How do i get what i want?

I have no credit and I have no bank account. I only make $700 a month. However I have no expenses and no bills because I live at home with my parents. I have been trying to get a car recently and i have been turned down for financing every time. If I get my father to co-sign for me and come up with $2000 in cash and a trade in, is it possible for me to get a loan on an $11000 vehicle with payments around $150 a month. My father doesn't have great credit but he did just pay off a car loan with a giant interest rate without missing a payment. would he be a strong enough co-signer. also how does a co-signer work. If my father co-signs do i get his interest rate and do they run all the negotiations threw him then or is it still me. and if I cant how much of a down payment would I need for the bank or dealer to just forget the fact i have no credit and no bank account when trying to buy an $10,000 or $11,000 if anyone knows about this stuff that could really help me it would be aw some thanks
