Look for some used genuine wheels and get them refurbished in black or whatever colour you want, rather than buying terrible aftermarket wheels. It'll probably cost less and you can be sure of fit.
eg https://www.volvoclub.org.uk/pdf/c30/C30PDFPriceListMY08.pdf - page 3 - 17" Serapis are similar to (and IMO nicer than) the 5 spokes you posted earlier.

A much better idea, and can't believe this post has been ignored.
If kept stock colour, then I wouldn't even bother declaring them to your insurer.
