No such thing as RISK FREE.
You make sure that it is a legitimate ebay listing and
Not a listing from Kijiji, Craigslist or Auto trader or some
other Scam Artist who say they will send you an ebay invoice (( FAKE ONE ))
and ebay will hold the money untill you receive and inspect the vehicle (((which you never
receive and the money you thought ebay was holding is actualy sitting in some scammers
bank account.
Myself I would never bid on a auto on ebay that I couldn't go and
check out in person or have a reliable friend in whatever city it is in do it
for me.
