I don't know the history of the bike but just going by the pictures, the chainrings have marks and oil build up, as does the rear mech and especially the jockey wheel, dirt and oil build up, also the headtube has wear from cable rub and the bolts and some other parts look like they were not dried properly after being washed. Looking at the bike as is though, it seems to be in very good condition and clearly doesn't look to have been used much, im sure whoever buys it will be very happy.
