Rental agents rent cars and other forms of transportation for private use by clients. They are employed by car, boat or creation companies at airports, resorts, marinas and at offices strategically located throughout the country. Agents not only rent cars to clients, but also they may offer them other types of products, such as car upgrades, GPS systems or additional insurance. Although the car rental agent’s primary job is to process paperwork and collect money from clients, agents often have a lot of other duties they perform as well. Car rental agents typically have the task of greeting clients as they arrive, answering the telephone, handling client questions or complaints and working to resolve overdue car rentals. In some cases, they may also be responsible for ensuring the cars are clean, full of gas and ready for the next client.
