Cirrus = a triumph of clever marketing over real substance.
In many other arenas I might agree with you. I might even agree with you in this arena it is a factor.
However I think you devalue the intelligence of most pilots and particularly those with half million dollars to spend who, in the majority, are unlikely to be entirely stupid.
The facts speak for themselves Cirrus are still rolling aircraft off the production line and selling them, whilst Mooney have closed the production line.
I have flown three variants of the Mooney. It is a fine aircraft but cramped and claustrophobic. More imortantly too many man hours go into making a dated airframe that eschews mass production techniques. As the boat industry realised many moons ago you cant compete with something that falls out of a mould and that is why almost nobody makes wood boats these days.
