Which adds nothing to the price
Probably not but the flip side is that it strengthens his position with regards to people trying to barter the price down because 'it might need a new clutch soon'
Yes of course, and if I was looking at 2 identical Zeds, same year, similar mileage and one had a reciept for a brand new clutch then I would go for that no question... but would I pay over the odds for it, no. Same goes for tyres, brakes etc etc etc they are all consumables and can be factored in but not really used to push a price up in my book anyway and as you say more of a reason to barter down than set a higher starting price
