I arrived at 9:45 AM to pick up the car that I booked for 10:00 AM and didn't get the keys until about noon. There was one employee covering both Avis and Budget at the downtown DC location, and he was working really hard and being very efficient, but he simply couldn't keep up. The gas tank in the car was not full, and, after driving about 100 easy miles, the oil light turned on shortly followed by the braking system light and several warnings about the lane departure prevention and adaptive cruise control systems. The agent at the CHO airport location was not remotely concerned about the state of the vehicle when I called and asked for advice. As a result of the late start and the slow, limping conclusion, I had to extend my time with the car and pay extra. I don't plan to rent through this service, Budget, or Avis ever again.
