Buy a Light Aircraft Association light aircraft.
You can get a good number for less than 10k and then fly your socks off at around £20 an hour.
And if you chose the right one, then sell it for what you paid!
Planes and Aircraft For Sale - Light Aircraft, Autogyros, Helicopters ... (UK) will give you ideas. Then ask local LAA pilots for thoughts. Your EASA SEP instructor probably won't have a clue!
You could even hangar it at Strathaven!
