Well, is this a freaking awesome coincidence or what? I arrived to the airport in Tokyo with Mikingo and BOOM, we saw this RX7 for sale in Shibuya which is only a few km's away. The price was 9500V$ but we negotiated a bit, because maybe we'll buy another car. Thanks to @tyretear for this FD.
Yeah, and about that "another car", we already found it. Benjamin told me about a 200SX in Bosnia, it's very cheap so it's worth going to Europe again. We'll go there tomorrow and come back to Japan soon.
