Got any advice?

My mom wants to sell our Duster. I want to keep it and work on it when I get the money. It was my dad's car, but he passed away 13 years ago. How can I convince her to stop posting ads and trying to sell it? People keep calling about it and i'm nervous it'll sell soon. The car means a lot to me, and I would hate to see someone else get ahold of it.

Anyone got any advice or been in a similar situation?
