**Chef Gregory Adams' Review of Riverdale
**Chef Gregory Adams' Review of Riverdale KIA** ⭐⭐⭐⭐⭐ Dear Riverdale KIA Team, I can’t express enough how grateful I am for the incredible experience I had with Peter at Riverdale KIA, located in the delightful suburbs of Northern New Jersey, a community filled with wonderful families and friends. As a celebrity chef with over two decades on the Food Channel USA, I’ve built my career on the values of hospitality, professionalism, and integrity. Connecting with millions has taught me the importance of exceptional service, especially in a demanding profession like mine. Recently, I ventured into the world of car buying, which has its own set of challenges. After countless visits to various dealerships, I found a gem in Peter at Riverdale KIA! Even though I live on the Upper East Side in NYC, a single phone call with him convinced me that a 45-mile drive to Riverdale KIA was worth it for my new KIA K5 GT. From the moment I stepped onto the lot, I was welcomed with warm smiles and a genuine sense of belonging. It felt like being among friends! Peter and the team took the time to truly understand my needs, guiding me through a selection of vehicles that perfectly matched my preferences. Peter's extensive knowledge and passion for customer service transformed the entire process into an enjoyable, informative experience. What stood out most was the professionalism and integrity demonstrated by everyone at Riverdale KIA. Their transparency and commitment to customer satisfaction shone through in every interaction. It was clear that building lasting relationships was their priority, rather than just making a sale. Whenever I had questions or concerns, they addressed them patiently and thoroughly. Peter's unwavering dedication to ensuring my happiness made all the difference. He accommodated my schedule and made the paperwork process seamless. It’s evident that the entire organization genuinely cares about their customers. If you’re in the market for a vehicle, I wholeheartedly recommend visiting Riverdale KIA—an award-winning dealership! Be sure to seek out Big Pete; his expertise and friendly demeanor will guarantee you an outstanding car-buying experience. Thank you, Pete, for making this journey so enjoyable and memorable! As a token of my appreciation, I’ll be bringing a Kobe beef ribeye steak for Big Peter to enjoy. After all, it’s all about friendship! P.S. When you visit, keep an eye out for the spilled coffee at his desk! 😁☕️ Warm regards, Chef Gregory Adams
Love my Mercedes
I have been driving Mercedes Benz s class vehicles for over 10 years, traded every 3-4 years and have been very happy, always have them serviced at the dealer, always received a loaner, no complaints.

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.
An Absolute Dream

My interaction with NJ Auto was pleasant and comfortable mainly due to sells rep. Jamal due to his professionalism , knowledge and experience made the buying process effortless. The experience did not stop there, my interaction with manager Felix completing the necessary paperwork to finalize the buying process was also pleasant due to his expertise. I would highly recommend NJ Auto Trackers for anyone seeking to buy a quality high end vehicle

Fantastic!
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!!!
