Much as I like the Porsche wheels, I think I'm probably gonna go with a BBS X Spoke lookalike.
For about £500 I can get something like the Rondell Design 58's in 15" including cheapo tyres.
Where as the Porsche Design 90's are likely to be over a grand once you've; bought the rims, had them polished, bought the adapters, then fitted tyres.
Still worth dreaming about though.
