Great experience at this place! Hamad was very helpful and patient, he made sure everything was understood even if he had to repeat it a couple of times. Throughout the purchasing process he made sure we were entertained and kept checking in on us and asking us if we needed help with insurance of had any questions. I highly recommend Hamad, we got a great deal!!

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.

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.

Exceptional Service and Dedication at DARCARS Lexus of
Exceptional Service and Dedication at DARCARS Lexus of Greenwich! I recently purchased a car from DARCARS Lexus of Greenwich, and I can’t speak highly enough about the exceptional service I received. From the moment I arrived, the team made me feel valued and ensured every detail was handled with care. A special thank you to Brooke Jessup-Labonte, who truly went the extra mile—literally. When I decided to sell my old car through CarMax, Brooke offered to drive it back to my home, spending over several hours in unexpected heavy traffic. When an issue arose with the payoff information, he handled it seamlessly, contacting the dealership and Toyota to resolve everything on the spot. His kindness, patience, and professionalism left a lasting impression. I also want to recognize the incredible teamwork of Dave Miller (Manager), Andreas Tsirikos (GM), and Michael Tuzzio (Manager). Together, they made what is often a stressful process feel smooth, efficient, and even enjoyable. I’m absolutely thrilled with my new car—a Lexus that I instantly fell in love with during my visit. It’s a perfect fit for my needs, and I’m grateful to the team for helping make it happen. If you’re looking for a dealership that values its customers, provides impeccable service, and goes above and beyond, I highly recommend DARCARS Lexus of Greenwich. Their dedication and care made this an unforgettable experience, and I wouldn’t hesitate to recommend them to friends and family.

I submitted an internet inquiry overnight, and as soon as
I submitted an internet inquiry overnight, and as soon as they opened, Ephraim Senteio promptly reached out to me. I was very upfront about my busy schedule running multiple businesses and mentioned that I didn’t have time for window shopping. Ephraim completely respected that and connected me with Client Advisor Sam Al-Hajjaj, who was absolutely phenomenal. Sam worked efficiently to provide great pricing and handled my trade-in with care, making the entire process seamless. Jake DeMattia from the Genius Center was incredibly helpful, ensuring I had all the information I needed about my new car. Danny Rodriguez in finance was both friendly and efficient, making the final steps of the purchase smooth and stress-free. I purchased an X5, and I couldn’t be happier. 5 stars! My only feedback, as someone who frequently purchases high-end vehicles (Range Rover, Aston Martin, Acura, etc.), is that the dealership can get very busy and you can tell the staff was overwhelm, I think some technology could help them because people would get lost in the waiting room like we did :). This is understandable, especially on a weekend and the last day of the month—partly my timing. Overall, I look forward to building a long-term relationship with this amazing team. After almost 10 years, I’m thrilled to have a BMW back in my garage. Highly recommended!
