Heard mercedes coming out new viano / vito next year.
http://www.topspeed.com/cars/mercedes/2013-mercedes-viano-vito-ar123019.html
But i guess it will cost more. Current Viano seems good
enough.
Probably they will modify
the face-lift abit here and there.... but the whole
structure is still intact....
This, the Hokkien
speaking.. Change
Soup.. No Change
Medicine... 
The new Viano (now) has only been in market for less than a year
(In Singapore)... even for 2013 production, it will only be 2 years
from it official released.... no commerical sense for them to
produce another version of Viano.
Actually, the current Viano has almost the same functions as the
older Vito, except for the front
lights (with day leon
lights), auto doors, blue-efficiency engine... the rest is
all about the same.
The structure of a "Van" is almost there.... (cannot changed to
other patterns...
). Only how to change the face-lift and
other ways to improve the vehicle. Maybe next time, the
passengers' seats will be more like Toyota
Alphards....
.. more comfortable....
