Considering a '67 Dart GT Convertible as my first project. Am I insane?

Financially speaking, buying someone else’s build is almost always a better choice. But then you don’t have all the fun, or the bragging rights, and it won’t be all exactly to your taste.
About 30 years ago, I bought a 67 B'cuda vert to be a father son project. After it was taken apart, 2 operations on my spine, the sons drug addiction, even a insect called power post beetle, combined to move the goal out of my reach.
In 2004 I bought a 67 notchback at ebay. 3 different planes to reach Samamish Washington. The trip clock to home showed 2854 miles. That was 3 and half days. I consider that alone to be bragging rights before I mention my console mounting brackets, DeMonIVR, custom rally inst' panels, etc.., that stemmed from this purchase. I can claim/brag that a lot of owners are happier with theirs because I bought this one when I did.
Over the years we have got much enjoyment from driving this car, the car shows and cruise-ins, all while shielding our eyes from the the vert project that is still scattered here. Nothing but grief stemmed from that purchase.
