My wife and I just purchased a 2018 Lexus RX 350 from Lexus of Rockville. We are overwhelmed with joy! Our salesperson, Kewai (Kay) Wu, really set the bar with outstanding customer service. From the time we walked in the door to the day we drove off as new owners, he has been right there to answer every question we could come up with. Kay took his time with us to show us many different models and colors, explaining all of the exciting technology as we went along. His openness about pricing is what really sealed the deal for us! I will recommend Kay and Lexus of Rockville to all our friends who are considering buying a Lexus. My wife also enjoyed the "Lexus Technology School" she attended taught by Bernie Kitts. He spent a couple of hours showing her how to use every bit of technology that comes with the RX 350.
