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.
The features are amazing,stylish .
Great driving comfort,loaded with features. Safety is definitely a priority with the MB engineering . I have leased a total of 4 Mercedes and totally satisfied with every single one.

I truly needed a quality car bt was on a budget. This is the place! Great customer service! Just ask for Patrick and he'll have you riding in no time. Looking forward to more business soon!!
Most incredible car I’ve ever owned.
This is my second Mercedes-Benz. It’s absolutely the most incredible car I’ve ever owned. I was blessed to be able to custom order this car to have everything I wanted and more inside and out! It literally came straight from Germany to the dealership for me. It drives like a dream. It’s absolutely gorgeous. The technology inside is so amazing! It can drive economically. It can drive more sporty if you want it to. It has so many options and settings for drivers of all kinds. Needless to say, it’s pure luxury inside. You’ll feel incredibly spoiled!

Came in with bad credit and initially wasn’t hopeful on
Came in with bad credit and initially wasn’t hopeful on even leaving with a car but ended up getting a good rate and there was Transparency from the whole team,Didn’t get the names of everyone but got assistance from Hakeem Blake and he was honest and truthful through the whole process and got us a good deal. Would recommend this dealership for sure they were professional and well knowledgeable on the process.
Haven't put many miles on due to snow and ice.
Not enough miles driven to fairly evaluate but look forward to driving when weather is better. I have high expectations! I'll need time to get used to the console controls.

Happy with my new Jeep
Paul was great to work with! My previous car got totaled and I only had a few days to find something new that I liked and was in my price range. The staff there were all so pleasant and helpful. They did whatever they could to make sure that I was happy with the car I chose and got me a monthly payment that worked for me. I love my new Jeep and would recommend them for anyone’s future purchase.

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!!!!

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!!!!!

Happy with both our Mercedes purchases with Mary K
Extremely Happy working with Mary Kodak with both our family cars purchases. Looking forward to purchasing a SUV with Mary as soon as the one we're looking for is available. First purchase was a 2016 E350 and the second was a 2017 S550. Mary made us feel cared for and was extremely efficient. Very happy with Mary
