An overall great buying experience.
An overall great buying experience. Got a price lower than I was expecting and the salesman Jean Joseph was great to work with.
2021 GLC300 4matic
I absolutely love this compact SUV! Coming from a Subaru Outback, this is light years above and beyond for same year. A quiet cabin is my top want for buying a car. This cabin is quiet and relaxing inside. I’m tall and there is plenty of room. The seats are incredible! Can’t wait to take it on the roads in winter.

The entire dealership staff at CPM was incredibly
The entire dealership staff at CPM was incredibly welcoming, making the process smooth, efficient, and completely hassle-free. I got my Jeep Compass Latitude from them, and the experience exceeded my expectations. If you're looking for a top-tier car-buying experience, I highly recommend CPM and working with Jeremy - he made everything seamless and enjoyable.
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.

this was the second time that I was in for what I consider major repairs. Initially, the service tech and I didn't hit it off very well. Then Tim the service manager stepped in and was great to deal with. The repairs were completed in good time and they did a fantastic job. I'm happy I chose this dealership.

I just bought a CPO 2024 GLE 350, beautiful car, incredible ride,performance,luxury . I didn't think i4 turbo engine was going to be this powerful . I have GLS63 amg but this car drives amazing I don't miss the GLS. It was fast easy pleasant buying experience, at the end I had a minor problem but it was resolved. After driving this amazing car I forgot about it. Silverstar is my dealer and I service all my cars here. If there is any problem at all they have a great management and take take of everything. I usually buy cpo cars, extremely well maintained and serviced vehicles. If you're looking for a best suv for money forget about X5,Q7 Cayenne or Range Rover get a GLE 350, you won't regret it. Amazing car. Don't believe me take a test drive.

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! 🌟🌟🌟🌟🌟

Top salesman with a reputable dealership !
I have been purchasing MB automobiles from RVC MB since the 80’s .. I’ve always used the same salesman , Mr Tom Ahrens . Tom has always ensured that my new car purchase goes as smooth as possible .. I’ve always shopped price prior to making the deal - Tom has always beaten the competition prices - a great car coupled with a smooth transaction and a caring salesman working for a reputable dealership works for me !!

Steven David Benzel Busch
I rarely write reviews and for the very few times I have done so in my life time, it was always to point out a bad service. HOWEVER. I had exceptional experience purchasing my E400 Coupe with Steven David from Benzel Busch. Since getting my first license back when I was 16, I bought and sold 10 different cars and Steven by far exceeded any of the sales person I have worked in the past. He was very responsive to all of my emails and phone calls. I almost got a reply back within 5 minutes from sending an email and we had many emails back and forth as I was purchasing a vehicle out of state. He was very detailed and truthful when describing a vehicle that I was purchasing. There were few times where he reached out to me first on items normally you wouldn't expect sales person to. Thank you, Hyunbin
