Yes you can if you have a fair credit score.
Whether your car loan is discharged by a bankruptcy or not will depend on your state and the equity in your car. Whether the loan will be discharged or not is called an "exemption".
Has to
Yes. In that order.
If there was a secured loan and you reaffirmed the debt in your chapter 7 and you have paid off the loan, you should get the title from the lender. If you surrendered the car to the lender in your chapter 7, your balance was discharged as an unsecured loan and you have not owned the car since you surrendered it.
If the lender is willing to reaffirm the loan with the borrower then the vehicle can be returned. A vehicle is a secured debt and is not subject to chapter 7 bankruptcy laws.
maybe
Yes, it is an unsecured loan.
If your asking can you keep your car in a Chapter 7 bankruptcy, the answer is yes, if the value of the car less than the total of your state's exemption for personal property. If there is a loan on the car, then the value of you car is probably 0. However, if there is a loan, you must reaffirm it in the bankruptcy. This means that you make a new promise to the lender to pay the loan even though it was discharged in the bankruptcy. Usually, you must be current in all of your car payments in order to reaffirm the debt.
No.
I have been through Chapter 7 twice and both times was unable to claim my Student Loan.
Student loans are exempt from bankruptcy as are IRS debts
No. You probably didn't include the car loan in the bankruptcy (if you did you wouldn't have the car anymore). If debt wasn't included in the bankruptcy you still owe it. Was the car insured? Usually if there's a loan on it the loan holder requires full coverage insurance. I'm not sure what the line of credit has to do with the car.... but if that line of credit account number was included in the bankruptcy it will/was discharged.
