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.

Purchasing a certified pre-owned X3 from Habberstad was handled in friendly, efficient and professional manner. I saw the car on the website and first texted to check availability, our salesperson Joselyn set up an appt next day to look over car and test drive. The actual closing of the deal was also easy, very straightforward on price, dmv with no hidden fees or surprises. Joselyn worked with our insurance broker to expedite getting cards and we picked the car up 3 days later. Tutorial provided was helpful and informative. Start to finish in less than a week. All done w

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.
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.

Extremely Happy working with Mary Kodak with both our family cars purchases. Looking forward to purchasing a SUV with Mary as soon as the one we're looking for is available. First purchase was a 2016 E350 and the second was a 2017 S550. Mary made us feel cared for and was extremely efficient. Very happy with Mary
