We had a straightforward, no hassle, seamless car buying
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!

I?m incredibly grateful to have worked with Adam Drissi
I?m incredibly grateful to have worked with Adam Drissi and Justin Simpson. They guided me through every part of the application process, answered all my questions honestly, and worked hard to secure a great interest rate for my first car. Their patience and professionalism stood out, especially compared to the customer service I encountered at other dealerships in the area. Adam and Justin made the experience smooth and stress-free?I can?t recommend them enough.
