ive been waiting on a replacement bike for a few months and have been going back and forth on selling it or keeping when it finally arrived. Well yesterday I finally got to pick it up and take it home. I'm still on the fence in what to do as far as keeping it and enjoying it or selling it. It's 2016 1299 base with 10 miles and I just submitted the paper work for title. I've seen some used ones at dealers asking 17,500, but they don't seem to sell. What is a solid price on these used?
