Except for two things, I love it. Except for USD $665,000 and the statement "I believe it’s close to being a great performer with only a couple minor changes", I think I´ll pass...
I was impressed with the level of engineering for a civilian (funded) craft. Although I've never worked on amphibious vehicles, I'd like to have been involved from an early development stage. Achieving plane would have been a non-issue. Certainly, evacuating the wheel wells would help, but the use of a surface drive in a tunnel environment is the definition of ventilation.
Was the designer a flight engineer in a previous life or did he just have a thing for guages that only the passenger could ever read? It really looks like those pax side guages are there just because he had them laying around and the panel had room for another one. I have seen fewer dials in the control room of a steam ship.
Now that you mention it, it does look a promotional shot out of a Livorsi catalogue. Which one is the fun meter?
It should have been on Barrett Jackson last night, bet he could have got atleast a couple hundred for it! 10-15 yrs ago he fabricated a land/yacht out of a stainless steel milk trailer, dubbed the "Dobbertin Surface Orbiter" he stopped in Ft Lauderdale at Lesters dinner for the press! http://www.dobbertinhydrocar.com/Dobbertin Surface Orbiter.html
