That stuff never bothered me much. I buy a lot of my used parts locally... but maybe that's just a luxury of being in the DC area. Of course I'm real picky about parts and I have weird tastes so I end up buying from cool people anyway just because they're the only ones with nice rare stuff for sale.
The only thing that really bugs me is the small number of people who won't ship small stuff.
If you don't want to ship body panels and engines, that's cool, but not wanting to ship headlights? Calipers? Control arms? WTF? If someone's willing to eat the cost, I'll ship anything I've got that UPS will actually take.
