Interesting discussion thus far... couple of quick observations / questions.
1. Cirrus is very much focused on marketing their product as a "lifestyle" tool. This is very attractive for the up-and-comer type. It may not be as attractive to the analytical, engineering, pilot-purest type. Selling top speed is a narrow, abstract idea, that appeals to some, but clearly isn't drawing in folks who have other valid concerns. Airplanes are tools that allow people to accomplish things, things that are often impossible without the tool itself. Speed is one dimension of a tool's value, but often not the most important. I would suggest that speed in context with its result might be something to share.
2. Mooney, to my knowledge, does not sell direct to their customers, which puzzles me. I am too new to the business end of aircraft sales to understand if this is a common practice or not, but it may enable them to have a certain "arms-length" mentality regarding their customers.
In my business of software engineering for our product development teams want nothing more than direct, unmediated access to their existing and potential customer base in order to understand exactly what their problems are and what they want so they can figure out how to deliver something a customer is will to pay for. This is exactly what Bob Kromer did personally when he developed the venerated 252. You can hear him say it here himself: https://youtu.be/YZTlWHHRrJ0?t=266
The pilot-side door in the latest models was a positive step in the right direction, which I hope was inspired by good dialogue with their customer base. I'm looking forward to seeing more of this, and, as I have elected to earn more, hope to one day have the ear of their product folks myself!
Good discussion, all.
