Good luck trying to find a genuine silver set (18") for sensible money, they are rarer than rocking horse manure.
There is a brand new set on ebay for £1199 without tyres.
I originally wanted a silver set for our car to replace the diamond cut wheels, but due to how rare they are, I eventually settled on the matt dark graphite grey same as per the link above.
VW were selling 4 x Pretoria 18" matt dark graphite wheels with Continental premium contact 6 tyres (225/40R18 92Y XL) for £1360 not so long ago. It might be worth seeing if anyone has old stock if you do consider this colour.
