Thanks Oliver.
Maybe peoples expectations of value are different, the wheels are priced at over £200 retail, trade price close to £115, the tyres, if considered new (only 2 miles done) are @ £100 each fitted. It follows therefore that a full set of 4 = £860.
My suggestion of £650 does not see unreasonable on the basis that buyers are taking it on trust that I am telling the truth about mileage covered etc.
We did have one offer that came close to acceptable, but have decided to withdraw from sale on the basis we are going to fit winter tyres (original plan when bought) and keep the Pirelli's as spares for our new car
Should keep us going for a year or two!
