Jeezuz Tailie, are you gettin all soft and subtle in yer dottage??
The lies and total garbage I've heard from aircraft sales people over the past 45 years make used car salesmen look like saints!!
I know a fool and his money are easily parted, but surely any potential buyer of a PT6 powered Beech Duke would check the veracity of the operating costs provided, realise they are total garbage and conclude that the vendor has no integrity?
Then again, any one that would buy a Beech Duke probably isn't really all that smart...... As I said, a fool and his money are easily parted!
