Mercedes of Massapequa makes shopping for a car easy and effortless. Albert helped me through the whole process of buying the car and getting the best deal possible. 100% recommend this dealership and make sure to ask for Albert!
Exceptional Comfort
I have had this vehicle for only one month so have not developed much experience with it. I did take it on a 1400 mile trip two days after purchase. It ran well, was very comfortable to drive, made for a very easy trip, was great on gas mileage, and it is very quiet inside the cabin. Seat comfort is exceptional and this, being our first experience with heated seats and steering wheel, was most enjoyable.

Nelson helped us very easily end an old lease and set up
Nelson helped us very easily end an old lease and set up us beautifully with another. Nelson was very respectful of our needs and didn't try to push us into anything that we didn't want. He made the whole process painless and made sure that we were set up in the car before we left the dealership. Went in late on a Saturday and by Monday, we drove off in our new car. A++

I was torn between two dealerships, but this one made it easy. They confirmed everything ahead of time, had the car ready for the test drive, and even started the paperwork while I was still on the road. It was professional from start to finish—exactly what I needed.

Holman was amazing in assisting me with purchasing my first ever car. He explained everything perfectly, and was so kind throughout the whole process. Going into this, I was nervous as I had never purchased a vehicle before. Holman made sure everything went as smooth as can be for a first-time car buyer like me. I’ll definitely tell everyone in the market for a vehicle about Magic Auto Sales, specifically HOLMAN because he’s the man! In his eyes, the customer is the most important part of his career as a salesman. I think that’s hard to come by these days. Wonderful experience and very competitive price points. 10/10!

We just bought a CPO 2022 S580 Mercedes!
We just bought a CPO 2022 S580 Mercedes! Joe Horneman was our salesman, and he was an absolute joy to work with. There was no pressure, and he was very accommodating to our needs. We'd been looking around at multiple dealerships and no one treated us like family as Joe did. Throughout the entire process, Joe was patient, knowledgeable and available to us for questions and discussions. This is my 8th MB purchase, and I've found a new dealership to work with, and a new salesman!!

I recently had the pleasure of visiting Mercedes Benz of Nanuet, and I couldn't be happier with my experience, all thanks to Joe Horneman! From the moment I walked in, I was greeted with a warm smile and a genuine willingness to help. Joe's knowledge about the vehicles was impressive, and he took the time to understand what I was looking for. He wasn't pushy at all; instead, he patiently guided me through the options, answering all my questions and providing valuable insights without any pressure. I felt like he really had my best interests at heart! When it came time to test drive, Joe made sure I was comfortable and excited about the car, and he shared all the amazing features that truly make Mercedes-Benz stand out. Even after the sale, Joe followed up to ensure everything was to my satisfaction, which just shows how dedicated he is to his clients. Overall, the service at Mercedes Benz of Nanuet was top-notch, and Joe Horneman truly made the car-buying process enjoyable and stress-free. If you’re in the market for a new ride, I highly recommend seeing Joe—he’s your guy! Five stars all the way! 🌟🌟🌟🌟🌟
