Must be part of a joint agreement as the chinese would never be able to copy it that closely. Its also not popular enough to do a cheap chinese rip-off, Scenics and VWs maybe but not an oddly styled fiat.
I wonder if they have set up new tooling over in China or this might be the multipla being phased out of euro production.
Also I saw on the italian Fiat site they make a specific taxi spec Multipla, with the amount of airports being built in China maybe this will be a boom market for a few years.
