I recently had the pleasure of working with Daniel Holden
I recently had the pleasure of working with Daniel Holden at Benz of Little Silver, and I can’t say enough good things about the experience. From start to finish, Daniel was professional, knowledgeable, and genuinely attentive to my needs. He took the time to explain everything clearly, kept me updated throughout the process, and made sure I felt confident and comfortable with every decision. What stood out most was his dedication to providing top-tier service — not just rushing through the process, but making sure every detail was handled perfectly. It’s rare to find someone who truly combines expertise with such a friendly and approachable manner. If you’re looking for someone who will treat you like a valued client and go above and beyond to ensure your satisfaction, I highly recommend asking for Daniel Holden. He turned what could have been a stressful process into a smooth, enjoyable one.

A surprisingly pleasant experience
Best experience I've ever had with a dealership service department! Michelle and Jack picked up my car and returned it to me!! Friendly, clean, pleasant and competent. So rare these days. I would recommend them highly, especially over Freehold Buick. Freehold Buick tried to rip me off on several occasions. They lied to me and were disrespectful. I'll never go back to Freehold Buick, but look forward to working with Jim Curley Buick of Keyport in the future. Thanks so much.
Nicest, best performing truck I've ever owned
My truck has a great appearance, inside and out. It is a pleasure to drive; and rides and performs great. It is the best truck I've ever owned.

I purchased a used vehicle on May 10 of 2025.
I purchased a used vehicle on May 10 of 2025. I actually started the purchase on May 1, but it was for my business and took a little bit longer to secure funding, etc. I work with Frank, who was amazing. He was patient, kept me informed, helped me along in the process, and delivered the vehicle so smoothly. Zach, the finance gentleman, was also amazing. The entire process was smooth and easy, and I would absolutely go back.

We recently purchased a 2003 Ford Thunderbird from
We recently purchased a 2003 Ford Thunderbird from Highline Motor Cars. Ali was our salesperson and he was very helpful. After looking around for this particular model, we found exactly what we were looking for. Ali gave us a good deal and was upfront regarding some routine maintenance the car would need. The car itself was in fabulous condition for it's age! We now have our "retirement" car to take weekend rides! Thank you to Ali and the crew for even offering us lunch! I was waiting for the weather to break (finally) to take a nice drive down the shore and we are in love! Thank you again Highline! We recommend your dealership for a good deal and honesty!
