sorry, I guess being in Japan puts me somewhat out of the loop,
about price of GT-Rs on Japan....
the GT-R is one car that is `shaken` proof....as you all know, the Japanese rego system is pretty tough and most cars aren't kept by their owners.....The GT-R is an exception....it is a very very popular car for local lads.....
as for the GT-Rs for sale in Japan.....I can assure you that an early model GT-R, in good condition, with relatively low mileage (under 80k) still fetches decent money in Japan. The GT-Rs that you hear about going for 10k in Japan are the rough ones....and believe me, there are lots of rough skylines in japan....No doubt the number of skylines exported to Australia, NZ, and GB, also has an affect on local price too.....I owned a GTiR Pulsar here, and in the 3 years I had it, I saw perhaps only 4 others on the road.....i always say more on the road in Australia when home for xmas....
