Sounds about right to me....
Run out's didn't all come with Rainbow interiors - (Depended what body colour they were, Red, Blacks & greys came with a red 5 stripe, BBM Blue and whites had Aqua) or electric windows.
They did all have 16V rear lights. Just cos it's registered in '92 don't mean it was a 92 year model - could have been sat in storage for a while @ the dealers.
