I just turned in an Avis car that I picked up on Thursday at MCO. On Friday evening, I realized that the registration was expired on the car. I called Avis & they said that they would bring me another car within 1.5 hours. I waited & they never came. On Saturday morning, I called again & told them about the previous night. They told me they'd have a car out to me within an hour. They never came. This morning when I turned in the car I complained to the attendent & he gave me a $25 coupon towards a future rental.
