Different interior, different wheels, different grille if you go pre 96, heck the real early ones like mine even had k10 washer jets, sadly that bonnet got bent years ago and i have the normal later type jets now, (shame as that often caused a few frowns).
Most SS' are old and quite rusty in general but you do see a few nice examples still floating around. We're starting to look for very old cars now though, finding a decent K11 is tough when you're looking in the 94-98 band, but there are still a few nice ones around if you're lucky.
Hope you find something Ian
