This is kind of a long story. I am 17 and i am paying for a car through my dad's name. He has crappy credit. Thus im making $400 car payments a month for a 97 maxima. And that is through the actuall auto place, not a loan through a bank, the auto lot financed it for us. Is there any way i can trade this car in for a cheaper monthly payment? i mean ill still pay off the balance, i just need to get this 400 a month to at least 200 or something.. im almost positive i cant do anything till im 18 but i still wanna know if anything like that is possible, because i know all im doing is building my dad's credit not mine..
