Rental car companies are spending large amounts of money on transferring cars between their branches, in order to position their fleet for new hires. They can either use expensive trucks,  or they can let you drive their vehicles for free. Which is the best solution do you think? Yes, to let you drive the vehicles for free is cheaper! The rental operators win, you win.

To be eligible to drive a free rental car, you only need a valid credit card (used as a security against accidents and no-shows), a valid drivers' license written or translated into English, and to be over 18 or 21 years old depending on the car.
