Those prices on the new ones are good. I'm not sure about the '07 there aren't usually a lot for sale here anyways. The Kawi list price on the 2011 started off this year at 8999.00 and then dropped to 8499.00 around April (of course just after I bought mine, I paid over 8 but not list). One dealer here now has the new 11's at 7999.00.
It is definitely a smaller market but I think it is because a lot of people aren't aware of the bike and Kawi doesn't seem to flaunt it but to me it is the best, most fun bike to ride I've owned out of several.
Resale value or not it is a bargain for any of those prices you've mentioned.
