I'll throw in a couple cents of my own.
As to fine(r) guns and not Uncle Joe's Savage 99*, Yukon prospecting or not, the gun will have some level of individual craftsmanship and therefore history in it. The car, excepting the top-end hand-built stuff, is an industrial product that came off an assembly line, built from interchangeable parts. *(OTOH, I once knew a guy who has custody of an ancestor's Civil War musket, which he'd carried when wounded at Vicksburg and brought home with him. Mass produced, but untouched and untouchable.) There is little if any comparison in the car world to the guys in the German room here telling someone who shows up with their GI granddad's war-trophy drilling who the barrel-knitters were that put them together a century ago. And then going on to telling them who the barrel-knitters were related to by blood or marriage.
I have a friend who restores expensive antique furniture. Sometimes, all it needs is a good cleaning, a disassembly, new glue (of the same type as used before - this guy boiled his own rabbit skins to make glue), reassembly, a skim of fresh finish and a good waxing. And that's all he'll do for those pieces. Maybe a new piece of wood where the upholstery nails had, over many re-coverings, had torn the substrate to pieces. Or an appropriate reinforcement. OTOH, I've seen people bring in an old 3 drawer chest in pieces, literally in plastic shopping bags. A couple months later, it left looking as new as it did 200 years ago when it went into a horse-drawn wagon from its maker's shop. About that one, we joked that he was causing a family feud.
Guns have a lot more in common with that furniture than they do with a car.
