It depends on several\a number of things, including service history, provenance, condition etc. etc. The mileage is clearly low and no doubt little used over that time. Your best bet is to look at Ads for the same bike and see where your bike fits in. Of late, particularly, the more "desirable" 748's have gone for a greater asking price that I would be prepared to sell any of my three 748's for, some of which are in the greater and more desirable category, and I personally think the asking prices have been too high. It really is for you to try and see where yours fits in. If it is a stock biposto then it will not be worth as much as the 748 SP\SPS\R group. Perhaps a few photos could on this forum could give you more feedback? Purely my experience of dealing with these models and others can no doubt also inform you.
Varies massively - I just missed a similar one for £2500 - snapped up in 2 days of it being advertised. So £2500 upwards
I think you should open it up 3750. Boggo bipostos at the 4000 mark don't seem to shift that quickly Might be worth noting that a tidy 15k mile sps recently sold for less than 5k and it was very straight
I do feel that whatever you spend on getting it serviced or recomissioned prior to sale you won't recover fully so I would leave it open for discussion and price the bike as is
