Ebay is the best bet for buying over sea's it seems. I'm not aware of Topspeedtoys shipping out of the country, but if you could get it from them I'd check.

But I just searched Ebay and a few sellers ship worldwide.

You can also search ebay for Himato 1/8th scale buggy, and it will bring up the Himoto Torpeda, which is the exact same car.
