For now, none of us know the whole story. I would cut them a little slack.
Buyers always need to do their homework first. Assume nothing.
Personally I am not a fan of just walking into a classic car dealer and buying a car that is finished. I have a lot more respect for guys that dig cars out of shelter belts, old garages, warehouses, etc. - and then they invest their own blood, sweat and tears into the build. But maybe that’s just me.
