Well, I'm not a good one to ask about values etc 'cos, well, I'm crap at that sort of thing; plenty of others on here seem to have a good idea though...........but, to put it's price into context, mines a late '14 and came with a free 'travel pack' as part of a deal KTM were running at the time (as they always do at the end of a year). This included sump guard, heated grips & full bread bin luggage (I think that was all of it). Other stuff I added at purchase was supplied at cost as part of a deal with the dealer. I paid a smidge over £14k. Based on that £9k for yours seems a bit high but, like I said, what do I know........
It doesn't look like it's got many miles on it (nice and tidy)

On a MY13 you won't get the fancy 'lean sensitive; TC and ABS (introduced MY14) and there's a question mark over how well the airbox seals right up to about MY16 (I think). I've modded mine as have others and my airbox is clean as a clean thing. Having said that I know people who have left theirs alone and their airbox is as clean as a clean thing.......................
Heated seats are nice (but not needed due to the hot rear pot) but everybody who has them says how comfy they are.
Er..............I can't think what else to say really......they are brilliant bikes and I love mine; three years down the line I still sit in the garage and just look at it not quite believing I've got such a cool bike
Oh, and congratulations on you new life of leisure
