It has been on sale for 3 years for good reason!
Do a bit of homework on google and find out how much the resparring of the wing would cost along with the limitations that follow. C of A is also due and it hasn't been recovered since new (1976). I suspect an engine that hasn't flown for several years will also need a lot of work doing to it, if not replacing.
The figure we reckoned the owner would have let it go for and the money we would have had to spend on it meant we looked elsewhere.
The aircraft was sitting at Little Gransden last year and
AFAIK it is still there collecting dust, rat pee etc in the back of the hangar.
