I don't think there will ever be this "classic" status for the ZS.
XR3i - SRi - GTe - GTi - RS Turbo - are all iconic cars that started off the hot hatch and were all fast versions of what were accepted as brand/market area leaders - like the Escort, Astra and Golf
I doubt very much that the ZS180 will ever be held in such regard being likened to the Rover 45 which was hardly at the top of it's peer group. We love them though .....
If you don't have the standard bits - take them in trade for the bits you've got - you'd end up with a standard car - and we'd all benefit.
