Cost per year over 10 years

[Osage2112]

Is the cost per year over 10 years, (insurance included) comparable to other twin engine planes?

Is the 337 average or is it truly more expensive to own???

I've heard the 337 is more expensive, but that could be due to an abused plane needing to be "caught up" on maint.

I'd like to consider a 337, but need to know from the forum first.

Thanks,
