is your insurance provider going to buy you brand new parts shipped from japan?
but kenwood is still a POS compared to meile and carrier - why not import that personally - like your JDM spare parts.
hmm - let me check again, my late father was an old seasoned banker, he worked in 3 international banks in different parts of the globe, his choice of cars were always local supported. his reasoning was - he is not a mechanic, he needs his car to work as a tool for transport to his work.
btw - japan has very special items too, breads like a womans genitalia, vending machines with used undies etc etc. infact vending machines are famous in japan - its said that you can find any and every item in a vending machine in japan.
