Most "Built" use bolt in parts.

Or they sub out work

It's rare anyone can do it all themselves

build the engine
build the trans
built the suspension (not just bolt on aftermarket kits)
panel work
paint work
interior work

There is a small group that can do all of that and I am in awe of them. But they are a minority.

But for the rest of us this discussion is mute, we do what we can and get others to do what we can't
