Allow between £7,000 and £10,000 a year to run it.
That will include hangerage, T/O and Landing fees at the airfield you keep it, club membership, fuel, insurance and small maintenance jobs.
Not all are profitable (I lost £20,000 in three years when I sold my last one), but I agree that best purchase is Cessna or PA which will keep value.
Repair to my prop at one time came to £7,000.
That's 10 years ago.
