Hmmm... How about running reverse auctions as a user selectable alternative to the essentially classified ads that the above scenario describes?
Say I have a secondhand power commander for a GSXR1000... I put it on your site at $600. After a time period I select, it drops by an amount I select... say $10 every 3 hours. People can watch it all they like... as soon as it drops to a happy place for them, they hit the buy now button (no bidding, just buy now).
Potentially it could help to generate not only traffic, but regular traffic. People have to continually visit to watch the prices, plus they need to continually visit to see what's available. Add in a few google ads... suddenly the site is not only making you a buck, but paying for itself in the process
There's some details to work out, system, process and techinical, but I'd be happy to consult on that (for nix) if it interested you.
Another potential gap in the market you could fill could be a wanted section... e.g. I want a clutch cover for a GK71 GSXR400... that sort of thing doesn't just appear on trademe every day, but if there was a list of parts wanted that people with crap in their garage could scan, then it'd help them move odd stuff, and help people to find odd stuff. Could be a winner?
