2004 Prius available for students, faculty and visitors to the Academy for short trips while I am at work. Daily and overnight rentals are possible with prior planning. Since I commute in it daily, advance reservations give me time to make sure it is cleaned up of clutter and has plenty of gas.
Car gets 40 MPG with your driving, so lets say 10 cents per mile. As long as you return it with at least 3 bars showing you can just pay me cash for the gas/miles you used when you return the key and not have to fuss with refilling it.
