Rental car facilities require multiple people to keep things running smoothly. There are car rental agents whose responsibilities include finding the best car to rent to customers, encouraging product upgrades and additional insurance, processing paperwork, and collecting money. As a detailer, you handle duties related to preparing the interior and exterior of the vehicles and making sure they are clean for the next customer. You can also drive a shuttle bus to and from the airport to assist with car pickup and return. Rental car facilities have management positions as well.
