The best salesman
Giovanni is one of the best salesman that I have ever met he does a great job ..I bought about four cars off of Him he does great service. And gets the deal done. ….
Best SUV we've ever owned.
Exceptional vehicle in the SUV class. We drove the BMW X7, Audi Q7, Volvo XC90 and this GLS 450 just kept blowing them out of the water. The ride is amazing and we feel the comfort level and size is the best

Best experience and fastest total transaction I’ve had in
Best experience and fastest total transaction I’ve had in my car buying experience. From the easy access to the dealership off the West Side Highway, to the amazing environment they’ve created inside, to sales consultant Gregory Gazzola’s expertise and ability to read a customer and deliver the vehicle I wanted, at the price I could afford, expeditiously, it was absolutely the best experience. I emailed Gregory this morning, he found me a vehicle, presented a deal, and gave me a pick up time for earlier this afternoon. I was in and out of the dealership in less than an hour today – I’ve spent more time in Home Depot buying a grill. I highly recommend Mercedes-Benz of Manhattan and Gregory.
You get what you pay for
We are in our first five months and I seriously believe all the safety options have kept me out of at least two accidents. The car on the highway practically drives itself while giving me a message. Audio systems are excellent. The 450 GLS makes driving a bit of a joy.

Best Experience Car Shopping Ever.
We found ourselves looking for a car in a very buyer unfriendly environment. After several discouraging experiences at other dealerships (including our previous Mercedes dealer) Ray Catena of Freehold was a refreshing experience. When we showed up our salesman John Farrell was ready for us with the vehicle we were interested in. The Manger Leigh stopped by to say hello and I was promptly connected with a representative to take me on a test drive. John was incredibly considerate of our time. Rather than sitting to wait and keeping us hostage at the dealership, he ran the numbers and called me later. We quickly agreed on a price and 24 hours later he delivered the vehicle to our house. In total I spent no more than 90 minutes driving, negotiating the agreement, and signing paperwork This is the most pleasant and easy experience we had buying a car and we have been working with Mercedes Benz for the last 10 years. I cannot recommend this dealership or John Farrell or Leigh Farrell more highly.
Great car!
Luxurious to drive and very quiet riding car. I am very satisfied with the car. The electronices are a bit over whelming at first. Love the car.

I had an excellent experience at Fast Track Motors.
I had an excellent experience at Fast Track Motors. From the moment I walked in, the staff was friendly, knowledgeable, and genuinely helpful. They took the time to understand what I was looking for and helped me find a vehicle that fit my needs and budget perfectly. The buying process was smooth, transparent, and pressure-free. I appreciated how clearly everything was explained, and there were no hidden fees or surprises. The vehicle I purchased was in great condition, clean, and exactly as advertised. What really stood out was their customer service—responsive, professional, and honest. Even after the sale, they followed up to ensure I was happy with my purchase and answered any questions I had. I highly recommend Fast Track Motors to anyone looking for a quality vehicle and a dealership that truly cares about its customers. I’ll definitely be returning for future purchases!
Great Electronics and Engineering
This car is state of the art in human factors engineering. It has multiple layers of safety enhancements. Interior is very spacious. The 42 volt battery provides quick acceleration which allows the car to have no lag time when accelerating.

Great Tech Service
I recommend anyone needing service for their Mercedes Benz, choose service tech Buddy Lim. Definitely a step above the rest, if I could leave a cash tip, I would. Straight forward and honest. In fact when I upgrade my car, I'm going to ask Buddy which salesman to use, if he trust him, so can I.
