Thinking about upgrading soon, the old girls are getting a bit old...
would it be wise to find a low hours 15, and go from there or do you think i should wait a little longer till there is some sort of "new" production from the new GG team.?
I just bought a low hours '15 and am very happy with it. My guess would be that the '16 will be quite similar to the 15, as they have little time to do development. So if you are after a better bike than the '15 you'd have to wait for the '17. The plan is to make only 1000 enduro bikes in '16 according to the rumours.
So if you can find a low hour '15 I would not hesitate to buy it.
Please note that 2016 production will be extremely limited. So there is no guarantee that You actually are able to get Your hands on any new production.
