Although the SL is a dated machine, I for one still feel it looks superb from any angle, is deffo a future classic and would only part with mine in exchange for an 888
As for values, I looked at many mint piles of shite till I found mine, If you are in no rush the right buyer will come along who will pay a decent price for the right bike, trouble with ebay is that a lot of people are after summat for nowt
Good luck with the sale
