If you wanted to add some detail with plasticard, the cab side window and passengers windows are split. Window size may be different as is the number of windows before the door (5 versus 6), side name boards and of course a luggage rack. The front destination board is wider and you'd need to add a rear view mirror, indicator, small boxy thing and a new profile where the first passenger window meets the roof of the half-cab....depending on how close you want to get it to that prototype
