You'll get a car that runs; just make that your expectation and you'll be fine. My rental was a '94 Civic with 300K+ miles; rusty, small dings and dents all over the place. One of the tires was out of balance and it was out of alignment. Not a great experience on the highway. My only real concern about the safety of the rental is that the seat-belt was very worn and abraded in a section of the seat-belt, to the point that if I were to have had a serious accident, the belt probably would have snapped. I could have complained and I'm sure they would have provided another car. Again, they're cheap, set your expectations low about the condition of the car, and you'll be fine.
