bad credit, i need a car financed, already have an auto loan out?

okay heres the deal
i have an auto loan out on the car i am currently driving. i want to take a 3,000$ loan out for my daughter next month so she can have a car that is reliable.
i have bad credit, and not much money to put down either, i cant get a co signer either unless it is my daughter. she has no credit because she just turned 18, but she doesn't have anything against her yet.

we have about 500$ to put down on this car.


any tips? there are a lot of in house financing places around where we live so were gonna try to go there. will they want more for a down payment? do they make you get insurance right there or can you get your own when you leave?
