Id certainly buy in to a group at Leeds/Bradford.
Where is the C172 Share based? Im learning at Sherburn at the moment and if its based there may be able to do a bit of digging for you regards the aircraft.
Or is it the 172 at Barton? G-AWVA?
Ive seen this advertised and it looks a nice aircraft,shame im not in a position to buy just now,got to finish PPL first.
However,if you decide to go down your own route,I would be interested in talking to you about it and your ideas of aircraft etc.
