You will find that it is the components in the engine, not the complete item, which never match up, so you will have a 1/2 turbine wheel due, then it might be a compressor split, then an FCU overhaul, then the 3/4 turbine wheels, it never stops.
If possible, get onto a "Power by the Hour" scheme, where you pay per flight hour to cover the scheduled maintenance, and if an unforeseen problem emerges it is covered too.
