That is a seriously cool piece of history, but you have to weigh the 'mom tax' against the fun of the project. Looking at the photo, it has incredible potential for a family build, but 30+ years of sitting means you'll be replacing every piece of rubber, wiring, and the entire brake and fuel system. If you decide to go for it, my biggest advice is to have her sign the title over to you completely before you load it onto the trailer. If she won't do that, the strings are still attached. Otherwise, it could be an amazing memory with the guys!
