You pay cash for a rental car with specific agencies like Enterprise, Rent-a-Wreck, Thrifty, Dollar, a few others. Even so, we recommend that you call the individual provider of choice to find out about their qualification requirements to rent a car with cash only. Enterprise, for example, does not accept cash payments in all of its locations. On the other hand, you will need a cash deposit ID card to pay cash for a rental car with Thrifty, Dollar, and Hertz.
