I have bought & sold on E-pay for many years without issue, but then I'm pretty picky about my purchases & either try to get new items, or make sure what I'm bidding is what I want.
I have gotten many many parts off the site, found it invaluable in finding odd parts for the Bomber, bits & pieces for my Coke machine, and now even more so for the GMC (I got a NOS Hydrovac, in it's original box for $24!!).
MY personal peve tho, the butt darts that use auto bidders. they dont have the guts to actualy bid against you, no they use this automated thing that hammers the bids in at the last 5 seconds via a high speed connection till it wins or hits the cap amount the bidder sets. Got outbid that way 5 times in a row trying to get a Vega steering box,...

BTW, if anyone is looking for rare hub caps, look up Pearsons Auto Wrecking & Hubcaps near Ridgecrest CA. They have caps for darn near anything you can think of & ship world wide. Lost of neat old cars too, & last I was there they had a stack of old bolts as well.

1956 GMC 370 dump " 'Tater "
1970 VW Volksrod "the Black Bomber"
2007 Chevy Avalanche
2020 Jeep Cherokee Trailhawk,
2005 Harley Davidson FLHTCUI

I dig all cars, old and new, whether they were hammered out of American iron, German steel, or Japanese tin cans. Being unable to appreciate them all is missing out on a world of great things.
But thats just MY opinion! :P
