I hope that everyone who responds to this survey will let them know that not only will they not pay extra for low-mileage cars, they'll stop renting from Hertz if they keep crappy cars which are not maintained properly with high mileage in their fleet.
I just got back from Hawaii and both Hertz rental cars I had were almost brand new ! I can't stand when I rent cars that have more mileage than my own at home.
