But the plates aren't checked. Some of the ones listed in German series (for example) where no checking site exists:

For others there is no plate visible (so how can it be checked?):

The only ones that should be built in Argentina are European ones with verified 2011 plates:
http://www.imcdb.org/vehicle_565458-Volkswagen-Amarok-Typ-2H-2011.html (that one checks out)

or series from 2011 or early 2012:
http://www.imcdb.org/vehicle_472907-Volkswagen-Amarok-Typ-2H-2011.html (like here)

Other than that it should only be used on South American and Australian market (which are said online to be sourced from Argentina) ones.

I guess we shouldn't expect an apology for your rude behaviour here.
