100s were made in far too many numbers, and while their value might increase over time, they will never be worth enough to justify this much effort and expense. There just isn't enough of a long game on that kind of work to be worth doing, unless it's prep for some display or museum somewhere.
Might as well put your money in a pile on the ground and light it on fire.
Ya well not everyone does that sort of thing as an investment. Besides some people have a lot of money dude. The cost of that resto would be chump change to some people.
