Just my humble two centsworth...
... but if Cessna are serious about raising Mustang sales they'll have to do something about that disgusting "emergency" lavatory... the existing facility is woefully inadequate when you consider the 'Stang's endurance. A real shame, otherwise a fine aircraft. A little potty and a dangling rag for your $ millions? The Phenom 100 knocks it out of the ball-park.
