They can sit on them forever, if they want.
The places that spit out the cheapest prices on Cycletrader, are usually the ones that always spit out the cheapest prices. I doubt they'd pick up a bunch of leftovers if they can't move them at that price.
One place has '03, '04', and '05's, and claim more of each year is on the way.
I use cycletrader of an indication of how cheap a bike can be.
Yeah, if I see an '03 SV1000 naked like I want for $5000 in your town, it isn't worth it, if I can find the same bike for 5-600 or so more.
It does give you a little bit of bargaining power if the local dealer wants to sell.
