But then what is the alternative. If you don't get the car fixed, then you will not be able to commute to work. If you won't work, then you won't be able to pay rent. Isn't the $500 loan then a better alternative than ending up homeless ?
Would'nt it be better to rack up a $500 loan and then try to pay $100 per month so that it can be paid off in 6-9 months - even with 36% interest ?
