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.
Love this car
This car met all my needs and more. Love the interior and the way its moves. So comfortable and reliable! Very pleased with this car!

I like this dealership for my service needs.
I like this dealership for my service needs. I find their prices as good as small local places and definitely don’t feel that I am being overpriced or oversold on unnecssary services. Megan Dolce gave me exemplary service; very communicative and clear. Thank you.
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

My mom brought a car from planet Honda we were there 4
My mom brought a car from planet Honda we were there 4 hours it took a long time the sales men that work there nothing is organized my mom brought a Honda Accord in gray the people that work there will help you it is worth the money
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.
