You can still collect parts/think about other projects. But seriously, if you pic one to COMPLETE you will be glad you did. I had many unfinished projects over the years and as things changed, I let them go for one reason or another. I made up my mind to get the Duster 'done'. I will continue to make improvements ( Changed the front bumper today). But having it back together as a complete, painted car is just an awesome feeling...
