reworking a fully restored car

wow! I do my own work, good, bad, mediocre, great, whatever, its all on me.
decades ago I had couple of guys that did my paint/body.. I spelled out exactly how I wanted it, bought all the parts, paint and materials, I paid them labor and looked at their work every week EVEN though I would trust them with my life!!!! just business///
I see people on here that send cars off to the resto shop that I would never think of such without blasting it to see what if anything would even be left!???? maybe then when some unscrouplous shop decides they found mr. money bags!// its not right, but s*** happens???

I hate to see people get screwed, but.... 50 grand to do a 318 car??????
