making a long story short:
a frame came in. 2 obvious once-bent-and-tried-to-bend-it-back marks around where headtube meets the TT and DT.
not a damage from transit, as there's a rusty gap between the lug tip and the tube. it's been there for at least 10 yrs.
seller had seemed a decent guy, guessing from all communications and promptness. so.

1. emailed him first saying there are bent marks, and would like to return it for full refund.
2. seller says didn't notice, it must have been in transit and suggest me open a case w Ebay if i'd want a return/refund
3. open a case with Ebay, describing all situations. Ebay says it's no-return auction, but i'm in "Buyer Protection" program.
4. Ebay sends me a message that the seller 'responded'(whatever it means), and they are in 'investigation'. should the 'final decision' be made in 72 hours.

ok. so as smooth as it sounds—(i know i am not that positive on the result, knowing i'm already screwed)
here is my question out of curiosity?

what is the common configuration of Ebay's "Final Decision"?
ie) 'seller's right so shut up and build the bike with bent frame' or 'buyer is right so seller should accept return and refund the f$%^& money to the buyer' sorta verdict?
and how hard it can be in terms of 'enforcement'?
for instance, do they force seize the paypal money back from the seller if seller seems wrong?

i am not trying to put lotta expectations onto it, taking 100 bucks for a lesson fee.
just wondering if anyone been in a similar situation.

thanks
