I may be able to get my hands on an 06' GS with about 1,000 miles on it, I was trying to figure what a good price on it was.
Is there a value Calculator like this one http://ninja250.kingston.net/ninja-value.html for the GS500.
I figure 4k or around there is a good price.
go to KBB.com and NADA, will give you a ballpark
