I recently purchased a 2025 Audi Q8, and I want to
I recently purchased a 2025 Audi Q8, and I want to sincerely thank Michael for his outstanding service throughout the entire process. From the moment I walked into the dealership, Michael was welcoming, patient, and incredibly knowledgeable about the Q8. He answered every question I had with honesty and detail, and never made me feel rushed or pressured. He genuinely cared about helping me find the right trim and color, and made sure I was 100% comfortable with my decision. What really impressed me was how responsive and transparent he was—even after the sale. Michael followed up to make sure everything went smoothly and even helped me get familiar with the features of the vehicle. It’s rare to find a salesperson who combines professionalism with genuine care like that. Thank you again, Michael, for making this experience enjoyable and stress-free. I absolutely love my Q8!
Most reliable car I ever drove
This car met all of my expectations. This car is very reliable. All of the features are great. Love the color. Smooth ride on the road

Exceptional Experience at Mercedes-Benz of Houston
Exceptional Experience at Mercedes-Benz of Houston Greenway I recently had the pleasure of purchasing a new Mercedes-Benz from Mercedes-Benz of Houston Greenway, and I couldn?t be more satisfied with the entire experience. From the moment I walked in, I was met with a level of professionalism and customer care that truly set this dealership apart. I?ve been part of the Mercedes-Benz family for nearly eight years, and this location has been my go-to for annual maintenance and any other service needs. Chris Palumbo, a phenomenal service department expert, introduced me to Leigh Bennett a few years ago. So when the time came for a new vehicle, I knew exactly who to contact. Leigh, along with Kevin and J. Gomez, provided an exceptional buying experience?knowledgeable, patient, supportive, and truly attentive to my needs. They took the time to understand what I was looking for and guided me toward my dream SUV, a car I?ve wanted for years. There was never any pressure?just honest advice and expertise. The team worked seamlessly behind the scenes to make it happen, offering an outstanding overall package that included multiple discounts, Mercedes-Benz Loyalty perks, and financing options at an excellent interest rate. They never said no to any of my requests throughout the process, which speaks volumes about their commitment to customer satisfaction. Kevin was fantastic in walking me through the financing options and additional add-ons, ensuring everything was tailored to my needs while maximizing value for the overall cost?whether through extended tire and wheel protection or other smart options. The delivery experience was just as impressive. My car was presented in pristine condition, and Leigh took the time to walk me through every feature, ensuring I was completely comfortable before driving off. From start to finish, the level of attention to detail and customer care was unmatched. If you're in the market for a Mercedes-Benz, I highly recommend visiting Mercedes-Benz of Houston Greenway. Based on my experience, it?s undoubtedly one of the best Mercedes-Benz dealerships in the nation, alongside the ones in Boston, Evanston, and Tucson. Their professionalism, service, and dedication to their customers make them a true standout in the industry. And if you visit Mercedes-Benz of Houston Greenway for a new vehicle, just walk straight up to Leigh Bennett (he sits right behind the reception desk!)?trust me, you won?t be disappointed. You can thank me later!
Most incredible car I’ve ever owned.
This is my second Mercedes-Benz. It’s absolutely the most incredible car I’ve ever owned. I was blessed to be able to custom order this car to have everything I wanted and more inside and out! It literally came straight from Germany to the dealership for me. It drives like a dream. It’s absolutely gorgeous. The technology inside is so amazing! It can drive economically. It can drive more sporty if you want it to. It has so many options and settings for drivers of all kinds. Needless to say, it’s pure luxury inside. You’ll feel incredibly spoiled!
