Lexus dealerships near me (Warrenton, VA)

I had confirmed an appointment, I was assured the car was available. I was told that people had driven it and were interested in it. I was driving from Baltimore to Rockville for the appointment. 40 minutes into the trip. I was called and notified that the car had not passed inspection, yet had been told on the phone that the car had been test driven by customers the day before. How is this possible? Dishonesty, one way or another.
