Has a fixed price for importing from Japan so amongst the cheapest options unless you do everything yourself or have a friend who does it.
And no need to worry about getting a cheap accident car for normal condition prices.
He takes his fee and you decide what condition car you want. His fee remains the same.
Comes highly recommended from the Swedish skyline forum

He doens't offer the same kind of guarantee though as normal import companies would as he only act as a "consultant" and has a smaller fee compared to regular import companies.
You decide what car you want in Japan And he helps you get it home and road legal.
Although if something goes wrong with the car I'm sure he will help you source the parts needed free of charge. You only pay for the part and freight.
A little riskier but on the other hand you'll probobly save some ???.
Oh, and every expenditure is showed on a very detailed spreadsheet. So you know exactly how much of your money is going to what.
