It may not be “the” MINI Wagon but it is “a” MINI Wagon. It's been designed and built by Carrozzeria Castagna, a high-end Italian coach builder. The concept is based on the old Austin MINI “Countryman”. You can find out more here – that is assuming you can either read or figure out Italian 🙂
As someone mentioned on a MINI2 thread – if you have to ask about how much it is… you probably can't afford it.
You can see some screen shots of the flash site here.
