So..... Did the CUCV in question from 7 years ago end up holding its value?
I like both ends of what's discussed here, like said, if a truck is damaged/non running/pieces missing/previously hacked on, I see no harm in modding it, as long as the mods are not bubble gum and duct taped together. Guys who buy good to spectacular all or near original examples or rarities because they're already "pretty", just to cut them up and/or pop holes in them make me cringe, there's plenty of beat on metal out there, save the original examples to stay original examples.
In my blunt opinion, Sporterizing any firearm pre 1950 should be punishable by hard labor, I have a Lee Enfield No4 model T (very VERY hard to find) that was manufactured in 43 and from what the machine markings say, was deployed, blown up, refurbed by the RAF, deployed again, blown up again, refurbed AGAIN, re-deployed, decommissioned, and sold to the public just for some squawkhead to decide it'd be "cooler" and "better" (in his words) with more holes added, original "outdated" equipment removed, holes plugged, and equipping a Walmart Tasco scope. Destroyed most of the value it had.
Tinstar said it best, anything is only worth what someone is willing to pay it.
