I have only tried to rent with them once. It was President's Day week and they tried to give me a car that I felt was not a midsize (I think it was a Corrolla, but I can't recall.) When I questioned the agent if this was a midsize he said "It is this week, we adjust the car sizes when we are busy." In other words the week before this was NOT a midsize, but rather then upgrade me to a full size or give me a discount for a smaller car they just call whatever they have a midsize. I walked!
