★★★★★ Best Car-Buying Experience of My Life – Tony
★★★★★ Best Car-Buying Experience of My Life – Tony Rincon, Owen Stepp, and James Wang are absolute legends at Lexus of Rockville From the very first inquiry to driving home in our gorgeous 2021 Black Onyx LX 570 with my wife and kids, including our 9-month-old baby, the entire team at Lexus of Rockville made this the smoothest, most transparent, and genuinely enjoyable purchase I’ve ever had — and we’ve bought a lot of vehicles. Tony Rincon is hands-down the best salesperson I’ve ever worked with. Zero pressure, lightning-fast responses even over Thanksgiving week, detailed photos and videos every time I asked, and he treated my family (including the baby) like his own. Tony never “sold” me — he just helped me fall in love with the perfect Lexus. Owen Stepp, the Sales Director, went so far above and beyond it’s almost unbelievable. He personally reworked numbers multiple times (including the day before Thanksgiving), honored every promise, and delivered the strongest trade-in I’ve ever received on my 2024 4Runner — thousands above every published value. Owen’s integrity and willingness to make the deal perfect turned what could have been a negotiation into a true partnership. James Wang in Finance was the perfect closer — completely transparent, no high-pressure add-ons, walked me through every single line item with patience and clarity, and made the paperwork painless while I held the baby. In an industry that can feel stressful, Tony, Owen, James, and the whole Ourisman Lexus of Rockville team turned it into one of the happiest memories we have. As a 100 % disabled veteran with a young family, the respect, kindness, and honesty they showed us meant the world. If you’re anywhere in Maryland (or willing to make the drive), ask for Tony Rincon, Owen Stepp, and James Wang. You will not find a better team or a better experience anywhere. We absolutely love our “new-to-us” LX 570 and we’re already looking forward to our next purchase with these guys. Thank you, Tony, Owen, and James — you have customers for life! Happy Thanksgiving. Francisco, Mrs. Gonzalez, kids & baby Lexington Park, MD

I was interested in a Nissan NV 2500.
I was interested in a Nissan NV 2500. Viewing several of these vehicles on cars.com and other sites. I decided to make the trip to Trust Auto in Maryland from West Virginia. About a 4 1/2 hour trip. I had talked to David on the phone to make sure the Nissan was still available and explained when I could be there to look over the vehicle. We made the trip in good time only running into one delay. Upon meeting David he brought the vehicle up to the front of the dealership and told us to inspect it, which is what we did. I had two top mechanic with me. While we knew the vehicle had been in an accident, the repair work was very well done on found a few bolts missing. One in the valance and the other from the inner fender. This could have been from the accident or just from being a service vehicle. A little over 94,000 miles on it. The detail shop did a great job on their work. Very chean for sure. After running the computer test, we took the Nissan NV for a test drive. It did not disappoint. Extremely happy with everything we saw and felt during the test drive. Steering was solid and tracked well. No pull to either side while driving. Throttle response was perfect as well as the braking system. The comfort of the Nissan NV was Avery pleasant surprise. The ride was almost as good as my Lincoln MKZ, almost.😎 Much like a 2006 GMC dually I had in 2007. Very nice. When returning to the dealership myself and the two mechanics talked things over and decided to go to the next step. After a little negotiation we settled on a fair price and made the purchase. David was very kind to us and I feel like we got a great deal. We finished the paperwork and was ready to leave but we were blocked in by another vehicle. I backed back into the parking spot when one of the ladies that worked there said she would move the vehicle so we could be on our way. She came back within a few minutes moved the vehicle and with a big beautiful smile waved goodbye to us as we left. That truly made my day😇. Trust Auto in my opinion is a great dealership and when I need another vehicle, they will be the first ones I will go to. Thank you to everyone who was so kind to us while we were there and may GOD bless everyone of them 🙏✝️🙏 Jon
Great Buy!

Just purchased m 7th truck from general manager Dennis Koulatsos. I've been buying trucks from Dennis since I first met him in 1991. He is the consumate professional, and I've referred all of my family members and dozens of friends to him, and he's taken very good care of all of them. Dennis is fiercely loyal, a man of his word, and he always goes the extra mile.

I had an excellent experience at Easterns Automotive of Sterling. Eddy went above and beyond to make the process fast, pleasant, and thorough, ensuring everything was handled smoothly from start to finish. Tony, the manager, made sure the final steps of receiving the vehicle were seamless and took care of my requests right away. The team as a whole made this a very positive car-buying experience, and I would definitely recommend them.
