How about a z8?
 

I can't find the 'what would you like chris to build' anymore, but has anyone thought of a z8 replica?
Fits the criteria of
a similar shape to z3
originals worth a fortune (though that wouldn't influence my judgement) - if it looks good I don't care how little or much the original is 'worth'
It looks good (IMHO)

There is someone in the US that makes one. Pretty basic but the shape looks right.

Looks good - but doesn't look like they are producing them?
If only we could get the moulds?

old ebay listing. Would be careful about ordering, phone number in details
