I think nr 2,14 and 15 look cool.
the pic that warpath showed us.. reading Scanias webpage (and im too lazy to convert from german to english) the model P is their regional and local truck (Freightliner M2?) and the 340 is for the 340HP engine, 11 or 12 liter!!
some pics from the Scania webpage here (I got way too much time on my hands, better go back to work)
