ve ever had. My salesperson, Jose Nieves, was absolutely outstanding. As a senior, I needed a lot of guidance to understand all the new features, and Jose was incredibly patient, polite, and thorough in explaining everything to me. He made me feel completely comfortable and never pressured me into making a decision—I truly felt like he had my best interests at heart. I want to sincerely thank Jose Nieves for his exceptional service. I highly recommend him to all my friends and family because I want them to have the same wonderful experience I did. A big thank you as well to the entire staff at Hamilton Honda for making this such a great experience! Sincerely, A Happy Customer Barbara J.

Had a good experience overall but was disappointed to
Had a good experience overall but was disappointed to discover that this dealership added $3000 in extra unnecessary fees onto the price of the vehicle listed. This made the price more in line with other sellers. So, it made the deal less enticing. Nevertheless, I was able to negotiate the removal of $1500 of the $3000 so, I did ultimately purchase the vehicle. The rest of the transaction went well. I very much appreciated working with my salesman Tony. He was very knowledgeable about the vehicle I purchased and was easy to deal with. I would recommend this dealer but would advise customers to look very carefully at their offer sheets before signing on the bottom line.

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!!!!

First-class
Extraordinary experience at Ray Catena of Freehold! Steve Chanis, Sales Manager, did everything he could to make me feel like a valued customer. Appreciate the sincerity and ability to trust him and Anthony Nadino. Dylan also did a very thorough job going over how to use all the features in the car. Overall, very positive experience and absolutely different than the several other Mercedes Benz dealerships I stopped in before making my purchase. Highly recommend this dealership and the team of professionals I had the pleasure of working with.

Super Satisfied Customer Here
Let me start by saying I walked out this dealership with a 2022 330i. I have NEVER had a deal go so smooth and add in the fact I was upside down. Josh and his team were super professional to say the least. People are never this honest when buying cars and I have NOT been paid for this review. HAPPY CUSTOMER HERE!!!!!
