Hi Nick,
Well the "getting too old for this crap" certainly strikes a chord. I don't know if the subject has been dealt with already on this forum, but you wonder if people, shall we say under 50 buy kits of historical aircraft anymore, rather than more modern aircraft (if even those). I suppose they must or why do the manufacturers produce them? Unless of course there's a EU 1/72 F4U mountain standing somewhere in the Netherlands unreported by the media.
Regards,
Clint
