I'm disabled and on a fixed income, How can I get a loan for a car ?

First do you have enough income to pay for a car loan? Do you have any money saved up for a down paymnet on a car, or a old car to trade in?

Loans are based on ability to pay the loan back, so ifyou can show you have enough income to pay for the car there should be no problem, if you don't have enough income to pay for one, it is doubtful anyone but a "buy/here pay/here" place would sell you a car on payments
