I have a question for anyone with some 'legal' advice.

heres the deal,
A person i know got a new car with there boyfriend (back in 06). He didn't have any credit so in order to get it, they had her mother co-sign the loan. A few years and no problem, till they break up. Not soon after, He stops paying the car payment.

Any advice here would help. We have the keys to this car, and the debt collectors are calling the house. Should I take the car? its a grand prix btw. What other options foratke in this situation?
