I've filed a chapter 7 and it's discharged. I have a car, it's in my fathers name...?

If you want to get something that will lower your payments, save and pay cash for something used. If that bankruptcy is pretty recent, you are going to have a very high interest rate on any car loan. High interest plus the depreciation will put you upside down very quickly, especially if you drag out the loan for more than 3 or 4 years.
