Is there a legitimate lender for a personal loan with poor credit?

I am trying to get a car and I am looking for a lender to loan me the money for a down-payment. I have already been approved for the car, I just need $500-$1000 for the down-payment. The monthly payments will be low so I can afford them as well as pay the lender back. Serious answers please and no lending company scams!!!!! I’ve ran into too many of them online!!!
