We had a straightforward, no hassle, seamless car buying experience at Ewing. Our salesman, Clayton, made the entire process easy for us from trading in our ?problem vehicle? to finding us the exact car we were looking for and having it delivered promptly. There were no salesman tricks, no hidden fees and no pushes to purchase extras we didn?t need. All around great experience. Highly recommend!

After searching for over a year for the right truck, I made several unannounced, walk-in visits to Ewing GMC in Plano. Every single time, Josh Manning and Clayton Hass were exceptionally responsive and professional. Even without appointments, they made sure I was fully taken care of?quickly, courteously, and without any pressure. Their communication was clear, follow-through was flawless, and they consistently respected my time. In an industry where service can be hit or miss, Josh and Clayton set the standard. They are a true asset to Ewing GMC, and I highly recommend
