depends on service history, condition, state of the power head i.e. can we tell if someone has opened it up, has much the paint has flaked off. Also controles, gauges and recipts along with usual test.
Oh and before the one at 2200 is classed as v expensive the owner still had the original box and dates and hours when used which came to less than 100 and it had be stored properly.
for the £800 think the oposite i.e. no controles etc.
I took at look at that so thanks for the heads up. Unfortunately, although as it stated the hours were low, it had no paperwork and was battered. Only purchased in 2008 but Trim / tilt worked intermittently as did the electric start and really crunched into gear, which put me off enough to not take it.
