Not a bike purchase off ebay, yet similar:
When I was looking at sand rails on ebay and other places, forum members offered to go take a look for me before a bid was placed.
Once I won an auction I sent a $1000 deposit, then contacted several "recommended shippers" (lowest was $1800 and 4-6 weeks), grabbed a cert check and some cash, borrowed a flatbed trlr and leaving around midnight friday, drove straight thru to Las Vegas 1100 odd miles, spent about 2 hours going thru this and that, loaded up /fueled up/ got some grub/ checked out prices on air conditioners (home depot was out) and headed home. An hour north of vegas I was too tired to drive anymore, so in 109 degree heat, I slept with all windows down ffor a few, then arrived home late sunday evening. I spent $560 on fuel and some food and gave my bud $100 for the use of his work trailer. Saved over $1100 and the rail was in my garage 3 days after winning the auction.
Use due diligence and enjoy what you bought.
