UM, you do realize that is not a legit auction right? It is a scam of epedimic proportions that is floating around ebay, auto trader, cycle trader, truck trader, ect.
I'm sure these guys get thousands of interest and if only 1% actually follows their directions, then they come out rich as a mutha fu(ka. It usaully involves them being out of the country, Western Union, no shipping fee's with a right to refund for 3-7 days, all importing work is taken care of for you. They are useing the European countries right now, like Portugal/ Spain/ UK/etc.
The deal normally works byyou putting money into WU so they can see that you have the funds-and whether you want to believe it or not there is no way to stop them from taking the money once you give it to WU.
So lets recap: 5,000 people respond(low #'s here) and 1% of that is 50 people. With 50 people putting in on average 3K each. That comes out to 150,000 in U.S. funds for an investment for about 2 weeks and the cost of the ad. I've seen hundreds of these.
STAY FAR AWAY--Ebay is aware of this problem but doesn't seems to be doing much about it. That may be because of an on going investigation/sting. So don't worry about the bike go build that motor and enjoy, because if something sounds to good to be true IT IS.
