<prompt> Human: Im 18, starting college on August, and need a car for commuting to and from. Ive tried a few places, but all of them say I need to have a cosigner due to my lack of down payment 500 atm, and having weak credit history 5 months, 1 credit card, 604 score. I always pay my card on time to keep the score increasing, but theres nothing I can do about the history obviously. My issue is that my job is under the table. I only make tips, but I generally make 1200 or so a month, plus I have 1750 a month via GI Bill from my father. But I cant prove my work income, and they generally dont accept GI Bill as a source of income. I was wondering if I were to buy say, a 17000 car, how much of a down payment would I have to have to eliminate the issue of having to have a cosigner, or proof of income?  <response>: You cant afford a 17k car and no bank will give you a loan at a decent interest rate for any amount.
