Looking at used Diavels. With the advent of the 1260 and X-Diavel, I guess that prices for 2013-15 Diavels is going to get pushed down a bit? From what I have read, the 1260 is a significant improvement over the old Diavel. I've seen bikes on ebay auction not make £7k. A lot of people are asking over £8k. Any thoughts on where the used price is going? Gradually downwards or off a cliff?
