I had an incredibly smooth and painless new car leasing
I had an incredibly smooth and painless new car leasing experience yesterday with Trentino Manco and his colleagues at Rallye Motors in Roslyn. I was not surprised – I have purchased and leased my last four cars with Trent’s assistance. He is always professional, helpful, honest, and trustworthy. Trent has made the previously unpleasant car buying/leasing experience a thoroughly enjoyable one. I wholeheartedly and highly recommend contacting Trentino Manco and his team if you are looking for a new Mercedes. You will be in good hands.
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 recently purchased a Mercedes cargo van from Silver
I recently purchased a Mercedes cargo van from Silver Star Motors in LIC and had an outstanding experience working with Dawn. From the moment I stepped in, she made me feel welcome and genuinely listened to what I was looking for. Dawn was incredibly knowledgeable about the van and explained all the features in a way that was easy to understand, without any pressure to buy extras. The entire process was smooth, stress-free, and efficient. I highly recommend Dawn and Silver Star Motors.
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

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.

I recently purchased a 2016 Cadillac CTS Sedan from
I recently purchased a 2016 Cadillac CTS Sedan from Victory Cars Central in Levittown, and I have to say — this team deserves all the recognition possible. From the moment I walked in, Steve, Jordan, Santiago and the rest of the staff treated me like family. They went above and beyond to make what seemed impossible, possible. My credit situation wasn’t perfect, yet they did everything in their power — every creative, professional, and honest move — to make sure I could drive away in the car I wanted, with zero down payment. The vehicle itself runs incredibly well, and while it has a few minor cosmetic blemishes (as expected for a used car), the performance and reliability are outstanding. What mattered most was how this team handled the entire process — with transparency, effort, and genuine care. Steve and Jordan were absolute superheroes. They didn’t just sell a car; they restored my confidence in how good people and great service can change your day. It’s rare to find a dealership that truly puts the customer first, and Victory Cars Central absolutely did that. If you’re looking for a trustworthy dealership that will work with you, not against you, this is the place. Highly recommended — five stars all the way! — Jefferson C.
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.
