Normally I don't comment on these "offered" threads but, the market value of your bike is what it would sell for at auction--which seems to be between $15-18K........To suggest that a 955SPA is less desirable that a 998R, and that the market "value" of an SPA is tanking in this economy while the market value of the 998R magically seems to keep rising, is just stupid talk.......The 955s are the rarest of the rare--I can't remember the last time I saw one for sale. With around 50 built worldwide, I would take one over the 998R in a heartbeat--that and I absolutely love the older Cagiva graphics plastered on the side of the SPA
