i think the second hand prices can be justified, asking for 20K for a two door type r limited is about right assuming its a car in good condition, it is expensive but its like anything if someone wants one they will pay it, twincams are not 15k car but people are handing over that kind of money and some.
im not sure what the price for a clean type r in japan is now, but once you pay vrt tax insurance, nct which will probably require 4 tyres for e mark, Remap to suit our petrol, servicing timing belt etc. and if you want exhausts wheels suspension etc your going to be well north of 20 thousand and if they get harder to source in japan prices can only get higher, if the prices get much higher its very few people who can justify spending that much on a Toy
