I've gone ahead and bought some of the OEM Siata's - they come with brand new Michelin Pilot tyres too for £500 plus 30 quid courier.

These seem like a reasonable compromise and are a little different from the everyday sorts. I wanted OEM over replicas if truth be known.

I'll post some photo's once they're fitted - apparently they were an option on the New Beetle as well as some Seat's so they're still within the family so to speak, especially as lots of folk have Audi rims fitted!

Cheers
