I want to buy a Used Scion tC I make about $300/bi week, and I plan to put 2K down on a tC valued at 8500 or below, and the rest will be financed. My dad doesn't want to co-sign, he says I wont be able to afford the month payments w/ Insurance. He claims dealerships will not sell me a Used car, unless i'm going to put full coverage on it. No matter how much I put down. Can someone clear this up for me?
