Just thinking too, it's probably a smart choice to make something retro.
Mostly the people with the money and time to commit aviation are 60 - 80+ years old.
Probably a good proportion of them prefer the nostalgic lines, polished aluminium look and all aluminium build, to the plastic fantastics.
Being a single seater isn't a problem for them, as their wives are trying to get them out of the house anyway...
