My brother passed away. He left me his car. What to do?

Wow you have a lot going on right now. If I were you, I would sell your Nissan. Being worth a little less, it would sell quickly. And you would have to wait for all the paperwork on your brother's car to clear before you could sell it. In the meantime, talk to your local churches and see if anyone can help you. People tend to be more generous than you think. Best of luck.
