I find it surprising that very few modern comp boats show up on eBay. There always seems to be quite a few wakeboard boats. The buyer is protected by eBay up to some amount. $50k or so. If the boat is not as advertised, the buyer can walk. The listing can be set up as an auction, a fixed price listing, or simply to field offers and counter offers. The service appears to have caught on with automobiles and leisure craft. Or maybe it's just a matter of volume and the percentage of comp boats is no different than other types of craft.
Thoughts? Would you list your boat on eBay? Would you buy using eBay? Why or why not?
