Rakuten seems to be the (a) method to purchase Japanese Copen parts. Anyone have experience of this or warnings. I just tested the water by regestering, filling a basket and going part way through the checkout. Carriage charge was unknown, I got so far as... "You will only be charged after confirming the shipping fee with the store."
I prefer to use a human - been using Jessie Streeter for years. He charges a commission, but it's worth it IMHO. I've spent about 2k EUR with him over the years, never any issues.
Got to give him credit too! Before I sold my Copen to a fellow member, I used Jessie to import a tonne of parts. Never let me down and was incredibly informative and packaged all the goods well too. Tremendous bloke and really good for advice too in terms of shopping about and what parts are good prices etc.
