Capital outlay for your share will probably be £6000
Should be able to get two or three aircraft shares for that, unless you are looking for something a bit newer and more upmarket.
A share in your average spamcan (PA28 C152) will cost you somewhere between £1600 - £2400). Several low houred (engine) PA28's on our airfiled going for around £1800. Monthly is £60 and hourly (wet) is also £60.
Popham is a good source of very reasonably priced shares in group owned aircraft.
