Kelley blue book is the best way, 13,500 miles is a fair amount of miles when your trading it in, even though it may be in stellar condition, you probably wouldnt get much more than that for it, cuz they wanna make a profit too. If you sold it outright you could MAYBE squeeze another 500-1000.00 out of a buyer..but that'd be pushing it, IMO>
congrats on the new ride, be sure to put up pics of it, and let us know how you like it!
Thanks again everybody. I just told him OK on the deal and the bike is ordered. I can't wait. Not that I can go anywhere with snow & temps around - 5 but I can still stare at it in my garage. Anybody going to Myrtle Beach for bike week this year ?
