Just as in the UK there will be people telling you that you can buy aircraft for very low prices.......................But you will have little engine life, old avionics, worn paint, and just about all the rest will be worn almost to limits.
In the UK at the moment there are two aircraft markets, the one you see in the papers were you can buy a C152 or the like for £16K and the market that you wont see were a C152 that is fully sortted and ready to do a years hard work trades for £35K to those who know the costs involved in getting aircraft into a reliable state.
The best advice I can give is to get the aircraft inspected by a mecaninc who knows the type, only then can you go in with your eyes open as to the real cost of ownership.
