Avis's St. Rose Parkway branch is a small, independently run car rental agency serving the greater.... 7-Hills/Green Valley area. I have only used them a couple of times before and.... it's a typical car rental place.
Prices can range from $$$$$ to dirt cheap but they do try and stay competitive. I guess if you need a rental car for a weekend trip or because your car breaks down, this would be the place to go.
