Do you mean the difference between the earlier 4x4 models and the later facelifted ones? The last cars had different alloys facelifted interior (different dashboard etc) and the seats were a darker grey (called 'space') with little red and blue dots. The only options on the last cars were air conditioning or a 2008 CD player, never seen heated seats as an option tho I think they were in some colder countries!
