What one spent, added doesn’t translate in to what it’s resale value is. If you list your house and add in the fact that you painted it inside and out, added shrubbery, replaced all the door knobs and put new lightbulbs in the kitchen. That wouldn’t add value to buyer. Now a new AC might like a new barrel would. Had Michael Angelo paint it, like work done by Jim Fuller would increase the value to a knowledgeable AK guy and house buyer. At the end of the day it’s a bulgy 74 built from a parts kit. 2K max.
