In 1996 they changed in the series II model to have the extra chrome around the rear tail lights, and also having statesman written in lettering from one side to the other opposed to just the badge on the lower right corner of the boot. The series II onwards also got treatment of fake wood grain in the dash, 16inch wheels factory over the series I 15inch, slightly upgraded material on seats and got the update version of the ecotec motor which produced the same power but slightly different bolt ons.
Any statesman with lettering from one side to the other is a Series II & III VS
Any with the badge in the lower corner is a VR Series I and a VS Series I
