As someone who supply's the hour building market I resent your assumption that all aircraft are slow & clapped out.
My C152's are slow but not clapped out they make the book numbers, the engines are overhauled by reputable agency's, not the cheapest and the maintainence is EASA 145........ Not part M.
Supplying well maintained aircraft pays me in terms of less unscheduled maintenance and most of my business coming from recommendations from customers.
Just because the market is dominated by unloved aircraft with shabby paint and an interior that smells of the pond life living in the carpets, it is not true that all in this sector offer the usual inferior product.
