There are a few very well heeled Japanese collectors
who have VERY deep pockets when it comes to
items they want (i.e. $4200 simplex derailleur, $2000 campy bar end shifters, and a cheap $920. Brooks saddle).
These guys are collectors, and resellers in Japan, are
very patient and know what they want. There have been
numerous discussions concerning the huge amount of sales (and prices) of all things French going to Japan.
And besides, if you just sold a bike for $12k wouldn't you
leave lots of positive feedback?
