Working on an old vehicle that has a lot of challenges can be like going on a long road trip and wondering if you will ever get there. When you finally arrive it is very satisfying.
Being an aficionado of long road trips, remember that the point is often not getting to the destination, but all the things you'll see, experiences you'll have and people you will meet along the way that is the point of the journey. I'm sure you will meet many helpful fellow travelers here on FABO!
