Have you ever tried to rent a car with cash?
Can’t be done.
That is a business decision by the (major) rental companies. This is a state imposed mandate upon ALL 'second hand' sales, INCLUDING Salvation Army, Goodwill, flea markets etc.
How many booth holders at flea markets have Credit/Debit card capability, and are willing to take the transaction fee hit? How many take checks?
How many homeless have the credit cards or checking accounts WITH "acceptable" ID to make purchases in thrift shops, where they had been using cash?
I MIGHT understand and approve of certain business being required NOT to pay cash for items offered to them; but what purpose is served by CUSTOMERS not being able to pay cash for merchandise?
IF if it so compelling, then why are PAWN SHOPS exempt?!?
As to your original question, you're a bit outdated:
Cash Only Car Rental Here's another source for cash-OK car rentals, complete with a partial list of U.S. airports that have cash car rental companies available.
Rent-A-Wreck also rents to cash-only customers.
