Bought my 07 one one year ago. I paid $5000 with all the farkles listed in my signature. It had 6,000 miles on it.
Forget KBB or even NADA. What is the market saying? Check local Craigslist and even eBay. I also check local newspapers. What may be a fair price in one part of the country is not in another, so asking this group may not be too helpful unless someone close to you can give you recent sale information.
BTW, if that bike was in Portland, OR I think it would be gone by now.
