and occasionally a Cessna 421 comes up for sale.
I know they have a geared engine and if you're ham fisted throttle jock you can screw it up letting the prop drive the engine.
But I have seen numerous comments like this below on many sites about astronomical annual inspection costs.


I'm not so naive to think that a Cessna twin is a bargain to operate but really? 50K Annually ?
4K for insurance (pilot dependent)
Hangar 6K-15K (location dependant)
Charts and other fees $1000
Annual is seriously going to 30K?
