BMW E39 5 series shadow chrome alloys and tyres *

Bought my 530 fitted with these alloys. I think they are too dark with the navy blue car, look good on a lighter colour. So looking to swap these 18" chrome alloys for a set in silver finish to a similar condition and quality. Happy to consider 16" 17" or 18". Wheels are immaculate. 235 40 ZR18 matching set of tyres all with more than 5mm. Swap or sell for 375 which allows me to buy a replacement set.
