I was browsing e-bay (as you do) for Stepwgn bits, and clicked on the link for 'see all international sellers' - this brought up several pages each of 50 items - mostly from a company called UKEROO in Japan - the adverts were in English.
I was a bit surprised at the prices (the stuff is second-hand with no guarantee) - but even more by the transport charges.
Examples are 1) rear door assembly at just over £100, but transport charges over £1000, and the same for a fuel tank.
Door mirror assemblies range from £125 to £250, but again transport very high.
(When you think about it, it only costs about £1200 to bring over the whole vehicle!)
